English This is a combination (analog and digital display) diver’s watch with a depth meter installed. When diving, various data related to diving (present depth/diving time/maximum depth) appears on the digital display. Apart from the log data memory function which records the diving data from four dives, there is also a ascending speed alarm function which warns the diver with an alarm sound if the ascending speed is too fast.
CAUTION Before using the watch, read this instruction manual carefully for safe and correct use. After reading this manual, keep it for your further reference. Safety precautions - Instructions to be followed at all times.
WARNING Diving is a fundamentally dangerous sport. When diving with this watch, make sure you fully understand and follow the instructions on handling described in this manual. Recreational diving involves risks. Use this watch for diving after you have undergone scuba diving training from a qualified instructor, obtained the necessary experience and skills for safe diving, and fully understood the watch’s handling operation.

A. DIVING WITH THIS WATCH CAUTION DIVING WITH THIS WATCH WARNING DEPTH METER FUNCTION • Only use this diving watch after undergoing correct instruction and training in diving and always obey the accompanying rules. • Make sure you fully understand the handling of the watch and the caution items in order to use it correctly. Please note that the watch may not function correctly if you handle it other than as indicated in this instruction manual.
PROHIBITION PROHIBITION WHEN DIVING Do not use this watch for diving in the following cases. • When the low battery warning function is activated. ... When the life of the battery is nearing its end, the second hand moves in 2 second intervals. • When the watch stops or exhibits any abnormal functioning. • The depth measurement is outside the assured temperature range. ... The temperature range in which the accuracy of this watch’s depth meter is guaranteed is +10˚C - +40˚C (50˚F - 104˚F).
< During diving > • Avoid ascending very quickly to prevent your body from being affected by the bends, etc. Surface at a safe speed of within 9m/30ft. per minute. This ascending speed is in accordance with the U.S. Navy Diving Manual (1993 edition). • Never operate the crown or any buttons except button A when underwater. Doing so may result in a fault such as poor water resistance. • Be careful because the alarm may be hard to hear underwater because of the sound of your breathing.

H. HOW TO USE THE LOG MODE Log Mode When you switch to Dive Mode and start diving, this watch automatically records the log data (log no., date, dive start time, maximum depth and dive time) for the 4 most recent dives. You can recall this log data after the dive. < Switching the Log No. > (1) In any of the Time Modes, press button M for 2 seconds or more to set the Log Mode.
• If there is no log data recorded, “----” appears on the Log No. display when you press button A. • When the abnormal depth alarm (“ER” is displayed) is activated during a dive, the maximum depth data flashes on the display. • If something goes wrong with the pressure sensor, “Log No.” and “ER” are alternately displayed when you recall the log data. • When you start a new dive, the log data of the oldest of the 4 dives recorded is automatically erased.
I. HOW TO USE THE DEPTH/DIVING TIME ALARM There are the following 2 alarm functions in this watch’s Diving Modes. 1 Depth alarm function: • Set range: 1m-80m/5ft-260ft (1m/5ft units) • The alarm sounds for 15 seconds when you reach the set depth while diving. After the alarm sounds once, if you continue diving deeper than the set depth then the alarm repeatedly sounds for 15 seconds every 1 minute. If you return to a shallower point than the set depth, the alarm stops.
2. HOW TO SET THE DIVING TIME ALARM (1) Press button M to switch to the Diving Time Diving time (minutes) Alarm Mode. The diving time display flashes on and off. (2) Press button A to display the time when you want the alarm to sound. The diving time alarm B A DIVE setting is now completed. Each time you press button A, you can adjust the diving time in increments of 5 minutes from 5 ➡ 10 ... 305 ➡ 310 ➡ -- ➡ 5 ... . You can adjust quickly by keeping button A M pressed down.

K. THIS WATCH’s WARNING FUNCTIONS This watch has the following 2 warning functions. Please use them as a guide for safe diving. 1. ASCENDING SPEED WARNING FUNCTION 0m 15.0m DIVE 25.0m 44 DIVE If the ascending speed during a dive exceeds 1.5m (5ft) per 10 seconds, this alarm sounds for 10 seconds as a ascending speed warning. When the ascending speed warning alarm is sounding, the digital display alternately shows SLW and the current depth.
L. IN CASE OF THE FOLLOWING [The second hand moves at 2-second intervals] The battery is nearing the end of its life, and the low battery warning device is working. When this happens, replace the battery as soon as possible. (Even when this happens, the watch still keeps the correct time.) Note that the following cannot be done when the watch is in this state. 1. The alarms do not sound. 2. You can switch to Diving Modes, but not to Dive Mode. 3.
[If the watch’s display or operation is abnormal] If a strong impact or strong static electricity is applied to the watch, abnormal display or operation (such as the digital display malfunction or the alarm continuing to sound) might occur on a rare occasion. If this happens, carry out “M. ALL RESET”. M. ALL RESET All Reset cancels all stored data, so please record any necessary data in a logbook beforehand. [After battery replacement] After replacing the battery, always carry out procedures in “M.
N. BATTERY 1 Battery life The life of the battery is about 2 years after installation. < Approximate conditions of use > Time alarms: 15 seconds/day No. of dives: 50 dives/year (time of 1 dive: 1 hour) • Depth alarm ... 45 seconds/dive • Diving time alarm ... 30 seconds/dive The life of the battery may be shorter depending on how much the alarms, chronograph, etc. are used and depending on the number of dives and the time of each dive.
1. REGISTER RING 20 50 30 The register ring means the rotating bezel fitted around the watch body. • This is used when measuring elapsed time or time 40 remaining. < Using the register ring > Before starting a dive, rotate the register ring to the left so that the • mark is lined up with the minute hand. You can know the elapsed time from that point by reading what the minute hand indicates on the scale on the register ring.
