18. Low Battery Warning Function

When the battery of the watch approaches the end of its service life, the

second hand begins to move at two-second intervals (the second hand

advances by two increments in two seconds). When this happens, have

the battery replaced as soon as possible.

The functions of the watch are restricted according to the conditions described

below when the low battery warning function has been activated.

• Alarm and confirmation tones do not sound.

• Temperature cannot be measured in the time mode.

• The watch cannot be switched to the water depth mea-

surement mode (including the preliminary dive display).

When the low battery warning function is activated during

measurement of water depth, although measurement of

water depth continues until completion of that dive, the

depth alarm and dive time alarm do not sound.

• The watch cannot be switched to the altitude measure-

ment mode. When the low battery warning function is

activated during continuous altitude measurement, the

watch switches to fixed duration altitude measurement.
