Problem
You cannot redial by
pressing {REDIAL}.
The unit does not
display the caller's
phone number.
• If the last number dialed was more than 32 digits long,
the number will not be redialed correctly.
• You need to subscribe to a Call Display service.
• Check the AC adaptor is connected to the unit.
• If you receive a call with the Call Display information
while viewing the Caller List, the redial list, the
Phonebook list or the Direct Dial Memory, while
programming or while playing back the message, the
caller's information may not be displayed.
• Other telephone equipment may be interfering with
your phone. Disconnect it and try again.
• Other electrical appliances connected to the same
outlet may be interfering with the Call Display
information.
• Telephone line noise may be interfering with the Call
Display information. Consult your telephone company.
• If your unit is connected to a telephone line with DSL
service, we recommend connecting a noise filter
between the base unit and the telephone line jack.
Contact your DSL provider for details.
