- Precautions on Safety for Replacement of Backlight
US,EW
· High voltage is generated in the inverter when the power is supplied to the system. To avoid an electric shock, reconfirm that the power switch is set to OFF before starting operation. · The fluorescent tube and high-voltage parts have high temperature immediately after the power switch of the main unit is set to OFF. To avoid burning your hand or similar accidents, wait awhile after turning the power to OFF, then start operation. · High voltage may be charged to the inverter immediately after the power switch of the main unit is set to OFF. Wait awhile after turning the power to OFF, then start operation. · In some cases, the fluorescent tube of backlight may be damaged. Take adequate caution for injury during operation.

1 BACK LIGHT switch
The brightness of the light built into the display to illuminate the LCD screen (the back light) can be set to either of two levels: Bright or Dark.
Dark Bright
3 VOLUME control
Controls the volume of the display speaker.
Softer Louder
· The back light is dimmed automatically when the vehicle's lights are turned ON to make the screen easy to see at night.
· Make sure the volume level of your system is set to a level that will permit you to hear outside traffic or emergency vehicles.
4 Speaker 5 Signal receiver
This receiver receives signals from the remote controller supplied with the audio visual master unit.
2 BRIGHT control
Controls the brightness of the image colors on the LCD screen.
Dark Bright
6 POWER indicator light
This light comes on when the system power is ON. · The color of the LCD screen may appear lighter or darker depending on the angle of vision. In this case, the brightness of the image can be adjusted with the BRIGHT control.
