Besure to use a 12 V vehicle battery that has sufficientcurrent capacity. If the current to the transceiver isinsufficient, the display may darken during transmission,or transmit output power may drop excessively.1 Route the DC power cable supplied with thetransceiver directly to the vehicle’s battery terminalsusing the shortest path from the transceiver.• If using a noise filter, it should be installed with aninsulator to prevent it from touching metal on thevehicle.• It is not recommended to use the cigarette lightersocket since some cigarette lighter sockets introducean unacceptable voltage drop.• If the power cable must be routed through a hole in thevehicle chassis or body, for example in the firewall atthe front of the passenger compartment, use a rubbergrommet to protect the cable from abrasion.Dismantle the fuse holder to pass the cable throughthe firewall.• The entire length of the cable must be dressed so it isisolated from heat and moisture.2 After the cable is in place, wind heat-resistant tapearound the fuse holder to protect it from moisture.Tie down the full run of cable.3 To prevent the risk of short circuits, disconnect otherwiring from the negative (–) battery terminal beforeconnecting the transceiver.4 Confirm the correct polarity of the connections, andattach the power cable to the battery terminals; redconnects to the positive (+) terminal, black connectsto the negative (–) terminal.• Use the full length of the cable without cutting offexcess even if the cable is longer than required. Inparticular, never remove the fuse holders from thecable.5 Reconnect any wiring removed from the negativeterminal.6 Connect the DC power cable to the transceiver’spower supply connector.• Press the connectors firmly together until the lockingtab clicks.RedBlackFuse holderFuse holderPressfirmly.
