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.
