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.
