Makita SKR300 Service Manual page 9

Auto : Automatic levelling.
Default mode when laser is switched on
Man : Manual use.
The SKR300 laser is always in the automatic self-levelling mode (auto) when
turned on. Once the instrument has self-leveled, the laser head will start
rotating.
You can choose to have constant rotation by using the Manual mode. This way, the
beam will rotate even if the instrument is not leveled. The red light above the
Auto / Manual button will blink to indicate the instrument is in manual mode.
