IMPORTANT: This converter 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 converter with any of these devices may cause the device to run
warmer or overheat.

IMPORTANT: If you are using the power converter 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 converter immediately.
NOTE: You may hear a "buzzing" sound being emitted from inexpensive
sound systems when operated with the converter. 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.
