CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

Warning: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture.

Read all the safety and operating instructions before connecting or using this unit.

Retain this notice and the owner’s manual for future reference.

All warnings on the unit and in the operating instructions should be adhered to.

Even when the light of the switch is off, some parts of the appliance may still be under hazardous live potential.

Do not use this unit near water: for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool.

Do not place any object filled with liquids, such as vases, on the unit.

The AC power cord should be routed so that it is not likely to be walked on or pinched, especially near the plug, convenience receptacles, or where the cord exits the unit.

The AC power cord should be unplugged from the wall outlet when the unit is to be unused for a long period of time.

This unit should be serviced by qualified service personnel when:

—The power cord or plug has been damaged; or —Objects have fallen or liquid has been spilled,

into the unit; or

—The unit does not appear to operate normally, or exhibits a marked change in performance; or

—The device has been dropped, or the enclosure damaged.

All warnings on the unit and in its operating instruc- tions should be adhered to.

The unit should be installed so that its location or position does not interfere with its proper ventila- tion. For example, it should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or placed in a built-in installa- tion, such as a bookcase or cabinet, that may

impede the flow of air through its ventilation openings.

The unit should be situated away from heat sources and open flames such as radiators, heat registers, stoves, or other devices (including amplifiers) that produce heat.

The unit should be connected to a power-supply outlet only of the voltage and frequency marked on its rear panel.

Care should be taken so that objects do not fall, and liquids are not spilled, into the enclosure openings.

If necessary, the user should consult the dealer or an experienced radio/television technician for addi- tional suggestions. The user may find the following booklet prepared by the Federal Communications Commission helpful: “How to identify and Resolve Radio - TV Interference Problems.” This booklet is available from the US Government Printing Office, Washington, D.C., 20402, Stock No. 004-000-00345-4.

Outdoor Antenna Grounding

If any outside antenna is connected to your tuner or tuner-preamplifier, be certain the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna dis- charge unit, size of the grounding conductors, location of the antenna dis-charge unit, connection to grounding electrodes, and requirements for the grounding electrode.

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 or bronze wire, or larger, as a ground wire.

b. Secure antenna lead-in and ground wires to house with standoff insulators spaced 4-6 feet (1.22- 1.83 m) apart.

c. Mount antenna discharge unit as close as possi- ble to where lead-in enters house.

d. Use jumper wire not smaller than No. 6 AWG (13.3 mm 2 ) copper, or the equivalent, when sepa- rate antenna-grounding electrode is used. See NEC Section 810-21 (j).

Note to CATV system installer:

This reminder is provided to call the CATV system installer’s attention to Article 820-22 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
