this, some interference may occur with

your television picture, especially with

weak signals. Below are some sugges-

tions to try and improve reception.

Make sure the television antenna

produces a clear signal under normal

operating conditions (i.e., at home

plugged into a standard 110V AC wall

outlet). Also, ensure that the antenna

cable is adequately shielded and of

good quality.

Try altering the positions of the inverter,

antenna cables, and television power

cord. Add an extension cord from the

inverter to the TV so as to isolate its

power cord and antenna cables from

the 12-volt power source.

Try coiling the television power cord

and the input cables running from the

12 -volt power source to the inverter.

Affix one or several "Ferrite Data Line

Filters" to the television power cord.

Ferrite Data Line Filters can be pur-

chased at most electronic supply stores

including Radio Shack - Part Number

273-105.

Attention: You may hear a "buzzing"

sound being emitted from inexpensive

sound systems when operated with the

inverter. This is due to ineffective filters

in the sound system. This problem

can only be resolved by purchasing

a sound system with a higher quality

power supply.

BloWn fUSe

A blown fuse is usually caused by re-

verse polarity or a short circuit within

the device or equipment being oper-

ated.

If the fuse blows, take the inverter to a

qualified technician for repair.

Your average automobile or marine bat-

tery will provide an ample power sup-

ply to the inverter for 30 to 45 minutes

even when the engine is off. The actual

length of time the inverter will function

depends on:
1. Age and condition of the battery.
2. Power demand being placed by the

equipment being operated with the

inverter.

If you decide to use the inverter while

the engine is off: turn OFF the device

plugged into the inverter before start-

ing the engine. Start the engine every

hour and let it run for approximately 10

minutes to recharge the battery.

Attention: Although it is not necessary

to disconnect the inverter when starting

the engine, it may briefly cease to oper-

ate as the battery voltage decreases.

When the inverter is not supplying

power, it draws a very low amperage

from the battery. The inverter may be

left connected to the battery for up to

three hours. It is recommended that the

inverter always be disconnected when

not in use.

SAfeTy feATUreS

The LED Indicator light will turn from

GREEN to RED and the inverter will

automatically turn itself off when:
1. The power input from the battery

drops to approximately 10 volts.

(When the power input drops to

approximately 10.5 volts, an alarm

will sound for an extended period).

2. The power input from the battery

exceeds 15.5 volts.

3. The continuous load demand from

the equipment or device being

operated exceeds 2000 watts.
