Maintenance
This device does not contain any replaceable parts. If it needs service take it to a
qualified technician.
Troubleshooting Tips
1. If the low battery alarm sounds, this means that the input voltage is below the
necessary 10.7 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 10.0 V.
2. The Inverter will automatically shut down if the input voltage exceeds 15 volts
DC.
3. The Inverter will shut down when the internal temperature reaches unsafe
levels. You may restart the inverter by turning the rocker switch to Off, waiting
15 minutes, and then pushing the rocker switch back to On.
4. 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 number of
amps needed to power your device.
Example: Load is rated at 320 watts. 320 watts / 12 V = 26 amps needed.
You could use this device with the inverter.
5. If your television will not start it is important to keep in mind that some
appliances may require two to six times their wattage to start up. This
inverter will not work with such devices.
6. Your power tools start up but don’t continue to run: Try leaving the power to
the tool on, while quickly but repeatedly turning the inverter power switch On
and Off.
7. 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. The only solution is to use a sound system that incorporates a
higher quality power supply.
8. 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
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.
