(‘Operator mode’)

This chapter provides basic information on how to digitize 
image plates under normal conditions and in emergency 
situations. It also treats how to erase an image plate to 
prevent ghost images caused by previous exposures or by 
scattered radiation. These functions are available in 
operator mode.
