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. If the vehicle
is equipped with a Master Switch, turn it to the "on" position.
2.) Verify the voltage of the vehicle's battery system, and turn the voltage selection knob to the correct voltage.
3.) Press the Power Button to begin jump starting. All LEDs will flash, indicating that all LEDs are properly functioning. If Boost is properly connected to the
battery, the White Boost LED will illuminate and the 25%-100% LEDs will chase. A 60-Second Timeout countdown will begin as soon as a battery is detected.
4.) Try starting the vehicle. Most vehicles will immediately start. If the vehicle does not start right away, wait 20-30 seconds and try again. After the 60-Second
Timeout is complete, the unit must be powered off, then back on, to initiate a new jump-start sequence. Do not attempt more than five (5) consecutive jump
starts within a fifteen (15) minute period. Allow the GB500 to rest for fifteen (15) minutes before attempting to jump start the vehicle again.
5.) Once you have started your vehicle, power off the unit, disconnect the battery clamps, and remove the GB500.
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.
Low Voltage Batteries & Manual Override.
The GB500 is designed to jump start batteries down to 3-volts. If your battery is below 3-volts, the Boost LED will be "Off". This is an indication that the GB500
can not detect a battery. If you need to jump start a battery below 3-volts there is a Manual Override feature, which allows you to force "On" the jump start
function.
CAUTION.
USE THIS MODE WITH EXTREME CARE. THIS MODE IS FOR 12-VOLT OR 24-VOLT LEAD-ACID BATTERIES ONLY. ENSURE THE VOLTAGE SELECTION KNOB
IS IN THE CORRECT POSITION (12V OR 24V) MATCHING THE BATTERY SYSTEM BEING JUMP STARTED. BOTH THE SPARK PROOF AND REVERSE POLARITY
PROTECTION FEATURES ARE DISABLED. 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 PRODUCT WILL GENERATE SPARKS. THIS MODE USES
VERY HIGH CURRENT (UP TO 6250 AMPS) THAT CAN CAUSE SPARKS AND HIGH HEAT IF NOT USED PROPERLY. IF YOU ARE UNSURE ABOUT USING THIS
MODE, DO NOT ATTEMPT AND SEEK PROFESSIONAL HELP.
