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.
7. Wall or Ceiling Mounting  The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer.
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 a bookcase or cabinet that may impede the flow of air through the ventilation openings.
9. Heat  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 of the type described in the operating instructions or as marked on the appliance.
11. Grounding or Polarization  Observe the precautions that should be taken so that the grounding or polarization protective features of an appliance are not defeated.
12. 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.
13A. Cleaning  The appliance should be cleaned only as recommended by the
manufacturer.
13B. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
14. Power Lines  An outdoor antenna should be located away from power lines.
15. Outdoor Antenna Grounding  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 801 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 electrodes, and requirements for the grounding electrode. See Figure 73.1.
16. Nonuse Periods  The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time.

EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810-
RADIO AND TELEVISION EQUIPMENT
a. Use No. 10 AWG (5.3 mm2) copper, No. 8 AWG (8.4 mm2) aluminium, 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 wire to house with stand-off insulators
spaced from 4 - 6 feet (1.22 - 1.83 m) apart.
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 m 2) copper, or the
equivalent when a separate antenna-grounding electrode is used. See NEC Section 810 - 21 (i).

Battery Operation
 Remove Battery Compartment Cover.  Put in 10 batteries (UM-2 or equivalent) in correct polarity as indicated inside the
compartment.  Replace the cover. Note: Check your batteries regularly, old or discharged batteries should be replaced.
If the unit is not going to be used for some time or is being run exclusively on alternative power, remove the batteries to avoid leakage and damage.
High power batteries only should be used to operate this unit
AC Mains Power Operation
Take the supplied AC adaptor cord and connect the corresponding end to the DC Socket and household mains power outlet. Make sure the voltage is compatible. Note: If you plug the AC adaptor cord off from the AC Socket and from the unit,
the unit will operate with battery power.

RADIO OPERATION
 Press the Power Switch down to turn on the unit and the Power indicator light up.  Set Function Selector to RADIO position.  Select the desired radio frequency band with Band Selector. For FM Stereo, FM
Stereo LED light on. Rotate Tuning Control to set the Dial Pointer against the station frequency as
marked on the dial scale. Adjust Volume Control to the desired volume level.
ANTENNA
For FM stations, extend the Telescopic Antenna to full length, adjust the angle and direction for the best reception. However, medium wave signals are picked up through the built-in ferrite antenna. You may have to orient the set to obtain the clearest reception.
TV OPERATION
 Press the Power Switch down to turn on the unit.  Set Function Selector to TV position.  Select the desired TV frequency band with Band Selector.  Rotate Tuning Control to set the Dial Pointer against the station frequency as
marked on the dial scale.  Adjust Volume Control to the desired level. Adjust V-HOLD, BRIGHTNESS and CONTRAST on back to the desired level.
EXTERNAL ANTENNA
If desired you may hook up an outdoor antenna to your portable TV set, which will give you greater range and clearer reception for the channels which are difficult to receive with the built-in antenna. To hook up the outdoor antenna, just connect the VHF or UHF antenna to the Antenna Adaptor (included in your set), and then connect the Antenna Adaptor to the External Antenna Jack. Note: When the antenna adapter is plugged into the external antenna jack, the
telescopic antenna is automatically disconnected.
WEATHER BAND AND ALERT OPERATION
 Set Function Selector to WB position.  Select the appropriate Weather Band frequency with Weather Channel Band
Selector for the best reception.  Adjust Volume Control to the desired level.  Set Function Selector to ALERT position in standby stage for ALERT operation.  Pre-set WB channel will switch on to alert emergency weather with Beep sound.
PRIVATE LISTENING (EARPHONE)
An earphone jack is provided for your private listening enjoyment when the earphone plug is inserted into the jack. The internal speaker is automatically disconnected. Note: The jack is designed to permit the use of 3.5mm plug earphone only.
