Range Problems
Symptom 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.

(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 light 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.
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.)

Note:The MDW 9031 Pocket Phone is fully compatible with the PARTNER family of 
communication systems. For the remaining communications systems, however, you must 
carefully note the functional differences between your wireless phone and the phone type 
identified in the table above. Differences are summarized on the following pages.
Some systems do not support display features. In these cases, the display is not available; the 
MDW 9031 works as a nondisplay set.

Programming Features for PARTNER, MERLIN, and MERLIN LEGEND Systems
On all PARTNER, MERLIN, and MERLIN LEGEND systems, you can assign a feature to an available button (a 
button that does not have a line or another feature assigned to it):
1  To enter programming mode, turn on the handset, press i, then press / 
followed by 0 0.
2  Press the Select button (  ) to move the Selection rectangle to the row of line 
indicators containing the available button.
3  Press the Column button ( ’) under the button that you want.
4  Program the feature (using the procedure described in the manual for your 
PARTNER, MERLIN, or MERLIN LEGEND Communications Systems).
Note:Some features provide a visual indication in the handset display that the 
feature is turned on. Be aware that if you turn off the handset while using 
one of these features, you may forget that the feature is on. To verify the 
status of such a feature, you can simply press the  button to “wake up” 
the phone and activate the display.
5  To exit programming mode, press / followed by 0 0 or turn off the 
handset.
Note:The above instructions do not apply to System 25, System 75, System 85, 
and DEFINITY Systems, because in those systems, features are assigned 
by the System Administrator.
Communications System Compatibility
This section describes some communications system-dependent programming to help you optimize the 
performance of your MDW 9031 Pocket Phone. It also describes how the buttons on a wired phone for your 
communications system map to the buttons on your MDW 9031. Turn to the information appropriate to your 
communications system:
•PA RT N E R
•MERLIN
•System 25, System 75, System 85, and DEFINITY 
Note:For all systems configured as key systems (for example, PARTNER or 
MERLIN), only three carriers are allowed. For all systems configured as 
PBX systems (for example, DEFINITY), you can use up to five carriers.
