RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK, 
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.

T

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

by the ”

” 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.

PCBs (manufactured) using lead free solder (PbF) will have a stamp on the PCB.
