IMPORTANT!
When the programming work is done the unit
goes off-line, which means that the annunciator
unit is set out off its normal operation during the
time it is being programmed. The procedure
when it goes back from programming mode is
the same as when it starts up.

IMPORTANT!
The plug selector which is used to enable or
prohibit programming of the annunciator unit
can be located in two places named S1 and S2.
Programming is prohibited when the selector
plug is located in position S2 and enabled when
the selector plug is in the position S1. The front
panel can be dismounted by the four finger
screws on the front panel.
