Note: If you cannot send and receive faxes, ensure that you are connected to an approved analog 
telephone line. The fax cannot send or receive when connected directly to a digital telephone line 
without the use of an analog filter. It can also require you to set the fax starting rate to Forced 
(4800 bps). For details, see Selecting the Starting Rate on page 141.
