INDICATORS

The 4-digit LIQUID CRYSTAL DISPLAY (LCD) uses the two digits on the left side to indicate the System number and the two digits on the right side to indicate the Group/Channel number. In addition there are 9 status indicators that are described on the following pages.

The LCD backlighting can be programmed to turn on anytime a button or key is pressed. It will remain on for a programmable length of time after the button or key is released. Backlighting is programmed on a per Group/Channel basis or it may be programmed to remain off at all times. Each radio that is programmed with backlighting may also be programmed to remain on or off when the PTT bar is pressed.
