TWO lights).

3. Connect Red clamp to the positive (+) battery terminal first, then connect Black
clamp to the negative (-) battery terminal.
4. Before jump starting, check the jump start indicator beside the BOOST button.
a. If the green indicator light is on, means ready to jump start.
b. If the red indicator light is on, means a misconnection between the clamp and battery
terminal.
c. If the red indicator light is blinking, means Reverse Charge protection is activated or
Low Battery.
d. If no light is on, press the BOOST button for 3 seconds until the green indicator light
turns on, by which time the jump starter is ready for use.
