Watch Maintenance and Warranty
Maintenance
The Heart Rate Monitor transmitter and its strap should be rinsed in fresh
water to avoid the build-up of materials that can interfere with the
measurement of your heart rate. The Fitness System watch does not need
to be rinsed.
Watch Battery Replacement
To avoid the possibility of permanently damaging the watch, TIMEX
STRONGLY RECOMMENDS TAKING YOUR WATCH TO A LOCAL RETAILER
OR JEWELER TO HAVE THE BATTERY REPLACED.
HRM Transmitter Battery Life and Replacement
Assuming an hour-a-day usage, the battery life of the transmitter should
exceed two years. Greater usage will shorten the battery life. The battery
should be replaced when any of the following occurs:
• The watch no longer receives heart rate information from the chest
transmitter when properly worn on the chest.
• Error messages begin to appear with increased frequency on the display.
Turn the unit over and use a coin to open the battery compartment cover.
Replace the battery, making sure the “+” is facing you when you insert the
new one. Push the reset button next to the battery (a toothpick or
straightened paper clip will help you do this) before replacing the battery
cover.
■ You Reach the Mid-Point of the Race: You have been running the race
comfortably in your target heart rate zone and the timer counts down to
zero.
• 30-Lap Model: TIMER Mode automatically launches CHRONO
Mode, which was the mode selected in the step above to follow the
TIMER Mode countdown. The previously configured display
format for CHRONO and HEART RATE information appears. You
step up your pace in the second half. As you cross the finish line,
press STOP/RESET/SET (DONE) to stop CHRONO Mode timing.
• Fitness Model: Press any button to disable the Timer alert and
step up your pace at the 16-minute point of the race. As you cross
the finish line, press START/STOP to stop TIMING Mode.
■ Reviewing Your Heart Rate Data and Race Times: Later you can scroll
through your accumulated fitness data for the race.
• To review your HRM data and race times, go to REVIEW. Press
START/SPLIT (+) or START/STOP (+) to advance through your HRM
and race data, or press HEART RATE (-) to cycle backwards.
NOTE: CHRONO Mode must be reset to zero to be automatically
launched by TIMER Mode.
