External DC power operation

D Operating note

• DO NOT connect over 16 V DC directly into the
[DC IN] jack of the transceiver� The power source
voltage must be between 10�0 V ~ 16�0 V DC�
• DO NOT transmit at high power for a long period
of time� The transceiver becomes hot and it may
cause a burn�
• Use the optional CP-12L, CP-19R, or OPC-254L
when using the external DC power�
• Confi rm the correct polarity of the OPC-254L
supply connection� Connect the OPC-254L to an
external power source (user supplied)�
• Use an external DC-DC converter to connect the
transceiver through the optional CP-12L, CP-19R,
or OPC-254L to a 24 V DC power source� Ask
your dealer for details�
• Up to 5 W (approximately) of maximum output
power is possible when using the 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�
• When the external power is used, the Power Save
function (p� 11-33) is automatically turned OFF�
• Depending on the external power voltage,
