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 dis-
play 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.
