purpose of the grounding-type plug.

17.Do not overload wall outlets, extension cords or inte- gral convenience receptacles as this can result in a risk of fire or electric shock.

20.Do not permit objects or liquids of any kind to be pushed, spilled and/or fall into the equipment through enclosure openings.

21.Unplug the power cord from the AC power outlet when left unused for a long period of time.

Outdoor Antenna:

18.If an outdoor antenna is connected to the antenna ter- minal, be sure the antenna system is grounded to pro- vide some protection against voltage surges and built up static charge. In the U.S.A., section 810 of the Na- tional Electrical Code, ANSI/NFPA No. 70-1978, pro- vides information on the proper ground for the mast and supporting structure, ground for the lead-in wire to an antenna discharge unit, and size of ground conduc- tors, location of antenna-discharge unit, connection to ground electrode. For ground wire:

A.Use No. 10 AWG (5.3 mm2) copper No. 8 AWG (8.4 mm2) aluminum, No. 17 AWG (1.0 mm2) cop- per-clad steel, bronze, or larger as ground wire.

B.Secure antenna lead-in and ground wires to the house with stand-off insulators spaced from 4 feet (1.2 meters) to 6 feet (1.83 meters) apart.

C.Mount antenna discharge unit as closely as possible to where lead-in enters house.

D.Use jumper wire not smaller than No. 6 AWG (13.3 mm2) copper or equivalent when separate antenna grounding electrode is used.

Care of Equipment:

19.Clean the instrument by dusting with a dry cloth. Un- plug this equipment from the wall outlet and clean the panel with a cloth moistened with a window cleaner.

Do not use liquid cleaners or aerosol cleaners.

Repair of Equipment:

22.Unplug this equipment from the wall outlet and refer servicing to a qualified service personnel under the fol- lowing conditions:

A.The AC power cord or the plug has been damaged.

B.Objects have fallen, or liquid has been spilled into the equipment.

C.The equipment has been exposed to rain or water.

D.The equipment does not operate normally by fol- lowing the operating instructions contained within this owner’s manual. Adjust only those controls that are covered by the operating instructions, as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation.

E.The equipment has been dropped or damaged in any way.

F.The equipment exhibits a distinct change in perfor- mance - this indicates a need for service.

23.Do not attempt to service beyond that described in the operating instructions. All other service should be re- ferred to qualified service personnel.

24.When replacement parts are required, be sure the ser- vice technician has used replacement parts specified by McIntosh or have the same characteristics as the origi- nal part. Unauthorized substitutions may result in fire, electric shock, or other hazards.

25.Upon completion of any service or repairs to this prod-

uct, ask the service technician to perform safety checks to determine that the product is in proper operating condition.
