S Screen Saver Function Releasing Attribute
With this attribute set to an input terminal, an OFF state is released when the
input terminal turns ON, even if the backlight is turned OFF with the screen sav-
er function activated (see page 95).
However, for the terminals to which both numeric key and screen switchover
functions are assigned, the screen saver function is always released. For the
terminals to which the input notifying function is assigned and the terminals to
which any function is not assigned, screen saver attribute and not-release at-
tribute can be selected.
For example, with the screen saver attribute set to the terminals without this
function, the PT screen can be displayed when a person approaches to the
NT30/30C, by combining with a sensor as shown below.

When turning ON the terminal to which both screen switchover key and numeric
key functions are assigned, with the screen saver, only the screen saver state is
released and the function of those keys will not be implemented. However, in
case of input notifying key, it is notified to the PC irrespective of the screen saver
release attribute.
S Key Press Sound
Though a key press sound does not sound under any circumstances for the
input notifying key, sound or no sound can be selected for other function and
non-function keys according to the memory switch setting (see page 92).
