Surge-protector (recommended) or a power outlet
Note: Before turning on the power make sure the red voltage selector [Fig. A] under the AC input is set to the
proper voltage. It should be set to 115V for North America and 230V for most European countries. Make sure
you know the proper voltage for your region before turning on the

VOLTAGE SELECTOR
[Fig. A]
Since the AKJ780A contains built-in power amplifiers, speakers, DVD/CDG/CD player, USB player, and SD
card player, the AKJ780A can be used as a self-contained sound system. However, the AKJ780A contains
various audio video outputs to allow the AKJ780A to be connected to multiple TV sets, external sound
systems, and/or multiple sound effect devices. The following content demonstrates the procedures for
connecting the AKJ780A to the AC outlet and other audio video devices.
POWER Switch
1.
When the main POWER switch on the rear panel is at the ON position and the
AC input is connected to an AC outlet, the AKJ780A is powered by the AC
input. When the main POWER switch on the rear panel is at the ON position
and the AC input is not connected to an AC outlet, the AKJ780A is powered
by the built-in rechargeable batteries.
2.
When the main POWER switch is at the OFF position, the AKJ780A can not
be turned on from the POWER button at the front panel.
NOTE: The main POWER switch must be set to the OFF position when the
AKJ780A is not in use.
3.
When the main POWER switch is at the CHARGE position and the AC input is
connected to an AC outlet, the built-in rechargeable batteries will be recharged
until they are fully charged. The CHARGE/VOLTAGE LED light is red when the
built-in rechargeable batteries are being charged. The CHARGE/VOLTAGE LED
light turns green when the built-in rechargeable batteries are fully charged.
NOTE 1: The AKJ780A will be shut off automatically when the built-in rechargeable batteries have been used to a
predetermined low power level. When this happens, have the AKJ780A rechargeable batteries fully recharged
immediately.
NOTE 2: If the AKJ780A is not to be used for a long period of time, have the built-in rechargeable batteries fully
recharged before storing the unit.
NOTE 3: To have built-in rechargeable batteries last longer, use AC power whenever the AC power supply is
available.
CAUTION:
(1)
Recharge the AKJ780A unit after every use.
(2) Ensure that the main POWER switch is set to OFF position before storing the AKJ780A unit.
(3) If the AKJ780A is not to be used for a long period of time, the built-in rechargeable batteries must be recharged
at least every six (6) months.
(4) Do not open or break the rechargeable battery case.
(5) Do not directly connect the “+” pole and the “-“ pole on the rechargeable battery with any conductive object
(such as metal wire) to prevent battery overheat or explosion.
(6) Do not expose the rechargeable battery to fire or high temperature.
(7) There are two rechargeable batteries in the battery compartment. The capacity of each rechargeable battery is
12 Ahr. In the process of replacing the rechargeable batteries, make sure that the “RED” connector is connected
to the “+” pole of the first battery and the “BLACK” connector is connected to the “-“ pole of the first battery.
The “YELLOW” connector is connected to the “+” pole of the second battery and the “BLUE” connector is
connected to the “-“ pole of the second battery. If any of the rechargeable batteries is not connected correctly
as above, one of the built-in protection fuses in the battery compartment will be burned. There are two fuse
holders, one is attached to the cable of the “RED” connector and the other is attached to the cable of the
“YELLOW” connector. Once any of the fuses is burned, replace it with a fuse having the specifications of
8A / 250V.
