RADIO OPERATION

Turning The Radio On or Off

To turn the radio on, turn the On-Off/Volume

Control knob clockwise.

To turn the radio off, turn the On-Off/Volume

Control knob counterclockwise until you hear a

click.

Adjusting the Radio's Volume

Turn the On-Off/Volume Control knob to adjust

the volume level.

Listen until you hear a transmission, then adjust

the volume control for a comfortable listening level.

Or, if a button is programmed for "volume set,"

press this button and adjust the volume to a com-

fortable listening level.

Radio Self Test

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, the display

momentarily shows "SELF TEST." A good-power-up,

high-pitched tone sounds to indicate that the radio has

passed the self check.

If the radio fails the self check, the display shows

OFF

"ERROR XX/XX" (where XX/XX is an alphanumeric

error code), accompanied by a bad-power-up, 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.
