DO NOT REMOVE COVER (OR BACK). NO USER
SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.

This symbol warns the user that uninsulated voltage within
the unit may have sufficient magnitude to cause electric
shock. Therefore, it is dangerous to make any kind of contact
with any inside part of this unit.

This symbol alerts the user that important literature concerning
the operation and maintenance of this has been included.
Therefore, it should be read carefully in order to avoid
any problems.

There are special components used in this equipment which are important for safety. These parts are indicated

by the ”

Y ” mark on the schematic diagram and the replacement parts list. It is essential that these critical

parts should be replaced with manufacturer's specified parts to prevent X-radiation, shock, fire, or other hazards.
Do not modify the original design without permission of manufacture.
