Operating Voltage and 12/24 Buttons
Operating Voltage Selection.
This tool can be used on vehicles with a 12V or 24V system, but it is essential to be
aware of the vehicle's voltage BEFORE operating the jumpstarter.
The starter has an automatic voltage recognition system that works according to this
logic:
1. Vehicle battery voltage < 9.0Volt – The 12Volt indicator light flashes - The system
indicates that the vehicle's operating voltage is 12Volt, but the battery is too low
to have starting consent. Press the 12Volt button three seconds to activate the
starter and start the vehicle in the next thirty seconds
2. Battery voltage between 9.10Volts and 15.0Volts - The 12Volt light is steady
green - The system indicates that the vehicle's operating voltage is 12Volt and
It's ready to start. WARNING: If you are certain that the vehicle has 24Volt voltage,
press the 24Volt button three seconds to change the voltage on the jumpstarter
and start the vehicle. WARNING: If this operation is carried out incorrectly
on a vehicle with a 12Volt system, serious damage to the vehicle's CPU
and probable hydrogen production from the batteries will occur: EXPLOSION
HAZARD
3. Battery voltage >15.0Volt - The 24Volt indicator light is steady green - The system
indicates that the vehicle's operating voltage is 24Volt, and it is ready to start.
Start the vehicle within 30 seconds.
On vehicles without a battery or with an extremely low battery, it is possible that no
voltage indicator light comes on. In this case the polarity sensor will not signal an
error, so proceed with extreme caution:
1. Make sure the connection polarities are correct.
2. Select the voltage manually by pressing the 12Volt or 24Volt button for three
seconds.
3. Proceed to start up and quickly disconnect the clamps from the battery.
