Basic Radio Operation
Radio On/Off, Power-Up
Turn the radio on by rotating the on/off/volume
control 1/4-turn clockwise. The LED on top of the radio
will light green, and a SELF TEST screen will appear on
the LCD to indicate that the radio is performing a self
test. A high-pitched tone (Radio Ser vice Software
programmable) is generated to indicate that the radio
has passed the self test. If a low-pitched tone, screen
display FAIL 01/82, or any combination of the two
occurs (indicating a malfunction), turn the radio off,
check the battery, and turn the radio back on.
Do not remove the battery from the radio
during power-up or during any programming
sequence. This could corrupt codeplug data.

operational status of the microprocessor-based
systems but does not check all of the radio
frequency components and does not 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.
Selective Channel Display and HOME Key
After power-up, a selective channel display is
shown. This display is a per radio feature programmed
by Radio Service Software one of two ways:
•
one way, the dispatch display, shows the channel
number (selected by the channel selector) and a
number that represents the squelch code assigned
to that receive channel. If the PTT is pressed while
viewing the dispatch display, the display will not
change.
•
the other way, the numeric display, shows the
receive frequency of the channel (selected by the
channel selector) and the squelch type or squelch
code assigned to that receive frequency. If the PTT
is pressed while viewing the numeric display, the
display will change to show the transmit frequency
and the transmit squelch type or squelch code.
When in the programming mode, if no keys are
pressed in 15 seconds (Radio Ser vice Software
programmable), the radio will automatically exit that
mode and return to the selective channel display.
The HOME key is used to exit the current menu
screen and return to the previous menu screen. If the
existing menu allowed data entry and side button 1 was
not pressed, pressing the HOME key will cause that data
to be lost.
