Before Operating the Transceiver
Caution
The use of a transceiver in the following places may be prohibited.
• Aboard aircraft •In airports •In ports •Within or near the operating area of
business wireless stations or their relay stations.
Before using the transceiver in any of the above places, obtain any necessary
permission from the proper authorities, and be mindful of local laws that govern
amateur radio operation.
■Points to Note when Using an External Power Supply
• Use a 4.5V-16.0 DC external power source.
• When connecting the power supply to the transceiver, use the optional DC
cable for base stations (EDC-37). Connect the cable to the DC jack on the side
of the transceiver.
• When power is supplied from the cigarette lighter socket of a car, use the
cigarette lighter cable (EDC-43) or the cigarette lighter cable with filter (EDC-
36).
Use the cigarette lighter cable with filter (EDC-36) during mobile operation
to help prevent noise.
• Turn the transceiver's power off when connecting or disconnecting the DC
cable.

Caution
•The battery pack is not charged when shipped. It must be charged before using.
•It takes a maximum of 10 hours to charge the battery pack with the EDC-93
(120V) / EDC-94 (230V)(EBP-52N / EBP-53N) and about 30 hours with the
EBP-54.
•Charging should be conducted within a temperature range of 0 to 40˚C.
(32-104˚F)
•Do not convert or dismantle the battery pack and do not place it in fire or water.
Such practices are dangerous. Never short-circuit the battery pack terminals, as
this can cause damage to the equipment or lead to overheating the battery, which
could cause burns. Unnecessary prolonged charging (overcharging) can
deteriorate battery performance.
•The battery pack should be stored in a dry place where the temperature range is
-20˚C to -45˚C (-4˚F to +113˚F).
Temperatures outside this range can cause battery liquid leakage. Exposure
to prolonged high humidity can cause corrosion of metal components.
•Normally, the battery pack can be charged up to 500 times. However, the battery
pack can be considered dead if usable time drops off markedly in spite of charging
the pack for the recommended time. When this happens, a new pack should be
used.
•To protect the environment, do not dispose of the used battery pack improperly.
Check with your local solid waste officials for details on recycling the battery
pack for proper disposal in your area.
•To charge the battery pack, mount it on the transceiver, connect 13.8VDC to the
DC power supply jack and set the unit's battery charging function ON in the
Setting mode.
1-2-3 Battery Pack (Option)
1. Attaching the battery pack:
Align the grooves on the battery pack
with the rib on the transceiver, and
push in the direction of the arrow
until it clicks.
2. Detaching the battery pack:
Push down the catches at the bottom
of the transceiver, and slide the
battery pack off in the direction of
the arrow.

1-3 Battery Level Indicator
•Battery charge level may change in
relation to ambient air temperature or
the amount of use.
•Even if the charge indicator appears
to show the need for charging or
replacing batteries, the transceiver
may still be used for reception or low
output transmission.
•Modify the battery type setting in the
Setting mode when the battery pack
type is changed.
1-4 Loading Batteries
1.Load three (3) commercially
available AA alkaline batteries in the
battery case (EDH-31).
Set the batteries in the battery case in
the +/- orientation marked at the
bottom of the case.
2. Attach the battery case in the same
method of the battery pack (page3).
Caution
•Manganese batteries are not recommended as they may decrease the
transmission output level.
•Be sure to observe proper orientation of the batteries polarity (+ -).
•Switch off the battery transceiver's charge function when dry cell batteries are
used.
Charge Level
When the charge level becomes low,
an empty battery mark appears.
Charge (or replace) the battery.
