The components designated by a symbol ( ! ) in this schematic diagram designates components whose value are of
special significance to product safety. Should any component designated by a symbol need to be replaced, use only the part
designated in the Parts List. Do not deviate from the resistance, wattage, and voltage ratings shown.
CAUTION : Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer's instructions.
NOTE : 1. Parts order must contain model number, part number, and description.
2. Substitute parts may be supplied as the service parts.
3. N. S. P. : Not available as service parts.
Design and specification are subject to change without notice.
