BATTERY CHARGING

■ External DC power operation

An optional CP-12L or CP-19R cigarette lighter cable,
for a 12 V cigarette lighter socket, or an OPC-254L ex-
ternal DC power cable can be used for external power.
The attached battery pack will not be charged while op-
erating 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 supply 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.
Connect the DC cable as shown to the right.

• OFF : The transceiver cannot be charged when the power
is ON.
• ON : The transceiver can be charged even if the power
is ON.
When the transceiver power is ON, the battery icon
sequentially shows "
while charging, and the icon disappears when the
battery pack is completely charged.
D Operating note
• The 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 a CP-12L, CP-19R or OPC-254L
when connecting a regulated 12
Use an external DC-DC converter to connect the transceiv-
er through an optional CP-12L, CP-19R or OPC-254L to a
V DC power source.

• The voltage of the external power supply must be
between 10–16 V DC when using either CP-12L, CP-
19R 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.

NOTE: Up to 5 W (approximately) of maximum out-
put 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 trans-
mit output power to approximately 2.5 W.
• The power save function is automatically deactivated
when using an external DC power source.
• Be sure to observe the correct polarity of the OPC-
254L supply connection.
• When external power is used, the power save func-
tion 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.
