Precautions
Precautionary Statement
• Do not open the case nor touch the interior components.
Tampering can damage the receiver.
• Do not place the receiver in any place where it will be
subjected to direct sunlight, dust, or high temperatures.
• Keep the receiver away from TVs, tuners, or other equipment
if it interferes with reception.
• Ensure that the provided antenna is securely mounted.
• Turn the power OFF immediately if the receiver should emit
smoke or strange odors. Ensure that the receiver is safe, then
contact the nearest Alinco Service Center.
Precautionary Statement - External Power Supply
• Use a regulated 3.7V to 6.0V DC external power supply.
• Never use any external power supply which exceeds 6.5V.
Otherwise, this may cause the serious damage.
• To charge the battery or operate the receiver using AC power,
use the provided AC adapter (EDC-126 or EDC-128
depending on the version). Connect the adapter to the
receiver's DC-IN jack directly.
• When power is supplied from the cigarette socket of a car,
use the optionally available cigar-socket DC cable (EDH-32).
• Turn the receiver's power OFF when connecting or
disconnecting the cable of external power supply.
Request and Agreement
• This receiver is manufactured and shipped under strict quality
control. However, in some rare instances, if questionable or
doubtful points are found, please notify the store where you
purchased the receiver.
• Since this is a wide band communication receiver, its internal
oscillation can sometimes block a signal, or detect an internal
signal (sometimes referred to as a "birdie"). These symptoms are
not a malfunction.
• Specifications and information found in this document are
subject to change without notice.
• DJ-X7 is a wide band receiver and can be applied to
business use.
• DJ-X7 receives AM radio with the internal bar-antenna.
• DJ-X7 receives high frequency wave (shortwave) with the
internal bar-antenna.
• DJ-X7 receives FM radio with the provided earphone antenna.
• DJ-X7 features the Shift function.
• DJ-X7 features the Tone Squelch function, and it covers 39
CTCSS tones.
• DJ-X7 features the Cable-clone function.
• DJ-X7 features the PC Connection function*.
• DJ-X7 adopts Lithium ion rechargeable battery.
* The free editing software can be downloaded at our website
(http://www.alinco.com). The optional PC interface-cable
(ERW-4C) is required to interface your computer and the
DJ-X7. Please visit our website for more details before you
purchase the ERW-4C as some restrictions may apply
depending on your computer conditions.
1.1 Standard Accessory List

2.1 Mounting Arrangement
■Installing & uninstalling antenna
●Installing antenna
1.Hold the antenna at the base.
2.Attach the antenna to the
antenna connector.
3.Turn the antenna clockwise
until it stops.
4.Ensure the antenna is securely
installed to the receiver.
●Uninstalling antenna
Turn the antenna counterclockwise.
Caution
When antenna connector conversion is necessary, be sure
to select a proper conversion connector or cable which
does not overburden the receiver. Otherwise, this may
cause the damage to the receiver and/or the antenna.
Installing an excessively high performance external
antenna may get worse of the receiving conditions.
■Installing & uninstalling battery
●Installing battery
1.Align the projections on the
battery with the grooves on
the receiver.
2.Push the battery in the direction
of the arrow.
3.Push down the latch of the
battery until it clicks.
●Uninstalling battery

Caution
• Do not modify, dismantle, incinerate, or immerse the
battery pack, as these practices can be dangerous.
• Do not short-circuit the terminals of the battery pack. This
may cause damage to the receiver. The short-circuit may
lead to overheating the battery, which causes burns.
• The battery pack should be stored in dry places where
the temperature range is between -20 to 45˚C (-4 to
113˚F). Leaving the battery pack exposed in high
humidity or outside the proper temperature range may
cause battery liquid leakage or rust on the metal portion.
• The battery pack is not charged when shipped. It
must be charged before use.
• The battery pack can be charged by plugging the AC
adapter to the DC-IN jack of the receiver after
mounting it to the DJ-X7.
• It takes up to 2 hours and 30 minutes (maximum) to
fully charge.
• Charging should be conducted within a temperature
range of 0 to 40˚C (32 to 104˚F). Otherwise, the
battery won't be charged properly.
• Be sure to remove the battery pack when the receiver
is not in use for a long period.
• Typically, the battery pack can be charged up to 500
times. However, it is considered consumed if the period
of use significantly drops despite the battery being
charged for the aforementioned charging time. When
this happens, replace the old battery with a new one.
• In the interests of environmental protection, do not
dispose of the battery pack improperly. Check with
your local solid waste officials for details on recycling
options or proper disposal in your area.
• It is not necessary to turn the power OFF of the
receiver while charging. However, noise may occur
during reception.
■Precaution for preventing short-circuit of battery
Be extra cautious when
carrying the battery pack; the
short-circuit will produce surge
current possibly resulting in
fire.
Put it in a non-conductive plastic bag, or wrap it
with a non-conductive material when you carry.
Protect it by
spreading a nonconductive sheet.
DON'T carry with any
type of metals. (e.g.
chains)
DON'T put it in bags
whose interior is
plated with metal.
DON'T wrap with a
metal plated cloth.
DON'T place it in the
proximity of metals or
conductors. (e.g.
nails, chains)

■Receiving while charging with AC adapter
●Charging battery
1.Install the battery pack to the
receiver.
2.Plug the AC adapter to the
DC-IN jack of the receiver.
3.Plug the power plug to an
outlet.
(EDC-128 has different shape.)
Regardless of whether the power ON or OFF of the receiver, it
will start charging.
When the receiver is OFF state, the low battery indicator shown
below blinks and the RX lamp illuminates during charge. Once
it is fully charged, the lamp will go off.
Caution
• Never charge batteries of other manufacturers. Never
plug the provided AC adapter to other devices, either.
• If you should short-circuit the terminals with metal objects
and the like, it may cause damage to both the receiver
and the battery.
• Be sure to connect the AC adapter after mounting the
battery pack to the receiver. Otherwise, the battery
won't be charged.
• Be sure to unplug the AC adapter when it is not in
use.
• The required charging time depends on the condition
of the battery pack.
• The battery won't be charged if the voltage from an
outlet is extremely low.
■Low battery indicator
• Battery consumption level may change depending on the
surrounding temperature or the conditions of use.
• Charge the battery when the indicator appears.
• This is not an indicator for battery life remaining.
Low battery indicator
Indicates the charge level is
low.
