Acquiring Gps Signals; Changing The Fuses - Kenwood KNA-G620T Manuel D'installation

Acquiring GPS Signals

The fi rst time you turn on the KNA-G620T, you must wait while the system acquires satellite signals for the fi rst time. This process
could take up to several minutes. Ensure that your vehicle is outdoors in an open area, away from tall buildings and trees, for fastest
acquisition. After the system acquires satellites for the fi rst time, it will acquire satellites quickly each time thereafter.

Changing the Fuses

If you need to replace a fuse on the red or yellow wires, to prevent a short circuit, ensure that the wires are not touching. Then
replace the old fuse with a new 2 A fuse.
When replacing a fuse, use only a new fuse with the prescribed rating. Using a fuse with the wrong rating may cause damage to
your unit. To prevent short circuits, disconnect the wire harness before replacing a fuse.
