2.9Replacing the Battery

Hydra-AlertTMJr. uses Lithium CR2032 battery.

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 replacement, 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.
