ON/OFF buttons
The ON/OFF buttons are used to activate and deactivate the device. When the plotter
is switched on, the writing arm moves to the top right-hand corner of the labelling area
and auto calibration takes place. The green light comes on when the system is ready
for use and to receive data from the PC.
Clear buffer
If the EMS-3 contains data the yellow light will come on. You can delete this data by
pressing the Clear buffer key.
To do this the system must be in stop mode (red light on).
