lightning flash with arrowhead, within

an equilateral triangle, is intended to

alert the user to the presence of unin-

stalled “dangerous voltage” within the

product’s enclosure that may be of risk

of electric shock to persons.

The exclamation point within an

equilateral triangle is intended to

alert the user to the presence of

important operating and mainte-

nance (servicing) instructions in the

literature accompanying the appli-

12  Only use attachments/accessories specified

by the manufacturer.

13  Do not attempt to move this apparatus until

after it has been turned of and cooled down

to room temperature.

14  Unplug this apparatus during lighting storms

or when unused for long periods of time.

15  Refer all servicing ot  qualified service per-

sonnel.  Servicing is required when the ap-

paratus has been damaged in any way, such

as power-supply cord or plug is damaged,

liquid has been spilled or objects have fallen

into the apparatus, the apparatus has been

exposed to rain or moisture, does not oper-

ate normally, or has been dropped.

16  Do not expose this equipment to dripping or

splashing and ensure that no objects filled

with liquid, such as vases, are placed on or

near the equipment.

supply cord from the A.C. receptacle.

18  The mains plug of the power supply cord

shall remain readily operable.

19  Never touch a vacuum tube while it is oper-

ating.  Some can reach temperatures of al-

most 400 degrees F.

20  Turn apparatus off when not in use.
