Before Operating the Transceiver
Attention
• Do not open the case or touch the interior components.
Tampering can damage the equipment.
• Do not expose the transceiver to direct sunlight, dusty places
or place it near sources of heat.
• Keep the transceiver away from TVs, tuners or other
equipment if it interferes with reception.
• Securely connect the antenna included with the transceiver.
• When transmitting for a long time, the transceiver can
overheat.
• Turn the power off immediately if the transceiver emits smoke
or strange odors.
Ensure that the transceiver is safe, then bring it to the nearest
Alinco Service Center.
Points to Note Before Transmitting
Many wireless stations use frequencies adjacent to the ham
bands for business purposes.
Be mindful when transmitting near them.
Even when amateur stations obey regulations, unexpected
interference can occur.
Pay sufficient attention during mobile operation.
Caution
The use of a transceiver in the following places may be
prohibited:
• Aboard aircraft
• In airports
• In shipping ports
• Within or near the operating area of business wireless
stations or their relay stations.
Before using in any of the above places, obtain any
necessary permissions 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 regulated 3.7V - 6.0V DC external power supply.
• To charge the battery or operate the transceiver using AC
power, use AC adaptor (EDC-126 or EDC-128 depending on
the version*).
• When power is supplied from the cigarette socket of a car,
use cigarette lighter cable (EDH-32).
• Turn the transceiver's power off when connecting or
disconnecting the DC cable.
* This adaptor has been designed as a battery charger. A noise may occur in RX/TX
signals. The noise won't harm the transceiver and is not a defect. Use of a
regulated power supply is recommended.

■Attaching and Detaching the Battery Pack
●Attaching
1.Align the projections on the
battery pack with the pits on
the transceiver.
2.Push in the direction of the
arrow until the latch clicks.
●Detaching
1.Push the latch upward.
2.Pull out the battery pack in
the direction of the arrow
shown left.
Caution
• The battery pack is not charged when shipped.
It must be charged before using.
• The battery pack can be charged by mounting it on the
DJ-C7 and connecting AC battery charger to the DC
power supply jack on the transceiver.
• It takes up to 2 hours and 30 minutes (maximum) to fully
charge the battery pack.
• Charging should be conducted within a temperature
range of 0 to 40˚C (32 to 104˚F).
• Do not modify, dismantle, incinerate, or immerse the
battery pack in water, as these practices can be
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.
• Please be sure to remove the battery pack when the
transceiver is not in use.
• The battery pack should be stored in a dry place where the
temperature range is between -20 to 45˚C (-4 to 113˚F).
• Typically, the battery pack can be charged up to 500
times.
However, the battery pack can be considered dead if the
period of use drops significantly despite the pack being
charged for the aforementioned charging time.
When this happens, a new pack should be used.
• In the interests of environmental protection, do not
dispose of the used battery pack improperly. Check with
your local solid waste officials for details on recycling
options or proper disposal in your area.
Caution
When carrying
• Do not carry the DJ-C7 in the pants pocket. It may
damage the transceiver when you sit.
• The DJ-C7 has been tested for anti-shock and/or against
drops for daily use, but does not comply with militaryspecs. Please be careful not to drop it or subject it to
excessive stress/shocks.

■Preventing Short Circuiting the Battery Pack
Be extra cautious when carrying
the battery pack; shortcircuiting will produce surge
current possibly resulting in fire.
■AC Battery Charger (EDC-126/128)
●Recharging
1.Mount the battery pack on
the transceiver.
2.Connect AC adaptor plug to
the external power supply
jack on the transceiver.
3.Connect the power plug to
an outlet.
Regardless of whether the power switch of the transceiver is on
or off, it will start charging.
Low battery Indicator shown below blinks and the TX/RX lamp
illuminates red during charge when the transceiver is off. Once it
is fully charged, the TX/RX lamp will turn green.
Caution
• Be sure to connect the charger to the battery pack after
mounting it to the transceiver. Otherwise, the battery
pack won't be recharged.
• Disconnect the charger from the outlet while not using it.
• Never charge the battery packs of other manufacturers
with this charger.
• The required charging time depends on the condition of
the battery pack.
• Never short-circuit the terminals of the battery pack with
metal objects and the like. Both this charger and the
transceiver could be damaged.
• The charger does not work when the voltage from an
outlet is extremely low.
■Low Battery Indicator
• Battery consumption level may change depending on the
surrounding temperature or the frequency of use.
• Charge the battery when the Low Battery Indicator appears.
• The Low Battery Indicator is not an indicator for battery life remaining.
Low Battery Indicator
The charge level is low.
