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.
