3.7.3. Setting compass timeout
You can define how long the compass stays on after you have activated it. Reset the timeout
with any button press while using the compass.
After the timeout, the Suunto D6M returns to time or dive mode.
To set the timeout:
1. While in the compass display, keep [DOWN] pressed.
2. Press [DOWN] to scroll to Timeout and press [SELECT] .
3. Adjust the timeout time with [DOWN] or [UP] .
4. Press [MODE] to exit.
3.7.4. Setting bearing lock
A bearing is the angle between north and your target. In simple terms, it is the direction you
want to travel. Your heading, on the other hand, is your actual direction of travel.
The default bearing is North.
You can set a bearing lock to help you orientate yourself underwater and ensure you maintain
your direction of travel. For example, you can set a bearing lock for the direction to a reef
before leaving the boat.
The last locked bearing is stored and available the next time the compass is activated. In
DIVE mode, the locked bearings are also stored in the log. To lock a bearing:
1. With the compass active, hold the watch in front of you and turn yourself towards your
target.
2. Press [SELECT] to lock the current degree displayed on the watch as your bearing.
3. Press [SELECT] to clear the lock.
If, at any point, your bearing moves outside the compass display, right or left arrows appear to
show turn direction.
