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.

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.

NOTE • 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

■Receiving while charging with AC adapter

●Charging battery

AC adapter plug

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.

Power plug

(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.

NOTE • 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

Low battery indicator

Indicates the charge level is low.

•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.
