GETTING ACQUAINTED

Precautions

• This watch is intended for use up to skin diving and snorkeling. It is not

designed for use during scuba diving.

• Never operate the buttons of the watch while underwater or while floating on

the water’s surface.

Before Skin Diving/Snorkeling

• Before beginning skin diving or snorkeling, check to make sure that none of

the following is shown on the display.

❑ HELP message (indicating a weak battery)

❑ Flashing display (indicating a weak battery)

❑ SENSOR Error message (indicating sensor malfunction)

• Make sure that the watch is set to the correct time of day.

• Check the glass, case and band for cracks or chips.

• Make sure that the band is fastened securely around your wrist.

While Skin Diving/Snorkeling

• Check to make sure that timer operation and depth measurement are being

properly.

• If the indicator “ ! ” appears on the display, it may indicate bad data.

• Take care when skin diving/snorkeling near rocks or coral to avoid scratching

the watch.

After Skin Diving/Snorkeling

• To avoid corrosion, rinse your watch thoroughly with fresh water to remove

salt water, dirt, etc. (When possible, soak the watch in fresh water overnight to

make sure that all salt is removed.)

• When using a metal band, occasionally clean inside the gaps in the band

using a soft toothbrush and soapy water. Failure to do so can result in

corrosion of the timepiece, soiling of clothing or irritation to sensitive skin.

GENERAL GUIDE

• Press C to change from mode to mode.

• Holding down C for 2 seconds enters directly into the Depth Measurement Mode from any other mode.

• In any mode, press L to illuminate the display.

TIMEKEEPING MODE

• In the Timekeeping Mode, press D to switch between

time and date displays.

To set the digital time and date

1. Hold down A while in the Timekeeping Mode until the

seconds digits start to flash on the display. The seconds

flash because they are

selected

2. Press C to change the selection in the following

3. While the seconds digits are selected (flashing), press D to reset the seconds to

“00”. If you press D while the seconds count is in the range of 30 to 59, the

seconds are reset to “00” and 1 is added to the minutes. If the seconds count is in

the range of 00 to 29, the minutes count is unchanged.

4. While any other digits (besides seconds) are selected (flashing), press D to

increase the number or B to decrease it. Holding down either button changes the

current selection at high speed.

While the 12/24-hour setting is selected, press D or B to switch between the two

formats.

5. After you set the time, format, and date, press A to return to the Timekeeping

Mode.

• If you do not operate any button for a few minutes while a selection is flashing,

the flashing stops and the watch goes back to the Timekeeping Mode

automatically.

• The day of the week is automatically set in accordance with the date.

• The date can be set within the range of January 1, 1990 to December 31, 2029.

To set the analog time

1. Pull the crown out to stop the seconds hand. If you plan to restart analog

timekeeping on some time signal (from the radio or television), pull the crown out

when the seconds hand is at the 12 o’clock position.

2. Set the hands by turning the crown.

3. Push the crown back in to restart timekeeping.

• Analog time is kept by a mechanical timepiece. Because of this, the seconds

hand may not start to move exactly when you push the crown back in.

• You can set the analog time to match the digital time setting, or you can set it to a

different time.

DEPTH MEASUREMENT MODE

The pressure sensor of this watch provides useful skin diving/snorkeling data. Besides

automatically measuring depths in the Depth Measurement Mode, the watch also

stores 10 sets of depth data into log memories for later recall.

You can also change the measured values displayed by the watch between meters

(M) and feet (F).

• See “HELPFUL HINTS ON DEPTH MEASUREMENT FUNCTIONS” for more

detailed information.

Important!

This watch is designed to start depth measurements and record data in the log

memory after a depth of 1 meter (4 feet) is reached. Because of this, the explanations

in this User’s Guide uses the term “ submerged ” to refer to any depth deeper than 1

meter, and the “ on the surface ” to refer to any depth shallower than 1 meter.

Understanding the Depth Measurement Mode display

*1 Hold down B to display the total time submerged. Always perform the operation to

display the total time submerged on land or on a boat. Do not perform it while in the

water.

*2 Hold down D to display the maximum depth. Always perform the operation to

display the maximum depth on land or on a boat. Do not perform it while in the water.

To switch between meters and feet

1. While not submerged, enter the Depth Measurement

Mode. The depth display should show 0.0 M or 0 F.

2. Hold down A until the M or F (whichever is on the

display) starts to flash.

3. Press D to select either meters (M) or feet (F).

4. After you make your selection, press A to return to the

Depth Measurement Mode.

About the log memories

You can store up to 10 sets of log data in memory. Once memory is full, it is updated

by recording the newest data and deleting the oldest data.

The following data is stored in memory for each measurement.

• Submerged (Depth) time —— Accumulated time (hours, minutes, seconds) you are

submerged

• Maximum depth

2385-3 HELPFUL HINTS ON DEPTH MEASUREMENT FUNCTIONS About depth and water pressure Water pressure increases with depth. In the case of sea water (specific gravity = 1.025), water pressure increases by 1 ATM (1.03kg/cm2) with each 10 meters (33 ft.) of depth. This watch makes use of the relationship between pressure and depth, using a pressure sensor to calculate the water pressure and then converting this data into depth readings.
