Device Address
The dim and reference level LEDs will
display the Model 71’s device address.
The rotary level control is used to select
the desired device address; the LEDs will
respond accordingly. The device address
must be selected so as not to conflict with
the device address of any other connected
Model 71 or Model 790 Control Console.
The choices are A1, A2, A3, and A4. All
Model 71 units have a default device
address of A4; Model 790’s units have a
default device address of A1. This ensures
that, in most cases, no change will have to
be made. Refer to Figure 9 for details.
Button Disable
To disable the Model 71’s two buttons,
simultaneously press and hold both the
dim and reference buttons for two sec-
onds. When the disable request has been
recognized the LEDs above both buttons
will flash rapidly. Release the buttons and
they will no longer enable or disable their
normal functions. To return the buttons to
normal operation simultaneously press and
hold both buttons for two seconds at which
time the two LEDs will flash rapidly.
To leave the configuration mode and return
a Model 71 to normal operation requires
one last action: again press and hold its
configuration button for two seconds. The
selected configuration parameters will be
stored in a nonvolatile memory device that
is located inside this specific Model 71.
