4.2 Write Enable/Inhibit Switch
The DAU is equipped with a switch that can be used to prevent
unauthorized changes in the database (EEPROM).
In order to enable programming of the EEPROM, the S1 switch must be
set in the position, towards the block terminals. The switch can be locked
and sealed in the write inhibit position using a wire through the clevis
pins.
