D. For safe usage

[Make sure you read this caution]

CAUTION:

1. Items to check for safe usage

a. The depth display of this watch is up to 80m (260ft). Although this watch has water resistance up to 80m (260ft), for safe diving we recommend that you stay shallower than 30 metres (100ft) [sports diving].

b. The water depth meter in this watch is set according to the sea water standard (1.025 gravity)

In case you use the watch in fresh water, i.e., you need to make a conversion.

[Example]

When the watch is 80m (260ft) deep, in the case of sea water it displays 80m (260ft), but when in fresh water, it displays 78m (253ft); shallower than what it really is.

c. Avoid descending too rapidly. In order to get an accurate depth reading, slow down the descent, or stop.

d. Avoid ascending too rapidly.

If you ascend at a speed greater than 1.5m (5ft) per 5 secs (D201/D207). /0.9m (3ft) per 6 secs (D202/D208).

18m (60ft) per minute (D201/D207) /9m (30ft) per minute (D202/D208) according to the U.S. navy diving manual, then the ascending speed warning function will operate. The dot display changes to “SLOW” display and an alarm will sound.

Please maintain a safe ascending speed. Slow down your ascent or stop in order to get an accurate depth reading.

As rapid ascending is hazardous to the human body, sometimes causing the bends, always avoid it.

*The new regulation of the U.S. Navy diving manual is executed in 1993, changing the Surface Speed Warning at the rate of 9m/min. from 18m/min.

e. Do not use the watch in places where it is exposed to large changes of air pressure or temperature.

The watch will automatically check for unusual air pressure, while in various normal modes (time and calendar mode / surface mode / log mode / alarm mode). If any abnormality is detected, the dot display will alternate between dot display and “ERR” display. When this happens, the water depth cannot be measured. If the “ERR” display disappears, the watch can be used normally.

✩When boarding a plane

When exposed to sudden pressure change (pressurisation) as in the inside of an aeroplane, if applicable, if the water sensor is touched with a finger or moistened, the watch may change to dive mode. If it changes to dive mode, dry the water sensor, and cancel dive mode by holding down button M for more than 2 seconds.

f. We recommend that you change the battery as early as possible.

The life of the battery in this watch is about 3 years after a new battery is installed. (Please look up S. [Battery] for the conditions of usage). However, the life of the battery changes a lot depending on the frequency of use of various functions. In order to enjoy safe diving, we recommend that you change the battery ahead of time.
