"BOOST" OPERATION:
1. Connect the Jump Starter to the vehicle battery (Red LED
keeps on and green LED is off), press and hold BOOST button
for 3 seconds (after a buzzer sound, the green LED is on and
red LED is off). "BOOST" is used when the vehicle battery
capacity is low.
2. Start the engine (same method as the normal operations on
Page 9).
Cautions:
1. Under normal circumstances, do not use BOOST. Use only
when the vehicle battery capacity is low.
2. The spark proof, reverse polarity protection and short circuit
protection features are disabled after BOOST button is
pressed. Pay very close attention to the polarity of the battery
before using this mode. Do not allow the positive and negative
battery clamps to touch or connect to each other as the item
will generate sparks and high heat if not used properly.
