RECEIVE ONLY CHANNEL
If the selected channel is programmed as receive
only the radio will sound an alert tone if a transmission
is attempted. "RX ONLY" is displayed.
RADIO/CHANNEL FAILURE
If the synthesizer is unable to lock correctly on the
selected channel, or another radio failure occurs, an
alert tone will sound. If incorrect programming is
detected or the synthesizer fails to lock, the display
flashes "NO LOCK" then the selected channel’s
name.
OPERATION
POWER-UP
After the battery pack and antenna have been
installed, turn the radio on by sliding the ON/OFF
SWITCH on the battery pack up. After the radio has
completed a power-up self-test, it will begin operation
on the last operating state as displayed in the LCD. If
programmed on, the power-up alert tone (beep) will
be heard.
CRYPTOGRAPHIC KEY HANDLING
Cryptographic keys are transferred into the radio
using the Keyloader, Option V4025. Refer to the
Keyloader operator’s manual (LBI-31541) for detailed
instructions on how to load keys into the Keyloader.
The radio is capable of storing up to seven (7)
different cryptographic keys in its memory. It is pro-
grammed for key selection on a per channel basis.
Transferring Keys Into The Radio
The following procedure outlines basic key trans-
ferring steps. See LBI-31541 for more details.
1.
Turn the radio off.
2.
Plug the modular connector of the Key-
loader cable into the Keyloader’s modular
jack.
Before private messages can be sent or
received, one or more cryptographic keys
must be transferred into the radio from the
Keyloader.
