GENERAL PRECAUTIONS

WARNING : Do not attempt any maintenance or troubleshooting other than
that mentioned in this manual.

POWER AND GROUNDING

Pay attention to the following :

Power Supply

1. Power requirements:

North America: 115 V, 60Hz
Saudi Arabia: 115 V, 60Hz or
220-240Vac, 50/60 Hz
Other areas: 220-240Vac, 50/60 Hz

2. Insert the power plug securely into the wall

socket.

3. Make sure that the wall outlet is near the

machine and readily accessible.

4. Do not connect other equipment to the same

socket.

5. Do not step on or set anything on the power

cord.

6. Do not connect other equipment to the same

extension cord.

7. Be sure that the power cord is not in a position

where it would trip someone.

Grounding

Ground the machine and the lightning protection circuit in accordance with
regulations. Do not ground to gas or water pipes, or to a telephone ground plug.
Proper grounding is to the ground terminal of the power outlet. Be sure that the
ground terminal of the power outlet is properly grounded.

The lightning protection circuit for the machine requires the machine to be
properly grounded. If proper grounding is provided, about 90% of lightning
damage can be prevented. For safety, be sure to connect the machine to a
three-prong grounded outlet.
