Release 01/00
Procedure, TP37:
The default setting is signal tone ON. Touch the button shown here
in the System Settings standard screen to switch off the signal tone.
Toggle between signal tone ON and OFF by repeatedly touching the
button.
The volume can also be adjusted by means of the potentiometer on
the underside of the housing (see section 13.2).
Note
The signal tone is independent of communication with the PLC. It does not
indicate that the required action has actually been executed.
The TP27 has two buttons with which to adjust the contrast of the screen dis-
play in Online mode.
Increase contrast :
Touch the button depicted on the right on the System Settings stan-
dard screen. Each time the button is pressed, the contrast is in-
creased by one level.
Reduce contrast :
Touch the button depicted on the right on the System Settings stan-
dard screen. Each time the button is pressed, the contrast is reduced
by one level.
Apat from using these two buttons, the contrast can also be adjusted via the
Boot window (refer to chapter 13.2).
