Acquiring GPS Signals The first time you turn on the KNA-G610, you must wait while the system acquires satellite signals for the first 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 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, to prevent a short circuit, ensure that the wires are not touching. Then replace the old fuse with a new 2 A fuse. n CAUTION 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.
