Voice Quality Problems
Symptom Possible Causes Possible Solutions
Handset voice quality 
and range are not as 
good as they were 
before.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.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.
Carrier(s) are out of synchronization 
(the OUT OF SYNC LED is lit).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.
Antenna of the radio module is too 
close to the ceiling.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.

(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 PA S S LEDs on 
each radio module lights when 
the carrier is powered, and that 
the OUT OF SYNC LED is not 
lit.
3  If the PA S S LED does not light, 
the radio module is 
malfunctioning. Replace the 
radio module and handset.
Voice quality in a 
specific location is poor 
and noisy.Handset is too close to the carrier(s). 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.
Voice quality 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 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.)

You are on a call and 
you hear radio 
interference when 
another call rings.Communications system in key mode 
has all lines set to ring. An incoming 
call “wakes up” all of the other radio 
modules at the same time to ring the 
other phones.Refer to Chapter 6, “MDW 
9031/9031DCP Pocket Phone 
Compatibility,” to reset line ringing 
options.
Voice quality for a call 
in progress degrades for 
more than 6 seconds 
(PARTNER, PARTNER 
Plus, PARTNER II, 
PARTNER Advanced 
Communications 
System in key mode, 
MERLIN, MERLIN 
Plus, and MERLIN II 
Systems only).Line ringing options are incorrectly 
set for extensions with radio modules 
in the first expansion carrier.Refer to Chapter 6, “MDW
