the phone number may not match the number you
put in the memory.

line access digit on a speed dialing key or in the

Private Branch Exchange (PBX), the phone number
will not match the Caller ID data.

waiting service (page 61).
• If you move or change your telephone company, reset
this phone (page 62).
