CALL DENIED (TRUNKED MODE ONLY)

If the radio is keyed and a low pitched tone is heard then the radio is not authorized on the system that has been selected.

CARRIER CONTROL TIMER

If the programmed time for continuous transmission is exceeded, five short high-pitched warning tones followed by a long low-pitched tone will be heard. The transmitter will shut down shortly after hearing the alert, interrupting communications. Release and re-key the PTT button to maintain communications. This will reset the carrier control timer and turn the transmitter back on.

KEY PRESS ALERT

A short tone or "beep" sounds to indicate a key has been pressed. A short low-pitched tone indicates no action was taken because the key is not active in the current mode.

DUAL CONTROL SWITCHING

When control is switched to a previously idle control unit, two short high- pitched tones will sound at the control unit where PTT was pressed, that is now the active controller.

OPERATION

The ORION mobile radio unit can be programmed to operate in either a trunked system or a conventional system or both. Operating features and functions have been grouped according to the type of system the radio is operational. This first section contains general operating procedures (e.g., Turning On The Radio). The second section, TRUNKED MODE OPERATION, covers those operating procedures that are only used in a trunked system (e.g., Group Scan). The third section, CONVENTIONAL MODE OPERATION, covers those operating procedures that are only used in a conventional system (e.g., Squelch Adjust). The fourth section, TRUNKED OR CONVENTIONAL MODE OPERATION, covers those operating procedures that may be used in either a trunked or conventional system (e.g., Multiple Radio Operation).
