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.
H. 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.

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.
