Troubleshooting Tips - CEN-TECH 66817 Owner's Manual & Safety Instructions

troubleshooting tips

• If the alarm sounds, this means that the input voltage is at or below 10.9 V. The
battery 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 10.5 V.
• If you are unsure if the inverter will have the proper amount of current to run your
devices, add up the total of the continuous wattage for the items. If this figure is
under 750 then the Inverter will be able to run the items at the same time.
• If your product, such as a television will not start, it is important to keep in mind that some
appliances (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 systems can not filter out the
modified 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, 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 battery if in
poor condition. Next, check the battery connection. You may need to clean the connectors.
• If you are getting a low output voltage, try reducing the load to minimize watts. You may
have overloaded the inverter. Reduce the number of watts you are powering. Also,
keep input voltage above 11 volts to maintain a constant flow of power.
• 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.
