DEES DSI-375, User Manual

Page: 11 / 48

The programming mode of the DSI is accessed directly after power is
applied to the unit and is identified by the rapidly flashing LED. You have
20 seconds to commence programming before the DSI times out. If you
wait longer than 20 seconds to commence programming, simply unplug
the power supply and reapply power to start again.
Follow the detailed instructions for each configuration. If a mistake is
made in an individual configuration program, beginning of that
configuration sequence. Do not forget to reapply power to the DSI before
recommencing programming.
If you wish to deactivate a single configuration once it has been entered,
follow the configuration instructions as before, but do not press 1 to
activate the feature, instead press 0 to deactivate the feature.
If you are unsure which programs are resident in the DSI, follow the
instructions outlined in Configuration 0, which will erase any programs
and return the DSI to its factory default mode.
When in Day Service mode, the DSI will monitor as many as 10 line
appearances and in Night Service mode the DSI will monitor all line
appearances including those on a multi-button add-on module.
