• If you want to stop monitoring data from your Bodylink™ sen-
sors, hold the DISPLAY button down until the message HOLD
TO SHUT OFF RCVR is displayed on the watch display. Continue
holding the DISPLAY button for a few more seconds; the watch
will beep indicating that the radio link between the watch and
the sensors has been shut down.
TIP: If you are already viewing data from one sensor, for exam-
ple, the Heart Rate Sensor, and you wish to also view data from
the Speed +Distance Sensor, simply press and hold the DISPLAY
button until the watch emits a short beep and the antenna icon
begins flashing.The watch is now searching for a second
Bodylink™ sensor. When it detects this second device, the
antenna icon will stop flashing and the display may change to
a new format that includes the new information. Press and
release the DISPLAY button (as detailed previously) to view

Sensors, the watch may display informational messages to com-

SEARCHING (Speed + Distance) – The Speed + Distance Sensor
has not yet detected enough GPS satellites to calculate your cur-
rent position, speed and distance. You will not be able to view
speed, pace or distance information until the Speed + Distance
Sensor locks to a sufficient number of GPS satellites.
WEAK GPS SIGNAL (Speed + Distance) – The Speed + Distance
Sensor has lost its link with the GPS satellites. This message will
appear when the Sensor no longer has a clear view of the sky,
such as under a dense forest canopy or inside a building; move
to a more open area as soon as you can.
NOTE: Both the Sensor and the watch employ techniques to
maintain reasonable distance accuracy during these periods
when GPS tracking is temporarily lost or when the radio link is
temporarily interrupted.
NO DATA FROM HRM (GPS) – The watch is not receiving data
from the indicated Sensor. Ensure that the Sensor is not more
than 3 ft. (1 m) away from the watch and that it is powered up
and functional.
The watch will attempt to “find” the Sensor after this message
has been displayed. It is possible that the watch may inadvertently
lock to another sensor nearby and not necessarily yours; there-
