Using a keyboard
A standard AT keyboard can be connected
to the Servo Screen 390.
When the keyboard is connected, it is ready
for use. No setting is needed. The keyboard
can be used as a substitute for the control
knob/pulse generator, but it can also be used
in combination with the control knob/pulse
generator.
The following keys are used to simulate the
control knob:
• Left-arrow key = Turning the control knob
counter-clockwise.
• Right-arrow key = Turning the control knob
clockwise.
• Enter key = Pressing the control knob.
The keyboard can be used when trouble-
shooting a possible malfunction in the
control knob function, for example. If there is
a malfunction when using the control knob/
pulse generator and this malfunction does
not appear when using a connected
keyboard, the error may be in the pulse
generator or in the pulse generator interface.
The keyboard can also be used in combi-
nation with the ”on-screen keyboard” when
entering or changing a patient ID. Only upper
case letters will be displayed in the Patient
ID field.
