Philips PPX4350/INT ユーザーズマニュアル

The capacity of the battery diminishes with time. You 
can prolong the life of the battery if you observe the fol-
lowing points:

• Without a power supply, the device operates 

from the built-in battery. When the battery does 
not have sufficient capacity, the device turns off. 
Connect the device with USB cable on an USB 
port.

• When the battery does not have sufficient capac-

ity, the battery symbol in the display becomes 
red.

• When the device is running for a long period of 

time, the surface becomes hot and a warning 
symbol appears on the projection. The device 
behaves as follows:

1 The fan turns to maximum level.
2 At maximum level of brightness the overheat 

symbol appears in the status bar and the device 
turns automatically to minimum level of bright-
ness.

3 At minimal level of brightness the overheat 

symbol shows for three seconds in the middle 
of the screen. Then the device turns off auto-
matically.

After the device has cooled down, you can con-
tinue playback.

• Use the device at least once a week.

• Charge the battery regularly. Don’t store the 

device with a completely discharged battery.

• If the device is not used for several weeks, dis-

charge the battery a little by using the device 
before storing it.

• If the device only works using the USB connec-

tion or with the power supply, the battery is 
defective.

• Keep the device and the battery away from 

sources of heat.

When the battery is in deep discharge or the device is 
not used for a longer period, proceed as followed:

1 Connect the device to the power supply (see also 

Connect Power Supply / Charge Battery, page 8). 
The device behaves as follows:

2 The device can be turned on and is ready to use after 

approximately five minutes of charging time.

Do not try to replace the battery yourself. 
Incorrect handling of the battery or using the 
wrong type of battery can cause damage to 
the device or cause injury.
