d) Inserting the batteries
• FS20 SN requires two AAA batteries for operation.
• Remove the housing cover by loosening the four housing screws at the top. The rubber seal
might cause the cover to be slightly jammed. Carefully lever apart the two housing parts
using a flat-bladed screw driver (do not use force!).
• Carefully remove the electronic unit from the housing.
• Insert two batteries into the two battery holders with the polarity aligned (positive/+ and
negative/- is indicated on the board), see illustration above.
• Leave the housing open for further configuration. Make settings and programming changes.
Then close it again.
