Step 3: Jump Starting.
1.) Make sure all of the vehicle's power loads (headlights, radio, air conditioning, etc.) are turned off before attempting to jump start the
vehicle.
2.) Press the power button to begin jump starting, and all LEDs will flash once. If you are properly connected to the battery, the white
boost LED will illuminate and the battery charge LEDs will chase. A 60-second timeout countdown will begin as soon as a battery is
detected.
3.) Try starting the vehicle. Most vehicles will immediately start. Some vehicles may require the GB251 to be connected for up to 30
seconds before starting. If the vehicle does not start right away, wait 20-30 seconds and try again. Do not attempt more than five (5)
consecutive jump starts within a fifteen (15) minute period. Allow the GB251 to rest for fifteen (15) minutes before attempting to jump
start the vehicle again.
4.) Once you have started your vehicle, disconnect the battery clamps, and remove the GB251.
60-Second Timeout.
A 60-second countdown will be initiated as soon as a battery is detected. After 60 seconds has elapsed, the jump starting function will
be disabled. The boost LED will turn off and the internal battery charge LEDs will indicate the current charge level of the unit. To reset the
jump-starting function, press the power button to power off the unit. Press the power button again to power on the unit and restart the
jump starting function.
CAUTION.
60-SECOND TIMEOUT IS DISABLED WHILE USING MANUAL OVERRIDE MODE. POWER WILL CONTINUE TO BE SUPPLIED WHILE
MANUAL OVERRIDE IS ACTIVE. TO MAXIMIZE THE NUMBER OF JUMP-STARTS, IT IS RECOMMENDED TO TURN OFF THE BOOST-UNIT AS
SOON AS THE VEHICLE HAS STARTED.
