IMPORTANT: This inverter uses a modified sine waveform (diagram A) which is

not quite the same as power company electricity (diagram B). For the following

devices, we strongly recommend that you use caution and check the device’s

manual to make sure it is compatible with modified sine waveform.

1. Switch mode power supplies

2. Linear power supplies

3. Class 2 transformers

4. Line filter capacitors

5. Shaded pole motors

6. Fan motors

7. Microwave ovens

8. Fluorescent and high intensity lamps (with a ballast)

9. Battery chargers without transformers

Using the inverter with any of these devices may cause the device to run

warmer or overheat.

IMPORTANT: If you are using the power inverter to operate a battery

charger, monitor the temperature of the battery charger for about 10

minutes. If the battery charger becomes abnormally warm, disconnect it

from the inverter immediately.
NOTE: You may hear a “buzzing” sound being emitted from inexpensive

sound systems when operated with the inverter. This is due to ineffective filters

in the sound system’s power supply. Unfortunately, this problem can only be

resolved by purchasing a sound system with a higher quality power supply or

higher quality filter.
