Troubleshooting
The current speed / heart rate cannot be measured.
Check that the clearance between the sensor and magnet is
not too large. (Clearance: within 3 mm)
Check that the magnet passes through the sensor zone cor-
rectly.
Adjust the positions of the magnet and sensor.
Is the heart rate sensor attached securely to your body?
Adjust the electrode pad to have a good contact with the
body.
Is the electrode pad overly worn and damaged after long use?
Replace it with a new HR strap.
Is there any problem in searching the sensor ID?
Search the sensor ID according to the procedure speci-
fied in the section “Changing the computer setting /
Searching for sensor ID” (Page 8).
Does the computer or sensor indicate when to replace the bat-
tery?
Replace with new batteries according to the procedure
specified in the section “Replacing the battery.”
Nothing is displayed by pressing the button.
Replace the computer battery according to the procedure
specified in the section “Replacing the battery”.
Incorrect data appear.
Restart according to the procedure specified in the section

(The maximum speed is too high, etc.)
Are there any objects emitting electromagnetic waves (railway
tracks, transmitting stations for television, Wi-Fi environment, etc.)
nearby?
Keep the unit away from any object that may be the cause.
Perform the resetting operation in the case of invalid data.
