NOTE: This converter has a cooling fan that runs continuously. Do NOT
leave it plugged into the vehicle when the engine is not running, or it will
drain the battery.
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.

5. POWER SOURCE

To get the best performance out of your converter, we recommend that you
use it with the vehicle's engine running.
Your average automobile or marine battery at full charge will provide an ample
power supply to the converter for approximately 3 hours when the engine is off.
The actual length of time the converter will function depends on the age and
condition of the battery and the power demand being placed by the device being
operated with the converter.
