Power Source; Led Indicator And Shutdown Protection - DieHard 28.71522 Manual Del Usuario

IMPORTANT: If you are using the power inverter 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 inverter immediately.
5. OPERATING INSTRUCTIONS
1. If connecting in a vehicle, remove the cigarette lighter from its outlet.
2. Push the 12 volt power plug firmly into the outlet.
3. The LED indicator light should glow GREEN, verifying the inverter is receiving power.
4. Make sure the device to be operated is turned OFF.
5. Plug the device into the inverter AC outlet or USB port.
6. Turn the device on.
7. To disconnect, reverse the above procedure.
NOTE: You may hear a "buzzing" sound being emitted from inexpensive sound
systems when operated with the inverter. 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.

6. POWER SOURCE

Your average automobile or marine battery at full charge will provide an ample
power supply to the inverter for approximately 3 hours when the engine is off. The
actual length of time the inverter will function depends on the age and condition of
the battery and the power demand being placed by the device being operated with
the inverter.
Before starting the engine after using the inverter with the engine off, turn OFF the
device plugged into the inverter and disconnect the inverter plug from the 12 volt
accessory outlet. To maintain battery power, start the engine every 2 to 3 hours
and let it run for approximately 10 minutes to recharge the battery.
Although it is not necessary to disconnect the inverter when turning over the
engine, it may briefly cease to operate as the battery voltage decreases. While the
inverter draws very low amperage when not in use, unplug it to avoid battery drain.

7. LED INDICATOR AND SHUTDOWN PROTECTION

The LED glows GREEN automatically when plugged into a 12 volt DC source and
will not glow under the following conditions:
1. When the power input from the vehicle's battery drops to approximately
10.5 volts, low battery shutdown occurs and inverter shuts off.
Solution: recharge or replace the battery.
