(Continued) You have a malfunctioning radio
module.
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, and that the
OUT OF SYNC LED is not lit.
3 If the PASS LED does not light,
the radio module is
malfunctioning. Replace the
radio module and handset.
Handset voice quality
and range are not as
good as they were
earlier.
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.
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.
Range for calls is lower
than expected.
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.
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 the top of the 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.)
See “TransTalk 9000 System” in
Chapter 1.
