PROBLEM
•
PS becomes out of range.
•
Cannot make calls using
the PS.
•
Noise is frequent while
using the PS.
•
Conversations disconnect
while using the PS.
•
"NO SERVICE" is displayed
on the PS's screen.
•
The CS is not busy (i.e., the
status of the LED is not
Moderate Green Flashing),
but calls cannot be made or
received.
•
There is noise during a
phone call.
•
PS stays out of service
when the CS status is
changed from Out of
Service to In Service.
PROBABLE CAUSE
•
Location of CS is not good.
•
Access system of the PS is
not properly set.
•
Call handover is not
working.
•
PS is out of CS coverage
area.
•
Metallic materials in the
surrounding structure are
interfering with the signal
received by the PS.
•
CSs are located too close
together in the same area.
•
It may take about 20 s for
the CS to start up after the
status has been changed
to In Service.
SOLUTION
•
Locate the CS properly (refer to "5 Site
Survey Using the KX-TCA175/
KX-TCA256/KX-TCA275/KX-TCA355/
KX-TCA364").
•
Change the access system setting of
the PS to the appropriate system or
automatic.
•
Locate the CS properly (refer to "5 Site
Survey Using the KX-TCA175/
KX-TCA256/KX-TCA275/KX-TCA355/
KX-TCA364").
•
Install an additional CS where the
signal interference is worst.
Note
When the PS software version is
3.027 or later, the maximum
number of CSs in an area with a
radio signal strength of "16" is 3 (for
KX-TDA0155)/4 (for
KX-TDA0156)/3 (for KX-TDA0158
with a software version of 6.033 or
later). Also, the maximum number
of simultaneous calls using PSs
may decrease due to wireless
network traffic.
•
Reduce the number of CSs in the area,
or increase the distance between CSs
(refer to "5 Site Survey Using the
KX-TCA175/KX-TCA256/KX-TCA275/
KX-TCA355/KX-TCA364").
•
Wait until the CS starts up.
