TROUBLESHOOTING TIPS
If the alarm sounds, this means that the input voltage is at or below 11 V. The bat-1.
tery needs recharging. You should stop using the Power Inverter and recharge the
battery. If this is not done, the Inverter will shut off automatically at 10.5V.
If you are unsure if the inverter will have the proper amount of current to run your 2.
devices, add up the total of the continuous wattage for the items. If this gure is
under 200 then the Inverter will be able to run the items at the same time.
If your television will not start, it is important to keep in mind that some appliances 3.
(including many televisions) may require two to six times their wattage to start up.
If your audio system buzzes while using this inverter, it is because some sound 4.
systems can not lter out the modied sine wave produced by the inverter. Use a
sound system that incorporates a higher quality power supply.
This inverter is made to minimize the interference with TV signals. However, 5.
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 antenna 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.
If the low battery alarm is on all the time, try these corrective measures: Recharge 6.
battery if in poor condition. Next, check the battery connections. You may need to
clean the connectors.
If you are getting a low output voltage, try reducing the load to minimize watts. You 7.
may have overloaded the inverter. Reduce the number of watts you are powering.
Also, keep input voltage above 11 volts to maintain a constant ow of power.
If you are not getting any power output, turn the power switch Off and On again, 8.
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.
