radio will transmit private if the group/channel is programmed for private
operation and forced operation is pre-programmed.
If the radio was pre-programmed for auto select, the radio will transmit in the
following modes;
•
Private mode enabled, transmission always in private mode.
•
Private mode disabled and private call received. Reply transmission will
be private mode if made during scan hang time. If reply transmission
occurs after scan hang time, transmission will be in clear mode.
Aegis or ProVoice transmissions cannot be received by a radio set to receive a
Voice Guard transmission. Accordingly, Voice Guard or ProVoice
transmissions cannot be received by a radio set to receive an Aegis
transmission. Neither of the Aegis or Voice Guard transmissions can be
received by a radio set to receive ProVoice.
Cryptographic keys are transferred to the radio using a cryptographic
Keyloader. Up to seven (7) different cryptographic keys, numbered 1-7, can
be transferred from a Keyloader and stored in the radio. An individual key is
automatically selected on a per-group/channel basis according to the radio's
programming. Groups and channels within Aegis, ProVoice, or Voice Guard
systems can be programmed for keys 1-7. Up to 8 banks of 7 keys can be
stored for Aegis (DES and VGE) systems.
DES radios require a DES Keyloader (Option V4025 with software version
3.n or later). VGE radios require a VGE Keyloader (Option V4028 with
software version 2.n or later).
When operating on a group or channel programmed for private mode, all
transmissions will be private transmissions and the radio will receive clear and
private signals. The PVT key light (System Model) or OPTION key light
(Scan Model) turns ON when the private mode is enabled. If the selected
group or channel is programmed for auto select capability, the mode may be
toggled between private and clear with the PVT button (System Model) or
O
button (Scan Model). Radios programmed for forced private operation do not
allow a change of the transmit mode; therefore, the PVT button (System
Model) or
O
button (Scan Model) has no effect.
Transferring Keys Into The Radio
The following procedure outlines basic key transferring steps.
1. Turn the radio OFF.
2. Ensure that the PC programming cables and adapter box are disconnected
from radio unit.
3. Plug the modular connector of the Keyloader cable into the Keyloader
modular jack.
