Acquiring GPS Signals

The first time you turn on the KNA-G520, you must wait while the system acquires satellite signals for the first time. This process
could take up to several minutes. Make sure your vehicle is outdoors in an open area away from tall buildings and trees for fastest
acquisition. After the system acquires satellites for the first 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, make sure the wires are not touching to prevent a short circuit. Then replace
the old fuse with a new 2 Amp fuse.
Caution
When replacing a fuse, use only a new fuse with the prescribed rating. Using a fuse with the wrong rating may cause your unit to
malfunction. Disconnect the wiring harness before replacing a fuse to prevent short circuits.
