Both the Suunto Smart Sensor module and chest strap should be rinsed with fresh water after
each use.

the chest strap connectors. Unsnap one side at a time.

tag for further washing instructions.
CAUTION: Do not machine wash the Suunto Smart Heart Rate Belt module. Machine

will wear out like any textile will and may need to be replaced when the heart rate reading
becomes unreliable. See 5.2. Troubleshooting

and your sports watch or mobile device. When not on wrist, keep the watch or mobile in front
of you or to one side in a pocket or on a belt.

If the Suunto Smart Heart Rate Belt does not seem to be sending heart rate data even without
obstructions, try any of the following:
1. Ensure the belt contact areas (electrodes) are wet and the belt Suunto logo is turned the
correct way.
2. Adjust the belt so that it fits tighter against your chest.
3. If your skin tends to remain dry during a workout, use electrode gel.
4. Check that Bluetooth is on in the device your belt is paired with.
5. Change the battery in the sensor and re-pair with your sports watch or mobile device.
If the Suunto Smart Heart Rate Belt seems to send incorrect data, try any of the following:

2. Pair the belt again with your Bluetooth
Ⓡ
Smart-enabled device.
3. Mashine wash the chest strap in 30°C.
