ACQUIRING HEART RATE (WEARING THE CHEST BELT)
ACQUIRING HEART RATE: FINGER TOUCH
Heart rate may be acquired from any operating mode (not in any Setting Sequence).
1. With the watch attached to your wrist, TOUCH & HOLD the HEART RATE SENSOR (anywhere on the
metal top plate) with one finger.
NOTE: If Heart Rate Sensor is accidentally touched, the watch will automatically attempt to acquire heart rate. If no
heart rate is detected, watch will resume operating mode in approximately 10 seconds. This will not interfere with any
timing functions in progress.
NOTE: You may exit Heart Rate mode at any time by Pressing the Mode, Start/Stop or Reset key.
2. Continue TOUCHING & HOLDING until heart rate displays.
3. Once Heart Rate is acquired, RELEASE THE SENSORS. Heart Rate will continue to display for a
period of approximately 10 seconds.
4. If trouble acquiring heart rate, moisten the underside of the watch case (so contact between the
wrist and watch is ensured). To activate heart rate, the watch’s back plate must come into direct
contact with your skin, while your fingertip is touching the top case.
See p.26 for more troubleshooting details.
ACQUIRING HEART RATE: WEARING THE CHEST STRAP TRANSMITTER
The Chest Strap Transmitter provides constant heart rate information throughout the duration of your
workout. To ensure a proper heart rate display, the chest transmitter must be properly adjusted. Snap
the plastic tabs at the end of the elastic belt into the holes at the end of the transmitter and adjust the
strap so that the transmitter fits tightly below the pectoral muscles, as shown in the drawing.
NOTE: Users with significant chest hair may have a problem obtaining contact between the transmitter electrodes and
their skin, resulting in poor performance. It may be necessary for these individuals to shave the area of their chest
beneath the transmitter.
NOTE: In dry and cold climates it may take a few minutes for a layer of perspiration to form between the chest strap
and the skin. Moistening the electrodes with saliva or ECG conductive gel can speed up this process.

NOTE: DEACTIVATING TOUCH HEART RATE
If you wish to deactivate the touch heart rate feature, in Time mode, PRESS
& HOLD the RESET/LOCK button for 3 seconds. A lock icon will appear on the
screen indicating the feature is deactivated. Hold the button again for 3 seconds
to activate the feature.
NOTE: DISPLAYING HR ON THE WATCH
Once the chest strap is correctly in place, you must toggle the watch
display to the HEART RATE/CHRNOGRAPH mode and PRESS the
START/STOP button. The timer will begin running, and the watch
will begin displaying heart rate from the strap after a slight delay.
See p.18 for more details.
