BATTERY CHARGING 3 N External DC power operation An optional cigarette lighter cable (CP-12L or CP-19R; for 12 V cigarette lighter socket) or external DC power cable (OPC-254L) can be used for external power operation. D Operating note • Power supply voltage must be between 10.0-16.0 V DC. NEVER CONNECT OVER 16 V DC directly into the [DC IN] jack of the transceiver. • BE SURE to use CP-12L, CP-19R or OPC-254L when connecting a regulated 12 V DC power supply. Use an external DC-DC converter to connect the transceiver through optional CP-12L, CP-19R or OPC-254L to a 24 V DC power source. • The voltage of the external power supply must be within 10-16 V DC when using either CP-12L, CP-19R or OPC254L, otherwise, use the battery pack. • Disconnect the power cables from the transceiver when not using it. Otherwise, the vehicle battery will become exhausted. • The power save function is deactivated automatically during external DC power operation. • CP-12L (Optional) 3 Transceiver to [DC IN] to cigarette lighter socket (12 V DC) • CP-19R (Optional) BP-217 • OPC-254L (Optional) to 12 V DC (power supply) Black: _ White: + NOTE: Up to 5 W (approx.) of maximum output power is available when using external DC power. However, when the supplied voltage exceeds 14 V, the built-in protection circuit activates to reduce the transmit output power to 2.5 W (approx.). 15
