Care and Maintenance
• Keep the amplifier dry; if it gets wet, wipe it dry immediately.
• Use and store the amplifier only in normal temperature environments.
• Handle the amplifier carefully; do not drop it.
• Keep the amplifier away from dust and dirt, and wipe it with a damp cloth
occasionally to keep it looking new.
• Modifying or tampering with the amplifier’s internal components can
cause a malfunction and might invalidate its warranty. If your amplifier
is not performing as it should, take it to your local
RadioShack
store for
assistance.
Replacing the DC Power Cord’s Fuse
If the amplifier does not operate from a 12V battery source, check the fuse in
the DC power cord plug. If the fuse is blown, remove the cap of the plug and
replace the fuse with one of the proper type and rating (6A, 250V).
Important Safety Instructions

8.
Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer or sold with the apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury from tip-over.
9.
Exercise caution when moving any product and cart combination. Quick
stops, excessive force, and uneven surfaces may cause the appliance and cart
combination to overturn.
10. Slots and openings in the cabinet are provided for ventilation and to ensure
reliable operation of the product and to protect it from overheating. Do not block
any ventilation openings. Install in accordance with the manufacturer’s instructions.
11. Use only the type of power source indicated on the label. If you are not sure of the
type of power supply to your home, consult your product dealer or local power
company. For products intended to operate on battery power, or other sources,
refer to the operating instructions.
12. Do not defeat the safety purpose of the polarized or grounding-type plug. A
polarized plug has two blades with one wider than the other. A grounding type
plug has two blades and a third grounding prong. The wide blade or the third
prong are provided for your safety. If the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.
Alternate Warnings:
This product is equipped with a three-wire grounding-type
plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-
type power outlet. This is a safety feature. If your are unable to insert the plug into
the outlet, contact your electrician to replace your obsolete outlet. Do not defeat
the safety purpose of the grounding-type plug.
13. Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.
14.
Protective Attachment Plug:
The product is equipped with an attachment
plug having overload protection. This is a safety feature. See Instruction Manual
for replacement or resetting of protective device. If replacement of the plug is
required, be sure the service technician has used a replacement plug specified by
the manufacturer that has the same overload protection as the original plug.
15. 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. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides
information with regard to proper grounding of the mast and supporting structure,
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.
16. Unplug this apparatus during lightning storms or when unused for long periods of
time.
