Try altering the position of the inverter, antenna cables, and television power cord. 2.
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
4.
Line Filters can be purchased at most electronic supply stores.
Try grounding the inverter with a minimum 18 gauge (AWG) (0.75mm
5. 2 ) wire, using as
short a length as possible.
NOTE: 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’s power supply.
Unfortunately, this problem can only be resolved by purchasing a sound system with a higher
quality power supply or higher quality filter.
POWER SOURCE 8.
When operating a device that draws approximately 60 watts, your average automobile
or marine battery at full charge will provide an ample power supply to the inverter for
approximately 3 hours when the engine is off. The actual length of time the inverter will
function depends on the age and condition of the battery and the power demand being placed
by the device being operated with the inverter.
If you decide to use the inverter while the engine is off, we recommend you turn OFF the
device plugged into the inverter before starting the engine. To maintain battery power, start
the engine regularly and let it run for approximately 15 to 20 minutes to recharge the battery.
Although it is not necessary to disconnect the inverter when turning over the engine, it may
briefly cease to operate as the battery voltage decreases. While the inverter draws very low
amperage when not in use, it should be unplugged to avoid battery drain.
LED INDICATOR AND SHUTDOWN PROTECTION 9.
The Green LED lights automatically when then inverter is plugged into a 12 volt DC power
source and is turned on. The Red LED lights, the alarm sounds and the inverter automatically
turns itself off under the following conditions:
When the power input from the vehicle’s battery drops to approximately 10.5 volts, low 1.
battery shutdown occurs and the inverter shuts off. Solution: Recharge or Replace the
battery.
When the power input from the vehicle’s battery exceeds 15 volts, high voltage overload
2.
protection occurs. Solution: Reduce the voltage range to between 12 volts and 14 volts.
The continuous load demand from the equipment or device being operated exceeds
3.
the continuous load rating of the inverter being used. Solution: Use a higher capacity
inverter or lower rated device.
The case temperature becomes hot (exceeds 145°F). Solution: Allow the inverter to
4.
cool. Do not block the cooling slots or air flow over and through the inverter. Reduce the
load on the inverter to the continuous rated output.
RESET: To reset after shutdown occurs, switch the inverter On/Off switch to the OFF (O)
position. Check the source of the problem and correct. Switch the inverter On/Off switch to
the ON (I) position.
IF THE INVERTER FUSE BLOWS 10.
The power inverter is fitted with fuses, which should not have to be replaced under normal
operating conditions. A blown fuse is usually caused by reverse polarity or a short circuit
within the device or equipment being operated.
If the fuses blow:
The fuse is not user replaceable; take the inverter to a qualified service person. (Call 1.
