■
Handset range and
voice quality are not
as good as they
were before.

any setting and there
is noise on the line.
Possible Causes
There are environmental
limitations.
A competing radio device
may have been installed in
the area.

■
■
Handset or radio module
may not be working
properly.
The connection between
the radio module or

producing noise.
Possible Solutions
Reinstall the radio module
or carrier assembly as
high as possible on the
wall and away from metal
obstructions.
Eliminate any possible
interfering devices (micro-
waves) between the radio
module or carrier assembly
and your handset.
Turn off or unplug nearby
equipment (computer,
modem) to see if it is
causing interference. If it
is, make sure it is on a dif-
ferent power line or move
it further away from the
handset, radio module, or
carrier assembly.
Place the handset in
Wireless Test Mode as
described on page 10. 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.

■
■
Place the handset in
Wireless Test Mode and
determine sound clarity as
described on page 10. If
the dial tone is clear and
strong, the handset and
radio module are OK.
Check the connection
between the radio module
or carrier assembly and
the switch/control unit.
Report line trouble to your

On MERLIN II and MERLIN LEGEND systems, you must
connect your wireless phone to an available jack on either a
408 outside line/analog telephone module or a 008 analog
telephone module.

You must disable the Voice Announce feature. This phone
does not have a speaker function.
The wireless phone should not be assigned to a paging
group.
To program the Ringing Option feature, use the “arrow” and
“rectangle” indicators in the display as the equivalent of red
and green LEDs, respectively.
For MERLIN II system users, if you program an Auto Intercom
button, idle line preference must be set to intercom.
If any of your incoming lines has the call waiting feature,
program the Recall feature on one of the programmable
buttons and press it before you pick up a waiting call. You
can dial #50 before you pick up a waiting call on the follow

Either a TN762B Hybrid pack or a ZTN79 ATL pack must be
used to connect the switch and the MDW 9000 telephone.
Assigning features may be done only by the system
administrator.
Use the following features with caution:
Automatic Intercom, Bridging, Coverage, Direct Station
Selection, Personal Line, Pooled Facility, Send All Calls
(use with single ring reminder).
Since these features provide visual indication that the
feature is on, be aware that if you turn off the handset when
using that feature, you may forget that the feature is on.
Do not assign the following features: Auto Answer, Scroll,
Inspect, Directory, Next, Local, Call, and Manual Callback
Queuing.
If programming the Flex DSS or Repertory Dial feature, dial
the number to be recorded and push the button you are
assigning to the feature. You will receive 3 short beeps and
a dial tone to confirm programming.
If you are programming numbers for the Station Speed Dial
feature, dial the numbers to be stored then dial the Per-
sonal Speed Dialing code (#20 through #39), including the
