NOCO Genius Boost 3000 Amp UltraSafe Jump Starter & Power Pack - Manual (Page 6)

1.) Internal Battery Level Indicates the charge level of the internal battery.
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 Push to turn unit "On" & "Off".
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 >

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 Overide 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.
