Heart Rate Sensor

Speed + Distance Sensor

Watches are for more than keeping time. Digital technology gives
your watch the ability to display your heart rate or measure your
speed and distance traveled. These functions require the use of
external modules that transmit information wirelessly to your
watch. This booklet provides instructions for properly setting up,
operating and maintaining these devices. Look for the section that
is
appropriate for the type of device you have.

For information on using your watch, consult
the watch instruction booklet.

Warning

This is not a medical device and is not recommended for use
by persons with serious heart conditions. You should always
consult your physician before beginning or modifying an
exercise program.

Interference with the radio signal, poor contact between your skin
and the chest strap, and other factors may prevent accurate
transmission of heart rate data.

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

Heart Rate Monitor

How the Digital Heart Rate Monitor Works

The Heart Rate Monitor is a combination of a Heart Rate Sensor
and a sport watch. The Heart Rate Sensor attaches to your chest
and measures the electrical signals generated by the heart as it is
beating. Using this information, it then calculates your heart rate
and transmits it to your watch. You simply glance at the watch
during exercise/training to make sure you are in the appropriate
heart rate range to maintain or improve your fitness level.

How to Use the Digital Heart Rate Monitor

1. Wet the Heart Rate Sensor pads. THIS IS ESSENTIAL for proper
operation of the Heart Rate Monitor.

2. Put on the chest strap. Fasten the strap
snugly around your chest, just below
the breasts. Be sure the transmitter is
centered on the chest and is right side
up so the logo can be read by someone
facing you.

3. Start the Heart Rate Monitor: Refer to the
user manual for your watch for detailed
instructions on viewing heart rate data.

battery has been inserted correctly. Use a coin to open the
battery compartment cover (back of transmitter).

• Insert new battery (CR2032 or equivalent) with “

+”facing you.

• Push the reset button next to the battery. Use 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.

3. Activate the heart rate monitor function on the watch.

4. Within a few seconds, the heart symbol on the watch display
should begin flashing, indicating that the transmitter is active.
This confirms that the battery was installed correctly.
NOTE: A heart rate value does not need to appear on the
display during this test.

IF FLASHING HEART DOES NOT APPEAR ON WATCH:

• Press the reset switch in the battery compartment again and
replace the battery cover.

• Reinstall the battery, and repeat test procedure above.

Water Resistance

The Heart Rate Sensor withstands water pressure to 60 p.s.i. See
chart at end of booklet for equivalents. WARNING: The Heart Rate
Sensor will not display heart rate when operated under water.

Speed + Distance Sensor

How the Speed and Distance System Works

The Speed + Distance (S+D) Sensor acquires signals from orbiting
GPS (Global Positioning System) satellites to determine your position
and changes in position anywhere on the globe. This information
is transmitted wirelessly to your watch so that it can compute
your speed, pace and distance traveled. For additional information
on determining your speed and distance, see the instructions for
your watch.

About GPS Lock Times

• On first use, the S+D Sensor can take up to 5 minutes or even
longer to establish a link with the satellites. After that, the unit
typically needs only one minute.

• If you move hundreds of miles from the location where you last

used the S+D Sensor or if you leave the S+D Sensor powered up
indoors for long periods of time before going outdoors, the search
may take longer than expected.

• For shortest GPS lock times, try to minimize movement while
the indicator light is flashing red.

576_BOOKLET.qxd 5/6/04 3:07 PM Page 4

Operating the S+D Sensor

For best results, the Sensor needs a clear view of the sky.

• Press and hold the S+D SENSOR ON/OFF button to turn on the

receiver. You should be outdoors in an open area. If the button
light glows red immediately (continuously, not flashing), the bat­tery is exhausted to the point where GPS operation is not possi­ble and the battery must be replaced. The ON/OFF button on
the S+D Sensor will initially flash red while the S+D Sensor cal­culates its position relative to the GPS satellites. The text
“SEARCHING” may appear on the watch display if using a com­patible Timex® watch.

• The ON/OFF button will flash green when the S+D Sensor has

successfully acquired signals from the satellites. Speed and
distance information is now being transmitted to the watch (or
other device).

• To turn off the S+D Sensor, press and hold the S+D SENSOR
ON/OFF button for one second. The button will glow red while
you are holding the button and then go out, indicating that the
S+D Sensor has shut down.

• The S+D Sensor will shut itself off automatically if any of the
following events occur:

6

— The battery becomes exhausted.
— No motion is detected for 15 consecutive minutes.
— No GPS signals are detected for 15 consecutive minutes.

Wearing the Speed and Distance S+D Sensor

For best results, strap the S+D Sensor to your upper arm. You may
also clip it to your waist. Wear your watch so it is always within
1 meter (about 3 feet) of the S+D Sensor; for best results it should
be worn on the same arm as the Sensor. Any clothing worn over
the S+D Sensor must be dry and free of metal.

Wearing the S+D Sensor on your upper arm

• Make sure that the belt clip is
removed. To remove the belt
clip, grasp clip and gently pop
off. To replace clip line up tab on
clip with slot on Sensor and gen­tly pop clip on to unit.

• If the armband is not attached,
slide plastic attachment with hook and loop strap into the slot of
the S+D Sensor as shown in the
diagram.

• Loosen adjustable armband and wrap the Sensor around your
upper arm.

• Pull armband so that it snugly fits around your arm and fasten

Refer to the user manual for your watch for the procedure to
check the S+D Sensor’s battery level.

Replace batteries

• Use a small slotted screwdriver or coin to loosen the battery
hatch on the bottom of the S+D Sensor case by turning counter­clockwise.

• Remove the battery hatch.

• Remove old battery and insert one (1) new AA battery. Observe
the +/- markings inside the battery compartment to ensure the
new battery is properly aligned.

• Replace the battery hatch and tighten the cap by turning clock­wise. Do not over-tighten. Replace the belt clip if necessary.

Maintenance

Rinse the S+D Sensor and its strap in fresh water periodically to
avoid buildup of materials that can interfere with the measurement
of your speed and distance.

Resolving S+D Sensor Errors and Error Messages

PROBLEM

• The S+D Sensor cannot lock onto GPS satellites (ON/OFF button
never changes to flashing green).

• The GPS S+D Sensor loses signals from the satellites during use.
The watch may display a message that the GPS signal is weak.

SOLUTION

• Move to a more open outdoor area.

• Move away from metal objects.

• Replace the battery in the S+D Sensor.

NOTE: The system can maintain accuracy for short periods when
GPS signals are lost.

PROBLEM

• Watch displays FATAL GPS ERROR message.

SOLUTION

• The S+D Sensor is damaged; contact Timex Customer Service.

S+D Sensor Battery Life and Replacement

The battery in the S+D Sensor will last approximately 12 hours.
