Declaring An Emergency Call
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
transmission. *TXEMER* flashes on line two in the displa y until the
emergency is cleared.
3. Press PTT and speak into the microphone in a normal voice.
4. Release PTT when the transmission is complete and listen for a reply.
5. The emergency can be cleared by pressing and holding the c button
followed by pressing the E button then releasing both buttons.
SYSTEM SCAN OPERATION
The radio can be programmed with the following System Scan features.
These features are automatically enabled upon radio power up. A key or
menu option is also defined to allow the System Scan features to be toggled
during radio operation. This is covered in the Menu Selection and Pre-
Programmed Keypad Key sections. The System Scan state will be
maintained through system changes but will default to ON at power up.
Wide Area System Scan
The ORION radio may be programmed for wide area system scan
operation for multi-site applications. Upon the loss of the currently selected
system's control channel, radios may be programmed to automatically scan
the control channels of other systems. If a new control channel is found, the
radio will switch to the new system and sound an alert tone.
