Recording an Outgoing Message
To listen to or erase an outgoing message
To listen to or erase an outgoing message, follow Steps 1 through 4 of
the above procedure to select the message, and then press the
PLAY/SKIP key to listen to it, or the DELETE key to erase it. To
return to the date and time display, press the STOP key twice. Note
that the general outgoing message cannot be erased. If you need to
change it, simply repeat the recording procedure.
Note: If an extension phone is connected to the UX-460, an outgoing
message cannot be recorded, played, or deleted while the extension phone
is being used (while LINE IS IN USE appears in the display).
