1. Remove the chest strap from your body, and let it sit for at least five

straps that may be transmitting.
3. On the watch, repeatedly press the MODE button until HRM Setup
appears in the top line of the display.
4. Press and hold the HEART RATE button. The message HOLD TO PAIR
should appear for about two seconds, followed by the instructions
WEAR STRAP, then PRESS MODE TO PAIR WATCH WITH STRAP.
5. Press the MODE button. A message saying WAIT FOR BEEP should
appear. The watch is now searching for a chest strap with which to
pair.
6. Now pick up your chest strap and hold it firmly with your thumbs
touching the sensor pads that normally contact your chest. Rub your
thumbs back and forth across the sensor pads a few times. This
contact should be enough to start the strap transmitting.

reason the pairing fails, repeat the above steps immediately beginning
with step 4.
