CONVENTIONAL FAILSOFT

In the unlikely event of a failure of the EDACS system, communications can

take place in conventional failsoft mode. The radio will be automatically

directed to a communications channel set up for this purpose. During this

mode of operation, the control unit will display CONV FS in the

alphanumeric display. An increase in activity on the channel during

conventional failsoft operation may be noticed, so be careful not to transmit

until the channel is clear.

Operation during conventional failsoft will be the same as operation on a

conventional system, except that it will not be possible to select a

communications channel, or use emergency and special call. When trunking

is restored, the radio will automatically be returned to normal operation.

NOTE

Emergency and Special Call are not operational during

conventional failsoft. In addition, the GROUP control will not

operate.

EMERGENCY OPERATION

The radio's ability to declare an emergency, clear an emergency, remain

locked on an emergency and group, and the emergency audio and display

freeze can each be enabled or disabled through programming. When an

emergency is declared scanning will stop and will restart only after the

emergency has been cleared.

Receiving an Emergency Call

When receiving an emergency call from the selected group and system, an

alert beep is heard and the BSY indicator lights. The message *RXEMER*

flashes in the display on line 2 until the emergency condition is cleared.

Follow standard emergency procedures.

Declaring an Emergency

To send an emergency call to the selected system and group (or on an

optionally pre-programmed emergency group), proceed as follows:

1. Press and hold the red

E button for approximately one second. (This

time is programmable and therefore could be longer or shorter. Check with

the system administrator.) The radio will transmit an emergency call

request with the radio ID until an emergency channel assignment is

received.

2. When the working channel assignment is received, the radio sounds a

single beep (Autokey alert tone) indicating it is ready for voice
