THESE INSTRUCTIONS ARE TO PRO-
TECT YOU AND THE MclNTOSH IN-
STRUMENT. BE SURE TO FAMILIARIZE
YOURSELF WITH THEM.
1. Read all instructions - Read the safety and
operating instructions before operating the
instrument.
2. Retain Instructions - Retain the safety and
operating instructions for future reference.
3. Heed warnings - Adhere to warnings and
operating instructions.
4. Follow Instructions - Follow all operating and use
instructions.
WARNING: TO REDUCE RISK OF FIRE OR
ELECTRICAL SHOCK, DO NOT EXPOSE THIS
INSTRUMENT TO RAIN OR MOISTURE.
5. Power Sources - Connect the power supply only to
the type described in the operating instructions or
as marked on the unit.
6. Power-Cord Protection - Route power-supply cords
so that they are not likely to be walked on or
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
owners manual.
10. Water and Moisture - Do not use the instrument
near water - for example, near a bathtub,
washbowl, 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. Power Lines - Locate any outdoor antenna away
from power lines.
14. Outdoor Antenna Grounding - If an outdoor
antenna is connected to the antenna terminal, be
sure the antenna system is grounded to provide
some protection against voltage surges and built
up static charge.
In the U.S.A., section 810 of the National Electrical
Code, ANSI/NFPA No. 70-1987, provides
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 conductors, location of antenna-discharge
unit, connection to grounding electrodes, and
requirements for the grounding electrode.
For ground wire:
a) Use No. 10 AWG (5.3 mm
2
) copper No. 8 AWG
(8.4 mm
2
) aluminum, No. 17 AWG (1.0 mm
2
)
copper-clad steel, bronze wire, or larger as ground
wire.
b) Secure antenna lead-in and ground wires to
house with stand-off insulators spaced from 4 feet
(1.22 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 mm
2
) copper or equivalent when separate
antenna grounding electrode is used.
