pinched by items placed upon or against them, paying particular attention to cords at plugs,
convenience receptacles, and the point where they exit from the instrument.

7. Ventilation - Locate the instrument for proper ventilation. For example, the instrument should not
be placed on a bed, sofa, rug, or similar surface that may block ventilation openings; or, placed

in a built-in installation, such as a bookcase or cabinet, that may impede the flow of air through

the ventilation openings.

8. Heat - Locate the instrument away from heat sources such as radiators, heat registers, stoves, or
other appliance (including amplifiers) that produce heat.

9. Wall or Cabinet Mounting - Mount the instrument in a wall or cabinet only as described in the owner's

manual.

kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc.

11. Cleaning - Clean the instrument by dusting with a dry cloth. Clean the panel with a cloth moistened

with a window cleaner.

12. Object and Liquid Entry - Do not permit objects to fall and liquids to spill into the instrument through
enclosure openings.

13. Nonuse Periods - Unplug the power cord from the AC power outlet when left unused for a long period
of time.

14. Damage Requiring Service - Service must be performed by qualified service personnel when:
A. The power supply cord or the plug has been damaged; or
B. Objects have fallen, or liquid has been spilled into the instrument; or
C. The instrument has been exposed to rain; or

D. The instrument does not appear to operate normally or exhibits a marked change in performance;

15. Servicing - Do not attempt to service beyond that described in the operating instructions. All other
service should be referred to qualified service personnel.

16. Grounding or Polarization - Do not defeat the inherent design features of the polarized plug. Non­polarized line cord adaptors will defeat the safety provided by the polarized AC plug.
