9b. P RESS RESERVE POWER – the disabled vehicle's state of charge is not high
enough to use to charge the ultracapcitor. Press RESERVE POWER and the
unit will count up as the ultracapacitor is charged to full from the internal lithium
battery and the Green READY LED is lit. The unit will sound an audible beep
indicating it is ready to jump start. The jump starter function is engaged for 30
seconds, after which the unit will return to idle mode.
9c. No lights lit / no vehicle voltage shown – the disabled vehicle's battery is so
discharged that the jump starter cannot recognize it and sense the vehicle's
polarity (<1.5VDC). Check all connections and ensure proper polarity of your unit
to vehicle cable/clamp connects. Press JUMP START to activate the unit. Press
RESERVE POWER to charge the ultracapacitor. After ultracapacitor reaches
100%, press and hold the JUMP START button for 3 seconds. Green ready
LED will flash for 10 seconds. The jump starter function will then engage for 30
seconds, after which the unit will return to idle mode.

Performance of your Jump-N-Carry will depend upon several factors:
• A good, solid connection between the Jump-N-Carry clamps and the battery
and ground connections are a must. Moving the clamps back and forth while
connecting to the battery will help create a better connection.
• Clean connections between your vehicle or equipment battery and its terminals
are very important. For an optimal connection, corrosion (soft grayish-white build-
up) on battery terminals must be removed. With the ignition turned off, disconnect
the battery cables and clean the terminals and battery posts with a baking soda
solution.
