Possible Causes
Possible solutions
Handset voice quality
and range are not as
good as they were
earlier.
A competing radio device (for
example, a wireless bar-code scanner)
has been installed in the area. Both
products are competing for the same
air space and will conflict when both
are being used.
Carriers (s) are out of synchronization
(the OUT OF SYNC LED is lit).
Antenna of the radio module is too
close to the ceiling.
Place the handset in Wireless Test
Mode as described in Chapter 3. 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 at least 6 feet
(1.8 m) away from the potential
interference.
For a single-carrier installation:
1
Power down.
2
Wait 15 seconds, then repower
the carrier.
For a multiple-carrier installation:
1
Verify that all expansion cables
are fully inserted in the correct
IN and OUT jacks.
2
Check CONTROL/
EXPANSION LEDs for correct
color. (See “Understanding Your
Model 117A4 Carrier” in
Chapter 2.)
3
Ensure that each carrier has at
least one radio module installed.
If the control carrier is a Model
117A3, ensure that there is a
radio module in Slot 6.
4
Power down all carriers, wait 15
seconds, repower the control
carrier, then repower the
expansion carriers in order, from
left to right.
Reinstall the radio module or
carrier(s) so that the top of the radio
module antenna is 6 to 12 inches
(15.2 to 30.5 cm) from the ceiling.
