Installation and Connection 2-11
2-11-2. Charging the battery
1. Connect the battery to the projector.
2. Make sure the projector is turned off.
3. Connect the adaptor's power cable to the [ ] port on the back of the projector.
4. Plug the adaptor's power cord into an electrical socket. The battery starts charging automatically.
• The battery is not used while the projector is connected to a wall outlet through the adaptor.
(If you connect the power supply, you can use the projector when the battery is not connected.)
We recommend that you keep the battery connected to the projector even when the projector is connected to a wall
outlet.
• The battery needs to be charged for about three hours if fully discharged. Do not turn on the projector when charging the
battery.
• The video playback time may differ depending on the LED mode as follows (with the battery fully charged):
(The playback time may be shortened for a video played from external memory.)
<Settings> - <LED Mode> - <Normal>: Play videos for about one hour from internal memory.
<Settings> - <LED Mode> - <Eco>: Play videos for about two hours from internal memory.
• The screen brightness may differ when the projector is operated only with the battery, depending on the remaining
power.
• The battery charge time and discharge time (time until another charge is needed) depend on the number of previous
charges and the charge and usage conditions. The battery consumes power even when the device is not in use. Over
time, the maximum operating time gradually shortens. (If the maximum operating time decreases by more than half, it is
time to buy a new battery.)
• The red LED ( ) indicates the battery is being charged. / The blue LED (
)
indicates the battery is fully charged.
