3.As the battery charge is used up, battery voltage begins to fall. When the Jazz 300 senses that the voltage at its DC input has dropped to 10.7 volts, an audible alarm sounds. This allows time for computers or other sensitive devices to be shut down.
4.If the audible alarm is ignored, the Jazz 300 will automatically shut down when the battery voltage drops to 10.0 volts. This prevents battery damage from excessive discharge. After auto shut down, the red FAULT light illuminates.
IMPORTANT: Vehicle batteries are designed to provide brief periods 
of very high current needed for engine starting. They are not intended for constant deep discharge. Regularly operating the Jazz 300 from a vehicle battery until the low voltage alarm sounds will shorten the life of the battery. Consider connecting the Jazz 300 to a separate deep discharge type battery if you will be frequently running electrical products for extended periods of time.
5.If an AC product rated higher than 240 watts (or which draws excessive surge power) is connected, the Jazz 300 will shut down. The red FAULT light will turn on.
