To access the Key Pick List, press the microphone’s
[FCN]
button. The
display momentarily shows ‘KEY ##’, where ## is the number of the
currently selected transmit key, and then shows the key’s label. If no
key has been selected (default keys are being used), the display shows
‘KEY DFLT.’ If the
[FCN]
button is pressed again, the radio displays the
first of any soft switches assigned to the function menu (see page 12).
Press the microphone’s
[PRI]
button to step through the list of key
labels, or enter the number of the desired transmit key. Press the
[ENT]
button to activate the selected transmit key. Press “0” or the
[CLR
]
button to return to using default (pre-programmed) transmit keys on all
channels.
If a key is selected that has not been programmed, when PTT is pressed,
the radio will not transmit but will beep and display ‘NO KEY’.
ZEROIZATION
The radio provides a method for the user to panic-zeroize all encryption
keys. This service also sets all touchpad passwords to ‘FFFFFF’. The
zeroization service is invoked as follows:
Press and hold the microphone’s
•
[CLR]
button.
Wait for the radio to start beeping and for the ‘ZERO ALL’ message
•
to appear on the display.
While continuing to hold the
•
[CLR]
button, press and release the
PTT switch.
Release the
•
[CLR]
button.
The radio will stop beeping and the ‘ZEROIZED’ message will appear
•
on the display after all keys are destroyed.
If the
[CLR]
button is released before PTT is pressed, keys and
passwords will not be destroyed, and ‘CANCELED’ will appear on the
display.
CHANNEL GROUPS
Radios are separated into groups of 16 channels each. Each group of
16 channels can be programmed to have an “individual personality” with
its own set of operational features.
Select a channel group (if applicable) by pressing the
1.
[GRP]
button and turning the Channel Selector knob. Press the
[GRP]
button again to return to channel select mode. See “GRP” on
page 13.
