power indicator will turn on.
3. The equipment can start operation.
Note:
At power off state, there is still certain power consumption with the main unit. If the
main unit can not be turned on when pressing down the switch, that is to say the
battery is running up and needs charging.
Note:
When the main unit charging/volume indicator light is flashing, that is the battery is
running up and it should be charged as soon as possible.

- 13 -
Warning:
It is prohibited to use any other power supply except the standard adapter as the
external power supply for the main unit.
2.5 Battery charging
There are 3 ways to charge the battery.
2.5.1 Charging through main unit
1. Install the battery correctly into the main unit.
2. Insert the plug of “ ” of the adapter into the “DC14V/3A” interface on the rear.
3. Connect power cord of “ ”of the adapter to the AC. EPS.
4. Whenever the main unit is power on or off, the “Charging/Volume” indicator light turns on, it means
the battery is charged through adapter; when the lights turn on, it means the battery is fully
charged(refer to figure).
Charging through main unit
Tip:
To prolong the battery operation time, please finish charging when the indicator lights
show that the battery is full.
2.5.2 Charging through adaptive line
1. Take out the battery from the main unit or take out the spare battery.
2. Connect the round end of the adaptive line to the " " terminal of the adapter, and the flat end to
the charging terminal of the battery.
3. Connect power cord of " " of the adapter to theAC EPS.

- 14 -
4. When the " " indicator light on the adapter turns into red, the battery is in charging; when the
" " indicator light turns into green, the battery is fully charged. (Refer to figure).
Charging through adaptive line
2.5.3 Charging through auto-charger
1. Take out the battery from the main unit or take out the spare battery.
2. Connect the flat end marked with an arrow of the auto-charger to the charging terminal of the battery.
3. Plug the other end of the auto-charger into the cigar lighter socket.
4. When the "Charging" indicator light on the adapter turns into red, the battery is in charging; when the
"Charging" indicator light turns into green, the battery is fully charged. (Refer to figure).
Charging through auto-charger
Tips:
The input voltage of the auto-charger is DC9～14V/1.5A.
The output voltage of the auto-charger is DC12.6V/1A.
The operations and storage environment are the same as those of the main unit.
