d) The appliance does not appear to operate normally or  
exhibits a marked change in performance; or  
e) The appliance has been dropped, or the enclosure is  
damaged.  
2. RETAIN INSTRUCTIONS  
The safety and operating instructions should be retained for  
future reference.  
3. HEED WARNINGS  
All warnings on the appliance and in the operating instructions  
should be adhered to.  
4. FOLLOW INSTRUCTIONS  
17. POWER LINES  
(APPLIES TO TUNER AND RECEIVERS ONLY)  
All operating and use instructions should be followed.  
5. WATER AND MOISTURE  
An outdoor antenna should be located away from power lines.  
18. OUTDOOR ANTENNA GROUNDING  
(APPLIES TO TUNER AND RECEIVERS ONLY)  
The appliance should not be used near water - for example,  
near a bathtub, washbowl, kitchen sink, laundry tub, in a wet  
basement, or near a swimming pool, etc.  
If an outside antenna is connected to the receiver, be sure 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 discharge unit, size of grounding  
conductors, location of antenna-discharge unit, connection to  
grounding electrodes, and requirements for the grounding  
electrode. See Figure.  
6. CARTS AND STANDS  
The appliance should be used only with a cart or stand that is  
recommended by the manufacturer.  
PORTABLE CART WARNING  
6A.An appliance and cart combination should be  
moved with care. Quick stops, excessive force,  
and uneven surfaces may cause the appliance  
and cart combination to overturn.  
a) Use No. 10 AWG (5.3 mm2) copper, No. 8 AWG (8.4 mm2)  
aluminum, No. 17 AWG (1.0 mm2) copper-clad steel or  
bronze wire, or larger, as a ground wire.  
b) Secure antenna lead-in and ground wires to house with  
stand-off insulators spaced from 4-6 feet (1.22-1.83 m)  
apart.  
7. WALL OR CEILING MOUNTING  
S3125A  
This equipment is not designed for use mounted on a wall or a  
ceiling.  
8. VENTILATION  
The appliance should be situated so that its location or position  
does not interfere with its proper ventilation. For example, the  
appliance should not be situated on a bed, sofa, rug, or similar  
surface that may block the ventilation openings, or placed in a  
built-in installation, such as bookcase or cabinet that may  
impede the flow of air through the ventilation openings.  
c) Mount antenna discharge unit as close as possible to where  
lead-in enters house.  
d) Use jumper wire not smaller than No.6 AWG (13.3 mm2)  
copper, or the equivalent, when a separate antenna-  
grounding electrode is used. See NEC Section 810-21(j).  
9. HEAT  
Antenna Grounding According to  
the National Electrical Code  
The appliance should be situated away from heat sources  
such as radiators, heat registers, stoves, or other appliances  
(including amplifiers) that produce heat.  
10. POWER SOURCES  
The appliance should be connected to a power supply only of  
the type described in the operating instructions or as marked  
on the appliance.  
Antenna Lead  
In Wire  
11. POWER-CORD PROTECTION  
Power-supply cords should be routed 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 appliance
