3.6.3. GPS fix
The selected GPS fix interval determines how often your Suunto X9 establishes a satellite connection and how often it stores data in the memory. This in turn affects the battery life. To select a GPS fix:
1. In the Set menu, select GPS fix with UP/DOWN and press ENTER. The fix interval field is activated.
2. Select a suitable fix interval with UP/DOWN and press
ENTER.
When the Navigate function is on, your Suunto X9 uses the following settings depending on the chosen fix interval.
