The attached battery pack will not be charged while operating the transceiver if "Charging (Power ON)" is set to the factory default setting. If the setting is set to ON in the MENU screen, the battery pack can be charged. • The external DC power source voltage must be between 10~16 V, and the current capacity must be more than 2.5 A to charge the battery pack when operating. qqConnect the DC cable as shown to the right. wwPush [MENU] to enter the Menu screen. eeP ush D-pad() to select the root item (Function), and then push D-pad(Ent) to go to the next level. D-pad (Ent) () ( MENU > Function > Charging (Power ON)) rrRefer to the menu sequence shown directly above and push D-pad() to select, and then push Dpad(Ent) to enter, one or more times until the last screen is displayed. ttPush D-pad() to select "ON." • OFF : The transceiver cannot be charged when the power is ON. • ON : The transceiver can be charged even if the power is ON. Transceiver • CP-12L (Optional) to a cigarette lighter socket (12 V DC) • CP-19R (Optional) to [DC IN] BP-271 • OPC-254L (Optional) to a 12 V DC (power source) Black: _ White: + BE SURE to attach the battery pack before connecting the DC cable. • "Charging (Power ON)" setting screen TIP: When the transceiver power is ON, the battery icon sequentially shows and " " while charging, and the icon disappears when the battery pack is completely charged. NOTE: Up to 5 W (approximately) of maximum output power is possible when using external DC power. However, when the supply voltage exceeds 14 V, the built-in protection circuit activates to reduce the transmit output power to approximately 2.5 W. DDOperating note • The power source 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 a CP-12L, CP-19R or OPC-254L when connecting a regulated 12 V DC power source. Use an external DC-DC converter to connect the transceiv- er through an optional CP-12L, CP-19R or OPC-254L to a 24 V DC power source. • The voltage of the external power source must be between 10~16 V DC when using either CP-12L, CP19R or OPC-254L, 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 automatically deactivated when using an external DC power source. • Be sure to observe the correct polarity of the OPC254L supply connection. • When external power is used, the power save function is automatically turned OFF. • ID-51A/E's charging circuit may generate certain spurious signals; the S-meter appears, or noise may be heard. When you operate the transceiver while charging, and if you cannot receive signals correctly, set "Charging (Power ON)" in the MENU screen to OFF. 4-6
