CAUTION

Diving at High Altitudes or in Fresh Water

• Do not use this watch when diving at high altitudes more than 4000 m above

sea level since it is unable to measure water depth correctly under these

conditions.

• When diving at high altitudes or in fresh water, only use the watch after

receiving special safety training.

• Since this watch displays water depth by converting on the basis of sea

water (specific gravity: 1.025), the water depth displayed when diving in fresh

water is actually 2.5% deeper. For example, when the watch displays a

water depth of 20 m in fresh water, the actual water depth is 20 x 1.025 =

20.5 m.

• Avoid ascending too rapidly. Attempting to ascend at an excessively rapid

rate can have detrimental effects on the body such as causing the bends.

Observe a safe ascent rate at all times.

• Never attempt to operate the crown underwater. This can cause a malfunction

due to impaired water resistance.

• Caution is required since the alarm may be difficult to hear due to breathing

noise underwater.

• Allow a suitable rest period after diving while referring to the surface mode

(measurement of elapsed time after diving).

• Rinse off any sea water, mud or sand adhering to the watch with fresh water

after confirming that the crown is screwed in and locked in position, and then

wipe off any excess moisture with a dry cloth.

• Do not attempt to remove any debris or dirt trapped in the sensor by remov-

ing the sensor cover or poking with a sharp object. If debris should happen

to enter the sensor, rinse with fresh water. When debris cannot be removed

by rinsing, consult a Citizen Service Center.
