For mobile applications or, like our Classic "Rick mode" when you want all of the lights off:
The "S" version (MNBCMS) of the meter has an additional short wire attached. This wire is the "Switched lead" This feature allows the LEDS to be turned off while retaining the Battery Care memories. This wire should be connected through a fused switch to Battery positive. This is usually the ignition switch of a vehicle, but can also be any type of push button, or toggle switch.
