2. Error LED
Illuminates Red if reverse polarity is detected, or blinks “On” and “Off” when the internal battery temperature is too high.
3. Power Button

4. Power LED
Illuminates White when unit is "On".
5. Light Mode Button
Toggles the ultra-bright LED light through 7 light modes: 100% > 50% > 10% > SOS > Blink > Strobe > Off
6. Voltmeter
The built-in voltmeter reads the voltage of the vehicle’s battery for enhanced diagnostics and troubleshooting. The voltmeter will automatically read the voltage of any battery (or battery system) when the battery clamps are connected, even if the unit is powered off. The voltmeter will read voltage between ~3V and ~20V. If the connected battery is below 3V, nothing will display. If the voltage is that low, there is likely a load(s) on the battery, such as headlights or and AC fan, that should be shut off before attempting to start the vehicle.
7. Boost LED
Illuminates White when Boost is active. If the unit is connected properly to a battery, the GB150 will automatically detect a battery and go into Boost mode (LED flashes White when Manual Override feature is active).
8. Manual Override Button
To enable, push and hold for three (3) seconds. WARNING: Disables safety protection and manually forces Boost "On". Only for use when a battery is too low to be detected.Learn More.
