Problem
Cause/solution
I cannot dial the phone number
edited in the caller list.
R
The phone number you dialed might have been edited
incorrectly (for example, the long distance “1” or the area
code is missing). Edit the phone number with another
pattern (page 48).
Time on the unit has shifted.
R
Incorrect time information from incoming Caller ID
changes the time. Set the time adjustment to
“
Manual
”
(off) (page 36).
The 2nd caller’s information is
not displayed during an outside
call.
R
In order to use Caller ID, call waiting, or Call Waiting
Caller ID (CWID), you must first contact your phone
service provider and subscribe to the desired service.
After subscribing, you may need to contact your phone
service provider again to activate this specific service,
even if you already subscribed to both Caller ID and Call
Waiting with Caller ID services (CWID).

The answering system will not answer incoming calls
while the other devices such as headset or handsets are
engaged in a call.
