Possible Causes
Radio module is malfunctioning.
Radio modules are out of
synchronization.
Radio module is malfunctioning.
Radio module was inserted
without first powering down the
carrier. Carrier is out of
synchronization.
Electrical outlets may not be up to
specifications. Electrical problems,
such as no ground or floating
ground, can cause the switch to
send or receive spurious current,
causing problems in switch
protocol.

Possible Solutions
Replace the radio module.
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 Customer
Support.*
1 Remove all but one radio module from
the carrier. (See "Removing Radio
Module from 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.
If the PASS LED does not light, the
3
radio module is malfunctioning. Replace
the radio module and handset.
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 Customer
Support.*
Verify that the outlets for the
communications system switch and for the
carrier(s) meet electrical requirements. (See
"AC Outlet Check" in Chapter 2.)
