Basic Radio Operation
Radio On/Off; Power-Up
1.
Turn the radio on by rotating the volume control
clockwise. The radio goes through a power-up self
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
“ E R R O R X X / X X ” ( w h e r e X X / X X i s a n
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

periodically checked by an authorized Motorola
service shop.

transmissions from a radio that has the same
key as the monitoring radio will be heard clearly,
unless the monitoring radio has had its key
erased or is using a different key; then, the
transmission will be heard as noise that is nearly
indistinguishable from channel noise.
