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).

Safety

Important Safety Instructions

1.Read these instructions.

2.Keep these instructions.

3.Heed all warnings.

4.Follow all instructions.

5.Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Clean only with dry cloth.

6.Only use attachments/accessories speciﬁed by the manufacturer.

7.Do not use this product near water.

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.
