Hummer H3 User Manual page 9

FAQ:
Q1: What are the features of the H3?
A1: Apart from jump starter function, the H3 can be used to recharge virtually any 5V
powered USB devices, such as mobile smartphones, tablets, portable gaming system,
digital cameras, camcorders, and portable GPS devices, etc. It can also jump start a
drained car battery with the included Sparkless Smart Cable. It is also equipped with a
built-in ultrabright LED flashlight.
Q2: How does the Sparkless Smart Cable work?
A2: If the green indicator light is on, means ready to jump start; If the red indicator light
is on, means a misconnection between the clamp and the battery terminal; 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. If the red indicator light is blinking, means
the Reverse Charge protection is activated or Low Battery.
Q3: Will reversing polarity connections of the jump start cable damage the vehicle?
A3: Not at all, the H3 is very safe with Sparkless Smart Cable. If you accidentally connect
the RED and BLACK cable clamps to the wrong polarity terminal and attempt to jump
start the vehicle, the Sparkless Smart Cable (the red indicator light is on) will cut the
power immediately to prevent injury and avoiddamaging the vehicle.
Q4: What if it doesn't jump start the vehicle?
A4: If the H3 fails to jump start the engine, please wait at least 10 seconds before
attempting to try again and please do not crank the engine continuously for more than 5
seconds each time. If still not succeed after 3 attempts, it may be due to other
problems of the vehicle. Do not try to crank the engine continuously for more than 10
times in a row. It is also highly recommended to replace the vehicle battery once every
2-3 years.
