Front Panel

This screen provides control of the front panel LCD illumination. The

LCD illumination may need to be enabled to view the LCD depending

on ambient lighting conditions.

This screen allows you to adjust the viewing angle (top to bottom) of the

LCD screen. The angle may need to be adjusted to compensate for the

radio mounting position and ambient lighting conditions. Use the

keys to adjust the screen. Pressing

saves the adjusted value as the

default setting.

This screen allows the radio beeper to be disabled or enabled. The

beeper provides a short “chirp” whenever a front panel key is pressed.

This screen allows you to set the time delay that occurs before a key will

start repeating its function when held down.

This screen allows you to set the default screen that appears when the

radio is first turned on, or is left idle for more than 10 minutes. The RSSI

screen is commonly chosen, but any screen may be selected as a default.
