Cause/solution
R You dialled a call restricted number (page 31).
R The key lock feature is turned on. Turn it off (page 19).
R The unit is not designed to be used with rotary/pulse dialling
services.
Cause/solution
R You must subscribe to a Caller ID service. Contact your
service provider/telephone company for details.
R If your unit is connected to any additional telephone
equipment, remove and plug the unit directly into the wall
socket.
R If you use a DSL/ADSL service, we recommend connecting a
filter (contact your DSL/ADSL service provider) to the
telephone line between the base unit and the telephone line
socket. Contact your DSL/ADSL provider for details.
R Other telephone equipment may be interfering with this unit.
Disconnect the other equipment and try again.
R Depending on your service provider/telephone company, the
unit may display the caller's information at the 2nd ring or later.
Set the first ring to "Off" (page 26).
R Move closer to the base unit.
R Incorrect time information from incoming Caller ID changes the
time. Set the time adjustment to "Manual" (off) (page 26).
R Edit the phonebook entry name to fit in 1 line of text (page 21).
Cause/solution
R The answering system is turned off. Turn it on (page 36).
R The message memory is full. Erase unwanted messages
(page 37).
R The recording time is set to "Greeting Only". Change the
setting (page 42).
R If you subscribe to a voice mail service, messages are
recorded by your service provider/telephone company, not
your telephone. Change the unit's number of rings setting or
contact your service provider/telephone company (page 41).
