USER INTERFACE |
3.1Preliminary notes
Operating statuses:
- “on” status (the device is powered and is on; utilities may be on
- stand-by” status (the device is powered but is switched off via software; utilities are off
- the “off” status: the device is not powered; utilities are off.
Hereafter, if the POF parameter is set to 0, with the word “switch-on” means the passage from “off” status to “on” status; the word “switch-off” means the passage from “on” status to “off” status.
If the POF parameter is set to 1, with the word “switch-on” means the passage from “stand-by” status to “on” status; the word “switch-off” means the passage from “on” status to “stand-by” status.
When the power is switched back on, the device displays the status that it was in at the time it was disconnected.
3.2Device switch-on/off
If the POF parameter is set to 0:
1.Connect/disconnect the device power supply. If the POF parameter is set to 1:
2.Make sure that the keyboard is not locked and that no procedure is in progress.
3.Hold the
