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 measure-
ment 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.
Heart Rate Monitor 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 transmitter battery should be replaced when any of the following
things occur:
• The watch no longer receives heart rate information from the chest trans-
mitter when properly worn on the chest.
• Error messages (COMM ERR, SIGNAL LOST) 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 straight-
ened paper clip will help you do this) before installing the battery cover.
A quick test of the unit should be performed after changing the battery:
1. Move away from any possible sources of electrical or radio interference.
2. Liberally moisten the sensor pads and put the units on your chest,
securely against your skin.
I see “Check Strap Fit” appear on the display, then the watch displays
dashes in place of the heart rate.
This error message will be displayed if the watch is receiving a signal
from the transmitter but is also detecting interference from an external
source.
Move away from any radio frequency devices, other heart rate moni-
tors, fitness equipment or large metal objects (such as automobiles).
The watch may be receiving a competing signal from another Timex
Fitness Monitor. For best results, try to maintain at least six feet
between you and another Timex Fitness Monitor user.
The battery in the chest transmitter may be weak and need replacing.
See below for instructions on battery replacement.
I see “SIGNAL LOST” appear on the display, then the watch displays
dashes in place of the heart rate.
This is the error message you will see if the watch is not receiving reg-
ular heart rate updates from the chest unit. However, as long as the
chest unit is on the chest, the sensor pads are wet and the battery in
the transmitter is not weak, the watch will usually recover from this
type of error without intervention on your part. In cases where the
watch does not recover a heart rate reading, the following items may
help you troubleshoot your problem.
The sensor pads on the chest transmitter may have lost contact with your
chest for a few seconds. Be sure the transmitter is snug on your body.
The sensor pads may be very dry. LIBERALLY moisten them and read-
just the chest transmitter if necessary.
The battery in the chest transmitter may be weak and need replacing.
See below for instructions on battery replacement.
