* For safety’s sake, the watch will also undergo a strict check at the time of battery replacement. In
addition to battery replacement, water resistant quality of the watch and the depth measurement
function will be checked. The gasket will be replaced with a new one if necessary. Therefore, it
will take approximately 10 days before the watch is returned to you, and the checking may be made
at cost.
* The battery life may be less than 2 years if the alarm is used more than 15 seconds a day, and/or
the depth measurement function more than 50 times a year, one hour per dive.
* When the battery is replaced with a new one, or when it runs down, the log data will be erased from
memory.
WARNING
Do not remove the battery from the watch.
If it is necessary to take out the battery, keep it out of the reach of children. If
a child swallows it, consult a doctor immediately.
Never short-circuit, heat or otherwise tamper with the battery, and never
expose it to fire. The battery may burst, become very hot or catch fire.
The battery is not rechargeable. Never attempt to recharge it, as this may cause
battery leakage or damage to the battery.
