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. 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 GBX45 to rest for fifteen (15) minutes before attempting to jump start the vehicle again.
4. Once you have started your vehicle, power off the unit, disconnect the battery clamps, and remove the GBX45.
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 GBX45 is designed to jump start 12-volt lead-acid batteries down to 3-volts. If your battery is below 3-volts, the Boost LED will be «off». This is an indication
that the GBX45 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 LEAD-ACID BATTERIES ONLY. 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 1250 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.
