Problem Solution
A loud howling sound
occurs when the speaker
is used. • Feedback (a loud howling sound) may occur if you
replace the handset while the speaker is on. To
avoid feedback, turn off the speaker (press )
before you replace the handset.
Auto-dial numbers cannot
be stored in the fax. • Make sure the fax is plugged in and the imaging
film has been loaded. (Auto-dial numbers cannot

See Loading the Imaging Film on page 12.
Nothing appears in the
display. • Make sure the power cord is properly plugged into
a power outlet.
• Connect another electrical appliance to the outlet to

any of its keys. • If a beep sound is not made when you press the
keys, unplug the power cord and then plug it in
again several seconds later.
