Transferring Keys Into The Radio
The following procedure outlines basic key
transferring steps.
1. Turn the radio off.
2. Plug the modular connector of the Key-
loader cable into the Keyloader’s modu-
lar jack.
3. Connect the Keyloader cable to the UDC
on the radio.
4. Press the PWR button on the Keyloader
and wait for the Keyloader to display
"MASTER MODE".
5. Press the TRN button on the Keyloader.
If necessary, select a different crypto-
graphic key to be transferred into the
radio.
6.
Turn the radio on. The display should
read "KEY LOAD".
7.
Press the EXE button on the Keyloader
to transfer the key. The Keyloader will
display "GOOD 1.x TRANSFER" where
"x" is the selected cryptographic key
number.
8.
Disconnect the cable from the radio’s
UDC. A single beep will be heard from
the radio’s speaker if the power-up alert
tone is enabled. The radio will change
to the selected group or channel as indi-
cated in the display.
Key Zero
All cryptographic keys can be zeroed or
"dumped" when the radio is on by simultaneously
pressing the
S
and
@
buttons for at least
one second. When the key(s) have been zeroed,
the radio will display KEY ZERO and it will emit a
series of beeps. If the cryptographic key(s) are
zeroed, one or more keys must be transferred into
the radio from the Keyloader before private com-
munications may continue.
Before private messages can be sent or
received, one or more cryptographic keys
must be transferred into the radio from the
Keyloader.
