Using visual message waiting service (continued)
If you move or change your telephone company
Message waiting signals are sent in one of two ways: FSK signaling or
“stutter” signaling (Your telephone company can provide you with
more information about your service).
The first time this phone receives a voice mail message, it will set itself
to the FSK service and will lock out the stutter service if your
telephone company is in FSK service.
When you move or change your telephone company, you need to do
the following: Unplug the AC power adaptor, and plug it into an AC
outlet. If the battery is still inserted in the phone, take it out. The phone
will return to the ready state for either FSK or stutter dial tone voice
mail recognition.
