On A.M. Failure
When this function is turned on, your fax will answer the call after 5 rings if the
answering machine for some reason fails to answer before that time. This
ensures that you will receive fax messages even if the answering machine's
tape fills up or the answering machine is not turned on.
This function has been turned off at the factory. If you want to turn it on, follow
the steps below:
Note: When this function is turned on, make sure that the answering machine
is set to answer on 4 rings or less. If it isn't, the fax will always answer first,
preventing callers from leaving voice messages.
