Setup Guide Indoor/outdoor: Dip switch 1, default setting is for "outdoor", no matter the sensor is placed indoor or outdoor, set this dip switch to outdoor to avoid system picks up noise and triggering false lightning. Antenna: Dip switch 2, default setting is for long antenna, as this is the antenna used inside.Please do not make any change with this dip switch setting. Sensitivity: Dip switch 3,4.
