The Aurora radio display can be backlit,  and your dealer
programmed one of the following options for your radio:

1. Backlight on whenever you press a key (1–6-second auto

timeout)

2. Backlight on whenever a signal is received and the audio is

sent to the speaker (1–6-second auto timeout starting at
carrier drop)

3. Backlight on whenever you press a key or a signal is

received and the audio is sent to the speaker (0–6-second
auto timeout starting at key press or carrier drop)

4. No backlight  (military/strategic applications). This option also

prevents the Transmit/Busy/Low Battery LED to light up.

Note:  If Option 4 of the display backlight LED feature is
programmed, the multicolored status LED will not light
under any condition.

The Aurora radio advanced models have a keypad that contains the
keys necessary to access a channel group directly, generate DTMF
tones and paging codes, and change operating modes. The keypad
is backlit and controlled by the same backlight control as the
display.

audio received from active carriers on tuned receive-channel
frequencies. The internal speaker also lets you hear any audible
notifications.

The Aurora radio has an internal microphone so you can transmit
