I've noticed that sometimes the heart stops flashing briefly.
• As long as the heart is flashing, the watch is receiving a clear signal from
the monitor. The communication system used in the Timex Fitness
Monitor is extremely robust, yet no system is perfect, and occasionally,
as in any radio system, there may be interference or some other brief
jamming of the signal. If this should occur, the watch will communicate
this to you first by suspending the flashing of the heart. Most often, the
problem resolves itself and the flashing resumes. If the interruption con-
tinues, the watch will alert you with one of the error messages described
below.
I see "COMM ERR" 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 monitors,
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 dash-
es in place of the heart rate.
This is the error message you will see if the watch is not receiving regular
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 dry. LIBERALLY moisten them and readjust the
chest transmitter if necessary.
• The battery in the chest transmitter may be weak and need replacing. See
below for instructions on battery replacement.

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

Assuming an hour a day usage, the battery life of the transmitter should
