Possible Solutions
Reinstall the radio module
or carrier assembly as
high as possible on the
wall and away from metal
obstructions.
Eliminate any possible
interfering devices (micro-
waves) between the radio
module or carrier assembly
and your handset.
Turn off or unplug nearby
equipment (computer,
modem) to see if it is
causing interference. If it
is, make sure it is on a dif-
ferent power line or move
it further away from the
handset, radio module, or
carrier assembly.
Place the handset in
Wireless Test Mode as
described on page 10. If the
signal strength and voice
quality readings are low,
look for a newly installed
radio device nearby.
Remove it or move your
handset's matching radio
module.
Place the handset in
Wireless Test Mode and
determine sound clarity as
described on page 10. If
the dial tone is clear and
strong, the handset and
radio module are OK.
Check the connection
between the radio module
or carrier assembly and
the switch/control unit.
Report line trouble to your
local phone company.
