Transmitter Battery Life
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.
Transmitter 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.
• Push the reset button next to the battery by using a toothpick or
straightened paper clip.
• Reinstall battery cover.
• Perform quick test of the unit:
1. Move away from sources of electrical or radio interference.
2. Liberally moisten the Heart Rate Sensor pads and put the chest strap
around your chest, securely against your skin.

Water Resistance
Your 100 Meter Water Resistant watch withstands water pressure to
140 p.s.i.a. (equals immersion to 328 feet below sea level).
The watch is only water-resistant as long as the lens, pushbuttons, and
case remain intact.
Timex recommends rinsing your wrist monitor with fresh water after
exposure to salt water.
WARNING: TO MAINTAIN WATER-RESISTANCE, DO NOT PRESS ANY
BUTTONS UNDER WATER.
Heart Rate Sensor and 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.
The FLEX TECH™ strap can be machine washed in cold water with the
transmitter removed. Hang it to dry away from direct heat or sunlight. Dry
the metal contacts on the transmitter and the strap to prevent corrosion.
