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 to 12 to 14 V.
3
Insert the plug of the external power supply
in the EXT DC IN jack of the transceiver.
Cautions
z When you use the transceiver with the external power supply cable (E-DC-6) connected to an
external power supply, pay attention to the following:
z The power supply voltage must be between 12 V and 14 V.
z If the voltage exceeds 14 V, the high voltage protection function is activated to disable high-power
transmission. L3 (2.5 W) is selected automatically to reduce the transmission power. If the voltage
exceeds 16 V, malfunctions such as damage to the electric circuits of the transceiver may result.
Take extra care.
z 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.
z Use an external power supply having sufficient current capacity (3 A or more).
z If the transceiver is used with supplied antenna connected, the external power supply can
malfunction, resulting in a failure. If you use an external power supply, remove the supplied antenna
and connect an external antenna. Place the external power supply sufficiently away from the
transceiver.
z Use the transceiver at the minimum required transmission power level to prevent overheating.
z Do not continue transmission for a prolonged period. The transceiver may overheat, resulting in
malfunction or burn.
z If you operate the transceiver for 7 hours or longer, it is recommended that you remove the battery
pack and install the optional battery case (FBA-39).
z Recharging the fully-charged battery pack repeatedly can shorten its service life. Be extremely
careful not to do so when you operate the transceiver using an external power supply.
z While charging the battery pack, protect the transceiver from water.
z Charge the battery pack in a place where the ambient temperature is +5 °C to +35 °C (+41 °F to
+95 °F).
z If the terminal or electrode of the battery case is dirty, the transceiver may malfunction due to poor
contact, resulting in overheating or rupture. If the terminal or electrode gets dirty, clean it using a dry
cloth or cotton swab.
Tips
• The transceiver can be charged within approximately 5 hours using the external power
supply(approximately 8 hours to charge the optional battery pack FNB-102LI). If the battery pack is
charged with the transceiver turned on, the charging time increases slightly.
• The external power supply can be used with the battery case installed.
If you connect the transceiver to the external power supply with it turned off, "CONNECTED
TO EXTERNAL POWER" appears on the LCD, and about 20 seconds later "BATTERY NOT
INSTALLED" appears.
Preparation
Connect the external
antenna.
