Care & Maintenance

Watch Battery Replacement

When the battery of the watch is running low, the display or INDIGLO
night-light will dim. This watch uses a CR2032 lithium battery.
To avoid the possibility of permanently damaging the watch, TIMEX
STRONGLY RECOMMENDS TAKING YOUR HEART RATE MONITOR WATCH TO
A LOCAL RETAILER OR JEWELER TO HAVE THE BATTERY REPLACED.
INDIGLO® night-light

®
Patent Numbers 4,527,096 and 4,775,964) electroluminescent technology
illuminates the watch display at night and in low light conditions.

BUTTONS UNDER WATER.

Heart Rate Sensor Strap Maintenance

Rinse Heart Rate Sensor and strap in fresh water to avoid build up of
materials that can interfere with the measurement of your heart rate.

Transmitter Battery Life and Replacement

Battery life of the transmitter should exceed two years, based upon using
it an hour a day. Greater usage will shorten the battery life. Replace
transmitter battery when any of the following occur:
• The watch no longer receives heart rate information from the chest
transmitter when properly worn on the chest.
• Error messages (COMM ERR, SIGNAL LOST) appear with increased
frequency on the display.

Battery Replacement

NOTE: You'll need to have a device (such as a watch) capable of displaying
heart rate information to verify that the new battery has been inserted
correctly. Use a coin to open the battery compartment cover (back of
sensor).
• Insert new battery (CR2032 or equivalent) with "+" facing you.
