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 p ressed. 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 b oth. 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).
