1. INSTALLATION
(1) Unpacking
wTo unpack the SFX-32:
1. Open Ihe carton.
2. Remove theaccessories (handset, recording paper roll, etc.) from the carton.
3Remove the faxmachine along with the foam braceson both sides.
4. Remove the polyethylene wrapping around the fax machine.
5. Remove the transportation tapes.
6. Save the carton and the foam braces for later storage and/or shipping.
7. Place the machine where there is access to an AC outlet and amodular phone jack. (Be sure to observe the
precautions below.)
Placement precautlona
●Avoid placing the SFX-32 in humid or dusty places, or in places where it will be exposed to excessive heat
(direct sunlight, heaters, etc.).
●Do not step on or set anything on the AC cord. DAMAGE TO THE AC CORD IS ASAFETY RISK AND CAN
cm3E AFIRE.
●Install the unit only on astable surface.
●Do not connect the SFX-32 to the same AC outlet as appliances that generate large amounts of interference
(heaters with thermostats, appliances with motors, etc.). It is best to use acompletely separate electrical outlet.
QKeep the SFX-32 away from water. If water accidental yenters the unit, unplug the AC power cord immediately.
DO NOT SWITCH THE UNIT ON AGAIN. Contact an authorized Sanyo service center or dealer.
LHandling precaution
●Do not remove any parts that are held in place with screws. (The SFX-32 does not contain any user-serviceable
items).
.Maintain standard room temperature 5°C –35°C (410F –95”F) during use. Do not subject the unit to shock or
vibration. Do not move the unit while it is in use.
.Arapid increase in room temperature in cool weather can cause condensation to form inside the unit. If this
happens, wait at least 15 minutes after turning the unit on before attempting to operate it.
Failure to do so may result in paper jams and/or poor print quality.
●When cleaning the cover or operation panel of the unit, wipe gently using adamp cloth to which asmall amount
of aneutral detergent has been added. NEVER USE SOLVENTS OR CHEMICALLY TREATED CLOTHS.
