Troubleshooting
Possible Causes
You have a malfunc-
tioning radio module.
Electromagnetic fields
are interfering.
There is a large metal
object within 3 feet
(1.2 m) of the radio
module.
There is a large metal
object in the "line of
sight" to the radio
module.
The handset antenna is
only partially extended.
There are environmental
limitations.
You are using different
models of handsets and
the mix is incompatible
with the carrier.
Possible Solutions
Remove all but one radio module
1.
from the carrier. (See "Removing
a Radio Module from the Carrier"
in Chapter 4.)
Test each radio module individu-
2.
ally, verifying that the POWER
and PASS LEDs on each radio
module light when the carrier is
powered, and that the OUT OF
SYNC LED is not lit.
If the PASS LED does not light,
3.
the radio module is malfunction-
ing. Replace the radio module
and handset.
Look for 110/Volt lines, fuse boxes,
circuit breakers, electrical junction
boxes, or similar items. Move the
carrier or radio module at least 6
feet (1.8 m) away from the
potential interference.
Move the carrier or radio module at
least 3 feet (1.2 m) away from the
potential interference.
Move the metal object, or move the
carrier or radio module.
Fully extend the handset antenna.
Reinstall the radio module or
carrier away from electrical
equipment and as high as pos-
sible on the wall (but with radio
module antennas 6-12 inches
(15.2–30.5 cm) from the ceiling).
