14 Basic Radio Operation
1. Turn the radio on by rotating the volume control clockwise. The radio goes
through a power-up self check and, if it passes the check. A high-pitched tone
sounds to indicate that the radio has passed the self check. (tone optional via
RSS).
If the radio fails the self check, you will hear a low-pitched tone. Turn the
radio off, check the battery, and turn the radio back on. If the radio still does
not pass the self check, a problem exists in the radio. Contact your nearest
Motorola Service Shop.
Note: The power-up self check verifies that the radio's microprocessor-based
systems are working, but it does not check all of the RF components, nor
does it check the operation of all customer-specific features. Motorola
recommends that the functionality of the radio be periodically checked by an
authorized Motorola service shop.
2. Turn the radio off by rotating the volume control counterclockwise until you
hear a click.
Before you can send or receive on a trunked
system, the radio must be set to the desired
system and mode. In trunked operation, a mode
is a trunked talkgroup and all features "slaved" to
it . Your radio can support up to four different
trunked systems, selected by mode selector knob
positions 1 through 16. Each system can have
up to four different modes associated with it.
When you move to a position, such as mode 1,
you are selecting both a system and talkgroup.
For example, mode 1 could select system
1/talkgroup 1; mode 2 could select system
1/talkgroup 2.To select a system and mode:
1. Turn the radio on and set the mode selector
k n o b t o t h e d e s i r e d m o d e p o s i t i o n ( 1
through 16).
