Troubleshooting Tips

1.

If the low battery alarm sounds, this means that the input voltage is below the

necessary 10.5 V.  The battery needs recharging.  You should stop using the
appliance and then recharge the battery.  If this is not done, the Inverter will shut
off automatically at around 10 V.

2.

If you are unsure if the inverter will have the proper amount of current to run the

device, use this rough guideline:  Take the power consumption of the load in
watts and divide it by 12 (input voltage).  The result will be the approximate
number of amps needed to power your device.

Example:  Load is rated at 312 watts.  312 watts / 12 V = 26 amps needed.  You

could use this device with the inverter.

3.

If your television will not start, it is important to keep in mind that some appli-

ances (including many televisions) may require two to six times their wattage to
start up.

4.

If your audio system buzzes while using this inverter, it is because some sound

systems can not filter out the modified sine wave produced by the inverter.  Use
a sound system that incorporates a higher quality power supply.

5.

This inverter is made to minimize the interference with TV signals.  However,

especially with weak TV signals, some interference may still be visible.  To
correct this, place the inverter as far away as possible from the television an-
tenna and it’s cables.  Next, adjust the orientation of the inverter to the antenna
cables and TV power cord to minimize the interference.  Also, use a shielded
antenna cable.

6.

If the low battery alarm is on all the time, try these corrective measures:  Re-

charge battery if in poor condition.  Next, check the battery connection.  You
may need to clean the connectors.

7.

If you are getting a low output voltage, try reducing the load to minimize watts.

You may have overloaded the inverter.  Reduce your load to 950 watts.  Also,
keep input voltage above 10.5 volts to maintain a constant flow of power.

8.

If you are not getting any power output, turn the power switch Off and On again,

until the green power light comes on.  Your devices may draw too much power to
operate them.   The inverter may be in thermal shutdown.  Let it cool down and
make sure there is adequate ventilation around the unit.
