Possible Solutions
Power down the carrier, wait 15
seconds, and repower it. If you
have multiple carriers, repower
the control carrier first, and then
power the expansion carriers in
order from left to right; or use a
surge-protector strip to repower
all of the carriers at one time.)
If the problem persists, call for
help.*
1. Remove all but one radio
module from the carrier. (See
"Removing a Radio Module
from the Carrier" in Chapter 4.)
2. Test each radio module
individually, verifying that the
POWER and PASS LEDs on
each radio module light when
the carrier is powered.
3. If the PASS LED does not light,
the radio module is malfunc-
tioning. Replace the radio
module and handset.
Power down the carrier, wait 15

all of the carriers at one time.)
If the problem persists, call for
