Using the Digital PTT ID Feature
This feature allows you to the radio ID (number) of the radio
from whom you are currently receiving a transmission. This ID,
consisting up to a maximum of eight characters, can be viewed
by both the receiving radio and the dispatcher.
Your radio's ID number is also automatically sent every time the
PTT button is pressed. This is a per-channel feature. For digital
voice transmissions, your radio's ID is sent continuously during
the voice message.
Controlling the Display Backlight

You can enable or disable the radio's display backlight as needed, if
poor light conditions make the display difficult to read.
Depending on how your radio is preprogrammed, you can also maintain
a minimum backlight level on the radio's display.
Procedure:
Note: Press the DIM button to toggle the backlight on or off.
OR
Press any key of the keypad, the Menu Select or Menu
Navigation buttons, or any programmable radio controls or
buttons to turn the backlight on.

Using the Time-Out Timer
This feature turns off your radio's transmitter. You cannot
transmit longer than the preset timer setting.
If you attempt to do so, the radio automatically stops your
transmission, and you hear a talk-prohibit tone.
The timer is defaulted at 60 seconds, but it can be
preprogrammed from 3 to 120 seconds, in 15-second intervals,
or it can be disabled entirely for each radio mode, by a qualified
radio technician.
Note: You will hear a brief, low-pitched, warning tone four
seconds before the transmission times out.
Procedure:
1
Hold down the PTT button longer than the preprogrammed
time. You hear a short, low-pitched warning tone, the
transmission is cut-off, and the LEDs goes out until you
release the PTT button.
2
Release the PTT button. The LEDs relight and the timer
resets.
3
Press the PTT button to re-transmit. The time-out timer
restarts and the red LED lights up.
