Connecting to an External Power Supply Using a Power Cable

(USA/EXP version only)
The optional power cable (E-DC-6) allows the transceiver to be connected to an external
power supply.
1
Turn off the transceiver.
2
Connect the optional external power supply
cable (E-DC-6) to an external power supply.
Remarks
• Connect the red/black wire or white/red
wire to the positive (+) terminal of the
external power supply and the black wire
to the negative (−) terminal.
• Set the voltage of the external power
supply at 12 to 14 V.
3
Insert the plug of the external power supply
into the EXT DC IN jack of the transceiver.
Cautions
y When using the transceiver with the external power supply cable (E-DC-6) connected to an external
power supply, pay attention to the following:
• The power supply voltage must be between 12 V and 14 V.
If the voltage exceeds 16 V, malfunctions and damage to the electric circuits of the transceiver may
result. Take extra care.
• Connect the red/black wire or white/black wire of the external power supply cable (E-DC-6) to the
positive (+) terminal of the external power supply and the black wire to the negative (−) terminal.
• Use an external power supply having sufficient current capacity (3 A or more).
• If the transceiver is used with the supplied antenna connected, the transmit RF may interfere with
the external power supply, resulting in malfunction or failure. When using an external power supply,
remove the supplied antenna and connect an external antenna. Place the external power supply
sufficiently away from the transceiver to avoid RF interference.
y Use the transceiver at the minimum required transmission power level to prevent overheating.
y Do not continue transmitting for a prolonged period. The transceiver may overheat, resulting in
malfunction or a burn injury.
y To operate the transceiver for 7 hours or longer, it is recommended that the battery pack be replaced
with the optional battery case (FBA-39).
y Recharging the fully-charged battery pack repeatedly can shorten its service life. Be extremely careful
not to continually recharge the battery when operating the transceiver using an external power supply.
y While charging the battery pack, protect the transceiver from water.
y Charge the battery pack in a place where the ambient temperature is +5 °C to +35 °C (+41 °F to +95
°F).
y If the terminals or electrodes of the battery pack are dirty, the transceiver may malfunction due to poor
contact, resulting in overheating or rupture. If the terminals or electrodes get dirty, clean them using
a dry cloth or cotton swab.
Preparing the Battery Pack/External Power Supply
