SUUNTO t1c - Manual (Page 23)

7 TROUBLESHOOTING
Suunto t1/t1c uses coded transmission to prevent reading disturbances. However,
exercising near overhead power lines or magnetic or electronic devices may cause
interference with the signal.
If you lose the signal, try the following:
● Exit and then re-enter TRAINING mode.
● Check that you are wearing the belt correctly.
● Check that the electrode areas of the belt are moist.
● Move away from any potential sources of interference.
● Replace the battery (of the belt and/or wristop) if problems persist.
● Check the code; if CODE NOT FOUND is shown, re-pair the belt.
