INTRODUCTION Welcome to AERIS and thank you for choosing the XR1 ! It is extremely important that you read this Owner's Guide in sequence and understand it completely before attempting to use the XR1. Remember that technology is no substitute for common sense, and a dive computer only provides the person using it with data, not the knowledge to use it. The XR1 has numerous features that are described throughout this manual. DI RESP O VER Be a RESPONSIBLE DIVER at all times.
BAR GRAPHS Nitrogen Bar Graph The Nitrogen Bar Graph (Fig. 2a) represents tissue loading of nitrogen, showing your relative no decompression or decompression status. The Nitrogen Bar Graph monitors 12 different nitrogen compartments simultaneously and displays the one that is in control of your dive.
Deeper than 60 feet (18 m) Segments Ascent Rate = Displayed FPM MPM 0 0-20 0-6 1 21-50 6.5-15 2 51-60 15.5-18 3 >60 >18 60 feet (18 m) & Shallower Segments Ascent Rate = Displayed FPM MPM 0 0-10 0-3 1 11-25 3.5-7.5 2 26-30 8-9 3 >30 >9 VARI Values Variable Ascent Rate Indicator (VARI) The Variable Ascent Rate Indicator (Fig. 3a) provides a visual representation of ascent speed (i.e., an ascent speedometer). Gray is a 'normal' rate, yellow a 'caution' rate, and red is 'Too Fast'.
Time Displays Time displays are shown in hour:minute format (i.e., 1:16 represents 1 hour and 16 minutes, not 116 minutes!). The colon that separates hours and minutes blinks once per second when the display is indicating real time (e.g., Elapsed Dive Time), and is solid (non-blinking) when times are calculated projections (e.g., Time to Fly). The Main Time display has the largest digits of the display (Fig. 4a) A second time display (Fig. 4b) is located above it.
POWER SUPPLY The XR1 utilizes one (1) type CR 2450 Lithium 3 volt cell that should provide approximately 300 Hours of continuous operation, or 50 activation Periods of operation. If you conduct 1 dive each time the unit is activated, you should obtain approximately 50 dives. If you conduct 3 dives each time the unit is activated, you should obtain approximately 150 dives. Battery Indicator A Battery Indicator provides an indication of battery condition.
Low Battery Condition Voltage level is checked upon activation and every 10 minutes during operation. If a Low Battery Warning Condition exists (< 2.75 volts, > 2.50 volts), the Battery icon (shell and lower segment only) will be displayed solid as previously described (Fig. 7a). If the Battery is not changed and voltage continues to decrease until a Low Battery Alarm Condition exists (< 2.50 volts), the Battery icon (shell and lower segment only) will flash once per second for 5 seconds (Fig.
DIVE TIME REMAINING (DTR) One of the most important pieces of information on AERIS dive computers is the 'Dive Time Remaining (DTR) display'. The dive computer constantly monitors no decompression status. No Deco Dive Time Remaining (DTR) No Deco Dive Time Remaining (DTR) is the maximum amount of time that you can stay at your present depth before entering a decompression situation. It is calculated based on the amount of nitrogen absorbed by hypothetical tissue compartments.
WARNINGS AND SAFETY RECOMMENDATIONS It should not be considered that the capabilities built into the XR1 provide an implied approval or consent from AERIS for individuals to exceed the defined limits for recreational diving, as agreed on by all internationally recognized training agencies. The XR1 provides information based upon a personal dive profile, and therefore must not be shared between divers.
NOTICE WET ACTIVATION The XR1 is configured with contacts that will automatically activate the unit when the space between the contacts is bridged by a conductive material (immersed in water). The contacts are the pins of the Data Port and stem of the Push Button. It is important that the Data Port and Button be kept clean and free of any contamination or debris that could cause the unit to activate unnecessarily resulting in premature depletion of battery power.
WARNING: Prior to diving with the XR1, you must also read and understand the AERIS Dive Computer Safety & Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
ACTIVATION To Activate the XR1 - press and release the Button. Fig. 10 - Diagnostic Mode Upon manual activation, the unit will enter Diagnostic Mode (Fig. 10), displaying all segments of the LCD as 8's, followed by dashes, then a countdown from 9 to 0. Diagnostic Mode checks the display and battery voltage to ensure that everything is within tolerance and functioning properly. It will also check the ambient barometric pressure, and calibrate its present Depth as zero.
Wet Activation (only if set ON, a user setting) The XR1 will also automatically activate by water contact. This is accomplished by bridging the gap between contacts located on the Button and Data Port on the side of the housing. If no dive is made within 2 hours after activation, the unit will deactivate. If the wet contacts are still wet, it will reactivate. SURFACE SEQUENCE While on the surface, the unit will automatically scroll through a Sequence of displays including - Fig.

WARNING: Prior to diving with the XR1, you must also read and understand the AERIS Dive Computer Safety & Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
DIVE MODE BAR GRAPHS As your depth and elapsed dive time increase, the Nitrogen Bar Graph (NiBG) will fill with segments (gray toward red) to represent the absorption of nitrogen (Fig. 22a). While ascending to shallower depths, the segments that have filled the Bar Graph will begin to recede, offering a graphic representation of your multilevel diving capability. a b Fig. 22 - NiBG & VARI The Variable Ascent Rate Indicator (VARI) shows how fast you are Ascending (Fig. 22b).
During conditions in which cautionary type information is displayed (e.g., Decompression, etc.), there is one Main (Default) Display of important information relevant to the specific condition. You can then access Alternate Displays, that will automatically revert to the Main Display after 3 seconds. NO DECOMPRESSION DIVE MODE The XR1 will enter the No Decompression Dive Mode when you descend to 5 feet (1.5 meters). No Decompression - Main Display 1 (Fig.
No Decompression - Main Display 3 (Fig. 26) Information includes Current Depth (and FT or M icon), Temperature (and degree icon with graphic F or C), Time of Day (and clock icon), Dive Time Remaining (and wave/clock/profile Mode icon), and applicable Bar Graphs. Press and release the Button to view Main Display 1. Fig. 26 - No Deco Main 3 No Deco - SAFETY STOP (Fig.
DECOMPRESSION DIVE MODE The XR1 is designed to help you by providing a representation of how close you are to entering decompression. Decompression Dive Mode activates when theoretical No Decompression time/ depth limits are exceeded. Upon entering Decompression Mode, you should begin a safe controlled Ascent to a Depth slightly deeper than, or equal to, the Required Ceiling Stop Depth indicated (Fig. 28a) and Decompress for the Stop Time indicated (Fig. 28b).
DECO Stop Main (Default) Display information includes (Fig. 29) - Current Depth (and FT or M icon), Required Ceiling Stop Depth and Time (and clock icon), Total Ascent Time (and wave/ clock/deco bar/profile Mode icon), and applicable Bar Graphs. Total Ascent Time (Fig. 29a) includes Stop Times required at all Ceilings and vertical Ascent Time calculated at 60 feet (18 meters) per minute below 60 feet (18 meters) and 30 feet (9 meters) per minute at and above 60 feet (18 meters). a Fig.
DECO Stop Alternate Display 2 (Fig. 31) Information includes - Current Depth (and FT or M icon), Temperature (and degree icon with F or C graphic, Time of Day (and clock icon), Total Ascent Time (and wave/clock/deco bar/profile Mode icon), and applicable Bar Graphs. Press the Button to return to the Main Display. VIOLATION MODES Violation Modes that the XR1 can enter are termed Conditional, Delayed, and Immediate. Permanent Violation Mode and Violation Gauge Mode are continuations of these. Fig.
If you descend below the required decompression ceiling before 5 minutes have elapsed, the unit will continue to function in Decompression Dive Mode. In this case, no off-gassing credit will be given, and for each minute you were above the ceiling 11/2 minutes of Penalty Time will be added to Required Stop Time. The added Penalty (decompression) Time will then have to be worked off first, before obtaining off-gassing Credit.
If your Decompression obligation requires a Stop Depth 'between' 60 feet (18 meters) and 70 feet (21 meters), the full Nitrogen Bar Graph will flash (Fig. 34). Total Ascent Time will be displayed. You must Ascend to just deeper than, staying as close as possible to, 60 FT (18 M) without causing Total Ascent Time to flash. When the Required Stop Depth indicates 50 FT (15 M), etc., you can ascend to those depths and continue decompressing. Flashing Fig.
Immediate Violation and Violation Gauge Mode During a Dive, if a Stop Depth greater than 70 FT (21 M) is required, an Immediate Violation Mode will be entered. This situation would be preceded by entering Delayed Violation 2, previously described. Flashing Fig. 36 - Violation Gauge Mode (underwater Main) The XR1 would then operate with limited functions in Violation Gauge Mode during the remainder of that dive and for 24 hours after surfacing.
On the surface, Violation Gauge Mode displays the Dive Number, Temperature, Time of Day, Surface Interval, and the full Nitrogen Bar Graph flashing (Fig. 38). It does not provide the Dive Planner or the Time to Fly feature. The countdown timer that appears with a single dash during the Surface Sequence (Fig. 39) is only provided to inform you of the time remaining before Normal operation can resume with full dive computer features and functions.
USER SELECTED DIGITAL GAUGE MODE When Digital Gauge Mode is set for ON, the XR1 will operate as a Digital Depth Gauge/Timer without performing nitrogen calculations. While in this mode, the range of the Current and Maximum Depth displays are extended to 399 feet (120 meters) to accommodate activities involving diving with advanced breathing gas mixtures or free diving beyond the normal depth limit of the unit. Fig.
WARNING: Prior to diving with the XR1, you must also read and understand the AERIS Dive Computer Safety & Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
POST DIVE SURFACE MODE When you ascend to 3 feet (1 meter) or shallower, the unit will enter Surface Mode and begin counting your Surface Interval. TRANSITION PERIOD The first 10 minutes is, in affect, a Transition Period during which time the following information is displayed (Fig. 41): Flashing Flashing Fig.
Log Data will not be stored in the unit's memory until the 10 minute Transition Period on the surface is completed. Once 10 minutes have elapsed, the Surface Mode icon and Surface Interval time display colon stop flashing indicating that the Dive and Transition Period are completed, and a subsequent Descent will be considered a new dive. If you Descend during the 10 minute Transition Period, time underwater will be considered a continuation of that dive.
If a Violation occurred during the dive a single dash ( - ) will appear instead of the letters FLY (Fig. 45). DeSat time will not be displayed. The Time to Fly counter is provided to assist you with deciding when enough surface time has elapsed to fly (or travel to higher elevations). Fig. 45 - Countdown (after a Violation dive) After a surface interval of 12 hours, you may choose to fly (or travel to higher elevations), provided that your dive profile(s) did not enter decompression.
Once the Log is full (12 dives), each subsequent dive will then overwrite the oldest dive stored in the Log. It is therefore suggested that you transfer the Log's data to your log book at the end of each day of diving. Log data will not be lost when the battery is removed/replaced, however, factory service and calibration will delete the data. The first dive conducted each time the unit is Activated will be #1, therefore there may be multiple #1 dives in the Log.
Dive Data (the second Log screen) includes (Fig. 42) Maximum Depth - reached during the dive (and MAX and FT or M icons) Log Mode icon Temperature - minimum during the dive (and degree icon with graphic F or C) Surface Interval - prior to that dive (and clock/wave icon) Elapsed Dive Time (and wave/clock icon) Variable Ascent Rate Indicator - showing the maximum Ascent Rate maintained for 4 consecutive seconds during the dive.
AFTER THE FIRST 2 HOURS Two hours after the last dive, the Surface Sequence will no longer be displayed. The Time to Fly and Time to Desaturate countdown screens will be displayed alternately for 3 seconds each until they count down to 0:00 or another dive is made. If the Wet Activation Contacts are wet, the graphic H2O will appear on the displays (Figs. 49/50). To access other modes or enter settings Press the Button to reactivate the Surface Sequence.
RESET FEATURE The XR1 is configured with a RESET feature that allows data to be cleared, including Nitrogen calculations and Log Mode entries. WARNING: Reset after a dive and subsequent use for a repetitive dive conducted by the same diver could result in serious injury or death. Fig. 51 - Reset (Clear) 44 Reset Procedure While the Surface Sequence is scrolling, press and release the button to access the Log Mode's first Preview screen. Press and release the button again to access the Data screen.
WARNING: Prior to diving with the XR1, you must also read and understand the AERIS Dive Computer Safety & Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
CARE AND CLEANING Protect your XR1 from shock, excessive temperatures, chemical attack, and tampering. Protect the Lens against scratches with an Lens Guard/Protector. Small scratches will naturally disappear underwater. CAUTION: Never spray aerosols of any kind on, or near, the instrument. The propellants may chemically attack the plastic. b WARNING: Never force any object through any slots or holes of the Housing.
WARNING: If a Low Battery Condition is indicated prior to a dive, DO NOT attempt to dive with the XR1 until the Battery is replaced. INSPECTIONS AND SERVICE Your XR1 should be inspected annually by an Authorized AERIS Dealer who will perform a factory prescribed function check and inspection for damage or wear. To keep the 2 year limited warranty in effect, this inspection must be completed one year after purchase (+/- 30 days).
To Obtain Service Take you XR1 to an Authorized AERIS Dealer or send it to the nearest AERIS Regional Distributor Facility. To return your XR1 to AERIS: Record all dive data in the Log and/or download the data in memory. All data will be erased when it receives factory service. Package it using a protective cushioning material.
To prevent formation of moisture in the Battery Compartment, it is recommended that the Battery be changed in an environment equivalent to the local outdoor temperature and humidity (e.g., do not change the Battery in an air conditioned environment, then take it outside during a hot sunny day). Battery Hatch Removal Locate the Battery Compartment on the back of the Module.
Battery Removal Remove the Retaining Bar located across the lower portion of the Battery (Fig. 54a). Remove the Hatch O-ring. DO NOT use tools Using care not to damage the Battery Contacts (Fig. 54b/c), slide the Battery up and out of the Battery Compartment. CAUTION: Do not allow a metal object to short circuit the top of the Battery which is positive (+) to the negative ( - ) contact of the Battery Compartment.
Battery Installation Slide a new 3 volt type CR2450 Lithium Battery, negative (-) side down into the Battery Cavity. Slide it in from the right side and ensure that it slides under the contact clip on the left rim of the cavity (Fig. 55). Orient the Retaining Bar across the lower portion of the Battery and carefully push it down into position (Fig. 56).
Fig. 58 -Engaging Retaining Ring Using your fingers, turn the Ring counter clockwise 5 degrees until the tabs engage (Fig. 58), then tighten it 5 more degrees by turning it counter clockwise with the aide of a small blade screwdriver (Fig. 59). While tightening the Retaining Ring, exert continuous inward pressure on it until it is secured in the proper position. A small symbol located on the Ring should be aligned with the Locked symbol located on the Housing (Fig.
ALTITUDE SAMPLING/COMPENSATION Atmospheric pressure decreases as altitude increases above sea level. Weather systems and ambient temperature also affect barometric pressures. Consequently, depth reading instruments that do not compensate for the decrease in pressure indicate depth readings shallower than the depth they are actually at. The XR1 automatically compensates for decreased ambient pressure when activated at high altitudes up to 14,000 feet (4,270 meters).
