While recording an exercise, you can lock the buttons and the screen by pressing the crown and toggle Lock screen on. Once locked, you cannot perform any action that requires button interaction (create laps, pause/end exercise etc.) or change the display view.
To unlock the buttons and the screen, long press the upper and the lower button simultaneously.
If you want to lock the touch screen but still use the buttons while exercising, toggle the touch screen option off in the exercise settings before you start recording the exercise.
When you are not recording an exercise, the screen becomes inactive and dims after a certain time of inactivity. To activate the screen, press any button.
See Display settings for information on the screen behavior.
You can check details of your watch software and hardware from the settings under General » About.
You can set time and date during the initial startup of your watch. After this, your watch uses GPS time to correct any offset.
Once you have paired with Suunto app, your watch gets updated time, date, time zone and daylight-saving time from mobile devices.
In the Settings, under General » Time / Date, tap Auto time update to toggle the feature on and off.
You can manually adjust time and date from the settings under General » Time / Date where you can also change time and date formats.
In addition to the main time, you can use dual time to follow the time at a different location, for example, when you are traveling. Under General » Time / Date, tap Dual time to set the time zone by selecting a location.
You can change your watch language and select the region where you live from the settings under General » Language.
You can change the unit system of your watch from the settings under General » Unit system.
You can use the metric or the imperial system. Once you select one, all the data on your watch will be displayed in the units of the selected system.
Your watch includes a power saving option that turns off all vibration and reduces display brightness and the frequency of daily HR measurement to extend battery life during normal daily use. For power saving options while recording activities, see Battery power management.
Enable/disable power saving from the settings under General » Power saving or in the Control panel.
Power saving is automatically enabled when the battery level reaches 10%.
All Suunto watches have two types of reset available to address different issues:
Performing a restart on your watch might help with the following situations:
The restart will end and save any active exercise. Under normal circumstances, the exercise data will not be lost. On rare occasions, a soft reset may cause memory corruption issues.
You can restart your watch via the Settings. Select General and scroll down to Restart. Confirm your choice by pressing the upper button.
If you cannot access the watch menu, press and hold the upper button for 10 seconds and release it to restart the watch.
There are specific circumstances under which the soft reset might not solve the issue and the second type of reset may be performed. If the above has not helped with the issue you were aiming to solve; the hard reset might help.
The factory reset will restore your watch to the default values. It will erase all data from your watch, including exercise data, personal data and settings that have not been synced to Suunto app. After a hard reset, you must go through the initial setup of your Suunto watch.
Performing a factory reset on your watch may be performed in the following situations:
The factory reset of your watch is done via the Settings on your watch. Select General, scroll down to Reset settings and select it. Initiate the reset by pressing the upper button. All data on your watch will be deleted during the reset.
The factory reset deletes the previous pairing information your watch might have had. To start the pairing process with the Suunto app again, we recommend you delete the previous pairing from the Suunto app and your phone's Bluetooth - under Paired devices.
Both presented scenarios are to be performed only for emergencies. You should not perform them regularly. If any issue persists, we recommend you either contact our Customer Support or send your watch to one of your authorized service centers.
If you don't want to use your watch for a while, you can power it off. Go to Settings, select General and scroll down to Power off. Confirm your choice by pressing the upper button.
To wake up the watch, keep the crown pressed.
