IBM 3270 Operator's Guide

Click ( c1J ) Key
The Click ( r3J) key enables you to turn the keyboard clicking sound on or
off for normal operation. Pressing the Click key when the keyboard clicker
is working causes the clicker to stop. Pressing the Click key a second time
causes the clicker
to operate.
It is important to know that generally:
(t When you have the clicker turned on, the click tells you the keyboard is
operational and the data you are keying is being accepted. In this case,
absence
of the click indicates the keyboard is disabled.
(t When you have the clicker turned off, the absence of the click tells you
the keyboard is operational and the data you are keying is being accepted.
In this case, the presence of the click indicates the keyboard is disabled.
Therefore,
by being aware of the clicking, or of its absence, you can tell when
the
operation of your keyboard is not normal.

station to run tests that reside in the control unit. When the TEST key is
