For the Nearest Repeater function to work, the GPS must be enabled. The ID-31A supports the use of either the internal GPS or user supplied external GPS.
By default, neither GPS is selected. To enable the internal GPS:
- MENU - GPS - GPS Set - GPS Select - Internal GPS
You may also want to set the Power Saving for the GPS
- MENU - GPS - GPS Set - GPS Select - Power Save - Auto
It may take a few minutes to acquire a valid signal. You should locate the radio so that it has a clear view of the sky. Once acquired, you can view the current information by choosing
- QUICK MENU - GPS Information
Once the signal has been acquired, you can now see the closest repeater
- Press and Hold the DR button for 1 sec. - Select FROM field - Select Center Blue Button - Near Repeater
