When the watch displays “
LOW BATT
” (as in the figure below), the battery in
your watch needs to be replaced. To maintain its water resistance, professional
battery replacement service is advised. Improper battery replacement or service
will void the warranty. In the case of self replace
ment, removal of the old battery
should be documented in detail to ensure proper replacement of new battery, position
of contacts, and O-ring line-up. To maintain the watch’s water resistance, it is a good
idea to smear a small drop of silicone lubricant spray on the O-ring.
Note:
After the first low battery warning comes on for 15 minutes, the EL,
Humidity & Temperature features will be turned off to conserve the
battery power.
