Move the handset at least 6 feet
(1.8 m) away for a one- or two-
carrier setup, or 10 feet (3.1 m)
away for a three-carrier setup.
Fully extend the handset antenna.
Reinstall the radio module or carrier
away from electrical equipment and
as high as possible on the wall [but
with radio module antennas 6 to 12
inches (15.2 to 30.5 cm) from the
ceiling]. (See "General Positioning
Rules" in Chapter 2 for more
information.)

Troubleshooting
Remove all but one radio
module from the carrier. (See
"Removing Radio Module from
Carrier" in Chapter 4.)
Test each radio module
individually, verifying that the
POWER and PASS LEDs on
each radio module lights when
the carrier is powered, and that
the OUT OF SYNC LED is not
lit.
If the PASS LED does not light,
the radio module is
malfunctioning. Replace the
radio module and handset.
