Note: This article applies for Suunto 3 Fitness, Suunto 9 and Suunto Spartan Collection watches.
There are two resets available for your Suunto 3 Fitness, Suunto 9 or Suunto Spartan watch if it is not functioning properly.
Both resets are only for emergency situations and should not be performed on a regular basis. If the malfunction persists, please bring your watch to a Suunto Service Center.
A restart may help if
- device is not responding to button presses, taps, or swipes (touch screen is not working).
- display is frozen or blank.
- display is frozen in boot mode (display shows a downward facing arrow - "arrow down" - symbol).
- no vibration e.g. during button presses.
- watch functionalities are not working as expected e.g. no wrist heart rate data is recorded (optical heart rate LED lights are not blinking), compass is not calibrating.
- step counter is not counting daily steps (please note, recorded steps may be shown with a delay).
- SuuntoLink is not recognizing the device.
Note: The reboot will end and save active exercises. Under normal circumstances no exercise data will be lost.
In rare occasions a soft reset may cause memory corruption issues.
To soft reset:
Press the right upper button for more than 12 seconds and then release it for:
- Suunto 9
- Spartan Trainer

If the soft reset does not fix the issue, we recommend performing a factory reset.
