3.2. Heart rate signal troubleshooting
Although the heart rate transmitterbelt can be used with gym equipment like treadmills and training
bikes, usingthe belt near overheadpower lines orsome magnetic or electronicdevices may cause
interference with the belt's signal.
Although rare, it is possible that someone with the same heart rate transmitter belt code happens
to be training close to you causing interference with your heart rate readings. In the event of such
interference, check the belt codes by long pressing the BACK button in Training mode. You will
see the belt code in the middle of the display for few seconds. If you have matching codes, move
further off from your training partner. If the interference continues, you should remove the battery
from one of the belts and reinstall it. The belt will then automatically search a new code from 1 to
29.
If you lose the signal, try the following steps to fix the problem.
Exit and then re-enter Training mode.
Make sure that you are wearing the heart rate transmitter belt correctly. (See Section 3.1.
Putting on the heart rate transmitter belt)
Ensure that the electrode area on the back of the belt is slightly wet.
Move away from any potential source of interference.
If you have been using the belt for some time,the battery may need changing. For instructions
on how to change the transmitter belt's battery, see Section 7.3.2. Replacing the battery of the
heart rate belt.
