3.5 Local Functions of the OP Service Menu
For simple hardware check of the OP and for certain system parameters
there is a local Service menu in the operator panel. The OP functions are
quite independent of the other TAC Xenta units and only require that the
operator panel is connected to the network and that the panel has not
been set in the TAC Xenta 100 communication mode (see below).
The Service menu appears if both the keys and are pressed
for about three seconds simultaneously .
