Important Precautions and Safety Information
When using this machine, these basic safety precautions should always be 
followed to reduce risk of fire, electric shock and injury to people:
1. Read and understand all instructions.
2. Use common sense whenever operating electrical appliances.
3. Follow all warnings and instructions marked on the machine and in the 
literature accompanying the machine.
4. If an operating instruction appears to conflict with safety information, 
heed the safety information. You may have misunderstood the operating 
instruction. If you cannot resolve the conflict, contact your sales or 
service representative for assistance.
5. Unplug the machine from the AC wall socket and/or telephone jack 
before cleaning. Do not use liquid or aerosol cleaners. Use only a damp 
cloth for cleaning.
6. Do not place the machine on an unstable cart, stand or table. It may fall, 
causing serious damage.
7. Your machine should never be placed on, near or over a radiator, heater, 
air conditioner or ventilation duct.
8. Do not allow anything to rest on the power. Do not locate your machine 
where the cords will be abused by persons walking on them.
9. Do not overload wall outlets and extension cords. This can diminish 
performance, and may result in the risk of fire or electric shock.
10. Do not allow pets to chew on the AC power, telephone or PC interface 
cords.
11. Never push objects of any kind into the machine through case or cabinet 
openings. They may touch dangerous voltage points, creating a risk of 
fire or shock. Never spill liquid of any kind onto or into the machine.
12. Your machine may have a heavy cover for optimal pressure on the 
document for the best scanning and/or faxing (usually the flatbed-type 
machine). In this case, replace the cover after placing document on the 
scan glass, by holding and moving it down slowly until it seats on its 
location.
13. To reduce the risk of electric shock, do not disassemble the machine. 
Take it to a qualified service technician when repair work is required. 
Opening or removing covers may expose you to dangerous voltages or 
other risks. Incorrect reassembly could cause electric shock when the 
unit is subsequently used. 
14. Unplug the machine from the telephone jack, PC and AC wall outlet and 
refer servicing to qualified service personnel under the following 
conditions:
•When any part of the power cord, plug or connecting cable is damaged 
or frayed.
•If liquid has been spilled into the machine. 
•If the machine has been exposed to rain or water.
•If the machine does not operate properly after instructions have been 
followed.
•If the machine has been dropped, or the cabinet appears damaged.•If the machine exhibits a sudden and distinct change in performance.
15. Adjust only those controls covered by the operating instructions. 
Improper adjustment of other controls may result in damage, and may 
require extensive work by a qualified service technician to restore the 
machine to normal operation.
16. Avoid using this machine during a lightning storm. There may be a 
remote risk of electric shock from lightning. If possible, unplug the AC 
power and telephone cord for the duration of the lightning storm.
17. SAVE THESE INSTRUCTIONS.
18. Use only No.26 AWG or larger telephone line cord.

the following two conditions: 
•This device may not cause harmful interference, and 
•This device must accept any interference received, including 
interference that may cause undesired operation.
Downloaded From ManualsPrinter.com Manuals 
						

							9
This equipment has been tested and found to comply with the limits for a 
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are 
designed to provide reasonable protection against harmful interference in a 
residential installation. This equipment generates, uses and can radiate radio 
frequency energy and, if not installed and used in accordance with the 
instructions, may cause harmful interference to radio communications. 
However, there is no guarantee that interference will not occur in a particular 
installation. If this equipment does cause harmful interference to radio or 
television reception, which can be determined by turning the equipment off 
and on, the user is encouraged to try to correct the interference by one or 
more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to 
which the receiver is connected.
•Consult the dealer or experienced radio TV technician for help.
CAUTION: Change or modifications not expressly approved by the 
manufacturer responsible for compliance could void the users authority to 
operate the equipment.
Canadian Radio Interference Regulations
This digital apparatus does not exceed the Class B limits for radio noise 
emissions from digital apparatus as set out in the interference-causing 
equipment standard entitled “Digital Apparatus”, ICES-003 of the Industry 
and Science Canada.
Cet appareil numérique respecte les limites de bruits radioélectriques 
applicables aux appareils numériques de Classe B prescrites dans la norme 
sur le matériel brouilleur: “Appareils Numériques”, ICES-003 édictée par 
l’Industrie et Sciences Canada.
Fax Branding
The Telephone Consumer Protection Act of 1991 makes it unlawful for any 
person to use a computer or other electronic device to send any message via 
a telephone facsimile machine unless such message clearly contains in a 
margin at the top or bottom of each transmitted page or on the first page of 
the transmission the following information:
(1) the date and time of transmission
(2) identification of either business, business entity or individual sending the 
message; and
(3) telephone number of either the sending machine, business, business 
entity or individual.
The Telephone Company may make changes in its communications facilities, 
equipment operations or procedures where such action is reasonably 
required in the operation of its business and is not inconsistent with the rules 
and regulations in FCC Part 68. If such changes can be reasonably expected 
to render any customer terminal equipment incompatible with telephone 
company communications facilities, or require modification or alteration of 
such terminal equipment, or otherwise materially affect its use or 
performance, the customer shall be given adequate notice in writing, to allow 
the customer an opportunity to maintain uninterrupted service.
Ringer Equivalence Number
The Ringer Equivalence Number and FCC Registration Number for this 
machine may be found on the label located on the bottom or rear of the 
machine. In some instances you may need to provide these numbers to the 
telephone company.
The Ringer Equivalence Number (REN) is a measure of the electrical load 
placed on the telephone line, and is useful for determining whether you have 
“overloaded” the line. Installing several types of equipment on the same 
telephone line may result in problems making and receiving telephone calls, 
especially ringing when your line is called. The sum of all Ringer Equivalence 
Numbers of the equipment on your telephone line should be less than five in 
order to assure proper service from the telephone company. In some cases, 
a sum of five may not be usable on your line. If any of your telephone 
equipment is not operating properly, you should immediately remove it from 
your telephone line, as it may cause harm to the telephone network.
WARNING:
FCC Regulations state that changes or modifications to this equipment not 
expressly approved by the manufacturer could void the user’s authority to 
operate this equipment. In the event that terminal equipment causes harm 
to the telephone network, the telephone company should notify the customer 
that service may be stopped. However, where prior notice is impractical, the 
company may temporarily cease service, providing that they:
a) promptly notify the customer.
b) give the customer an opportunity to correct the equipment problem.
c) inform the customer of the right to bring a complaint to the Federal 
Communication Commission pursuant to procedures set out in FCC Rules and
