Outdoor Antenna:
20. If an outdoor antenna is connected to the antenna ter-

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 mm
2
(8.4 mm ) aluminum, No. 17 AWG (1.0 mm
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.

Repair of Equipment:
24. Refer all servicing to qualified service personnel. Ser-
vicing is required when the equipment has been dam-
aged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen
into the equipment, the equipment has been exposed to
rain or moisture, does not operate normally, or has
been dropped.

operating instructions. All other service should be re-
ferred to qualified service personnel.
26. 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.
27. 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
