Condition 

Solution

Poor contact 

Clean contact parts thoroughly 

Battery voltage is 
too low 

Start the engine to recharge the 
battery. Replace the battery if 
needed. 

Shutdown on 
overload 

Reduce the wattage of inverter’s load 

Thermal shutdown 

Allow the inverter to cool down by 
reducing the load or turn it off for a 
while.

Receptacle has no 
power

Check the receptacle wiring. 

HINTS

Adding Extension Cord 

If you need extension cord, we recommend the use of an 
extension cord between the AC output of inverter and 
AC appliances.  You may use up to 100 ft. of high quality 
extension cord.  A long cord will result in reduced output 
power.

Buzz in audio system 

Some stereo systems and “boom boxes” will emit a 
buzzing noise from their loudspeakers when operated 
from the power inverter because the power supply in the 
device does not adequately filter the modified sine wave 
produced by the power inverter. The only solution is to 
use a sound system that incorporates a higher quality 
power supply. 

Operating a TV 

Picture tubes have a degaussing coil that uses a high 
initial surge of power to light up the screen from a “cold 
start”.  If the TV does not start up on the first try, switch 
ON the TV every 2 - 3 seconds until the screen comes 
on.  Sometimes, it may take 2-5 tries before starting. 

Television interference 

Operating of the power inverter can interfere with 
television reception on some channels. If this situation 
occurs, the following steps may help to alleviate the 
problem.
1.  Make sure that the chassis ground lug on the back 

of the power inverter is solidly connected to the 
ground system of your vehicles. 

2.  Do not operate high power loads with the power 

inverter while watching television. 

3.

Make sure that the antenna feeding your television 
provides an adequate (“snow free”) signal and that 
you are using good quality cable between the 
antenna and the television.

4.  Move the television as far away from the power 

inverter as possible. 

5.

Keep the cables between the battery and the power 
inverter as short as possible and twist them together 
with about 2 to 3 twists per foot. This minimizes 
radiated interference from the cables.

MAINTENANCE 

Very little maintenance is required to keep the inverter 
operating properly. 

DESCRIPTION 

1000W Peak Power 

— allow you to power appliances 

that require a large amount of initial (peak) power to 
work (such as many TVs and motor-power equipments). 

Low Battery Alarm 

— the inverter sounds an audible 

alarm then turns itself off if the source battery becomes 
too low. 

Auto Shutdown/Reset Protection 

— the inverter 

temporarily shuts itself down to protect itself from 
overheating. 

Overload/Short Circuit Protection 

— the inverter 

automatically turns itself off if the connected load is too 
high or if it shorts. 

Fuse

— the inverter comes with fuse/s already installed 

and easily changed if it is damaged. 

Dual AC Outlets 

— allows you to power up to two 

appliances at the same time.
