When operating on a channel programmed for digital mode, all
transmissions will be digital transmissions and the radio will receive clear and
digital signals. The PVT light turns on when the private mode is enabled. If
the selected channel is programmed for autoselect capability, the mode may
be toggled between digital and clear with the flex keys (A1, A2). Radios
programmed for forced operation do not allow a change of the transmit mode;
therefore, the flex keys would have no effect.
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 Keyloader cable into the Keyloader
modular jack.
3. Connect the Keyloader cable to the microphone connector on the
radio unit.
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
cryptographic key to be transferred into the radio.
6. Turn the radio on. Use the M button to access the menu options, then
press the M button repeatedly to select "KEYLOAD".
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 microphone connector. Press the
C
button to exit the keyload operation. The radio will change to the
selected channel as indicated in the display.
DISPLAYING THE CURRENTLY USED CRYPTOGRAPHIC KEY
NUMBER
