CTPhone Handset Problems
Called party can hear you but cannot be heard
Conversation broken up
Handoff clicks occur during conversation
The handset signal strength is inadequate. Try moving closer to a base
station. If the problem is reported by many individuals, try moving the base
station to a location that provides better coverage.
For best results the signal strength icon should show three to five bars.
The Bit Error Rate (BER) test should report Good or Max results. (See
page 5-14 for instructions on how to perform this test.)
Display does not contain date, time and signal strength
The handset is not locked onto a base station. Try powering off and power-
ing on the handset or moving to another location closer to a base station.
Note that sometimes it may take up to a minute for the full display to
appear.
If the problem persists, check system and handset ID configuration in the
CTPhone Controller and handset.
These symptoms may also occur if the CTPhone Controller or base station
is being reset.

The handset’s ESN may be improperly configured in the CTPhone Con-
troller. To fix this problem, complete the following steps:
1 Reprogram the handset with proper system and handset IDs.
2 Get the User database from the CTPhone Controller and change the
handset ID configured for the handset to any valid ID not already in
use. Send the change to the CTPhone Controller.
3 Change the handset ID in the User database to match the ID pro-
grammed in the handset. Send the change to the CTPhone Controller.
4 Make a call on the handset to store its ESN in the CTPhone Controller.
5 Save and back up the databases.
Invalid ESN reported for handset (alarm)
The same handset ID and system ID were programmed into two phones
and the databases on the CTPhone Controller, and the handset ESNs
