If you set this switch to AUTO, the DAYNIGHT function will be automatically activated according to the illumination.

Upon saving, the DAYNIGHT mode will be automatically converted depending on DURATION TIME even in the event of POWER On/Off.

For resetting, please repeat the above procedure. (Upon resetting, you may r eturn both L/L and AWB to the previous condition.)
