Battery Problems
This is normal operation
for the MDW 9030P
Pocketphone. The Battery icon ap-
pears in the handset
display.No action is required.
Symptom Possible Causes Possible Solutions
Battery power is low.
The Battery icon flashes
in the handset display
and the handset beeps
twice.You have 5 minutes or less of
talk time left. Either:
nComplete your call, turn the
handset off, and recharge the
battery pack.
nIf you have a fully charged
spare battery pack, place your
call on Hold. Swap the battery
packs. Wait 6 to 10 seconds,
then turn the handset on and
proceed as you would for any
call placed on Hold.
The handset battery
pack does not last as
long as it used to under
similar conditions.The battery pack needs to
be refreshed.When the Battery icon flashes,
insert the handset with its
battery into the handset cradle
and press the REFRESH
button, or insert the handset
battery pack into the Spare
battery compartment until the
SPARE LED is steady green (1.5
hours).
The battery pack needs to
be refreshed a second
time.Refresh the battery pack. You get less than 3 hours
of talk time when you use
a battery pack that was
refreshed.

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

Voice Quality Problems
Radio modules are out
of synchronization.For a single-carrier installation, power
down, then repower the carrier.
For a multiple-carrier installation:
1. Verify that all expansion cables are
installed in the correct IN and OUT
jacks.
2. Verify that all expansion cables are fully
inserted into their jacks.
3. Power down, then repower the control
carrier.
4. Power down, 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 radio module antenna is 6–12
inches (15.2–30.5 cm) from the ceiling.
You have a malfunc-
tioning radio module.
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 in a
specific location
is poor and noisy.1. Remove all but one radio module from
the carrier.  (See Removing a Radio
Module from the Carrier in Chapter 4.)
2. Test each radio module individually,
verifying that the POWER
      
 and
      
 PASS
LEDs on each radio module lights when
the carrier is powered.
3. If the PASS LED does not light, the
radio module is malfunctioning.  Re-
place the radio module and handset.

Symptom
Voice quality for calls is
lower than expected.Possible CausesPossible Solutions
You are using different
models of handsets and
the mix is incompatible
with the carrier.
Reinstall the radio module or
carrier away from electrical
equipment and as high as
possible on the wall (but with
radio module antennas 6–12
inches (15.2–30.5 cm) from the
ceiling). See “General Position-
ing Rules” in Chapter 2 for more
information. There are environmental
limitations. The handset antenna is
only partially extended.Fully extend the handset antenna.
See TransTalk 9000 System  in
Chapter 1.
Handset or radio
module is not
working properly.
Place the handset in Wireless
Test Mode and determine signal
strength and voice quality as
described in Chapter 2. Use the
Close-Up Test described in
Performance/Range Test in
Wireless Test Mode in Chapter 3. Volume is too low at
any setting and there
is noise on the line.
The connection
between the radio
module and the
communications
system switch/control
unit is incorrect.
Check the connection between
the radio module and the commu-
nications system switch/control
unit, as described in Chapter 2.
Telephone line may
be producing noise.Report line trouble to your local
phone company.
There was a recent
occurrence of
lightning, or a power
failure.
1. Unplug the carrier(s) power
cord(s) from the electrical
outlet.
2. Wait 10 seconds, then repower
the carrier(s) in order, from left
to right. Your business has two
or more wireless
phones installed and
all handsets seem to
have developed
interference problems
at the same time.

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 9030P
Pocketphone Compatibility,” to reset line
ringing options.
Line ringing options
are incorrectly set for
extensions with radio
modules in the first
expansion carrier. Voice quality for a
call in progress
degrades for more
than 6 seconds
(PARTNER, PART-
NER Plus, PART-
NER II in key
mode, MERLIN,
MERLIN Plus, and
MERLIN II phone
systems only).Refer to Chapter 6, “MDW 9030P
