Emergency Operation

If the pre-programmed groupset on the currently selected system contains

an EMERGENCY/HOME group and the radio is in dynamic regroup, the radio

will exit dynamic regroup and declare the emergency on the HOME group. If

no EMERGENCY/HOME group is present, the radio will declare the

emergency on the currently selected dynamic regroup group.

AEGIS OPERATION

VOICE MODES

Each system (trunked or conventional) in the radio can be programmed

for Aegis communications. Aegis programmed systems have two (2) different

voice modes: clear (analog) and digital. The voice modes are programmed on

a per-group basis within each trunked system and on a per-channel basis within

each conventional system. A radio must be equipped with the encrypt/decrypt

option before it will operate in Aegis mode.

Each channel or talk group (EDACS) can be programmed for ANALOG

Voice, Aegis Digital Voice, or Aegis VGE Encrypted Digital Voice mode

of operation by programming the "KEY" variable

When programmed "DIS", a channel or talk group will only operate in

the ANALOG mode. ANALOG voice calls can be easily monitored by

unauthorized persons.

When programmed "DIG", a channel or talk group will only transmit

Aegis Digital Voice. Aegis Digital Voice and ANALOG Voice calls can

be received.

When programmed "1-6", a channel or talk group will transmit Aegis

VGE Encrypted Digital Voice. Valid cryptographic keys must be loaded

into the MDX using the Universal Key Loader. The "PVT" icon

(indicating encrypted mode is on) can be turned on and off using one of

the AUX keys or by chosing "FORCED" as the mode of operation in the

programmer.
