Radio Self Test - Motorola PRO7550 User Manual

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
"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 opera-
tion of all customer-specific features.
Motorola recommends that the functional-
ity of the radio be periodically checked by
an authorized Motorola service shop.
