• Make sure that the correct center number is entered
(see page 85) .
When your SMS center calls your fax machine, the
machine checks to see if the SMS center number sent
by Caller ID matches the center incoming number
entered as explained on page 85. If the numbers don't
match, the fax machine does not begin SMS
reception and simply rings instead. If you have turned
on the Caller ID function (see page 136), the correct
center number sent by Caller ID will appear in the
display (and in the Caller ID list). Check this number
against your entered center number and correct the
latter if needed.
• To receive SMS messages, you must subscribe to a
Caller ID service.
• Is the inbox full? If so delete one or more messages
(see page 83).
• Is the SMS Receive function turned on? This function
must be turned on to receive SMS messages (see
page 84).
• The maximum number of digits that can be entered
for the number of an SMS message recipient is 20. A
number longer than 20 digits cannot be used when
redialing, using an auto-dial number, or using the
Caller ID list.
• The maximum number of characters that can be
entered when writing an SMS message is 160. Less
characters can be entered if the message includes
special symbols or characters that require more
memory space.
