You can move the keypad to any place on the display. Touch the upper left-hand corner of the keypad and drag it to the place where you want it.

The Terminal menu cannot be accessed while-the keypad is displayed.

In addition, you can set the unit’s display to FIXED or VIRTUAL using the menu. The unit’s display is smaller than that of standard personal computers. When VIRTUAL is selected, text transferred from personal computers will be received in the same format as for a conventional remote terminal, and the unit’s display will form a window on the text. Use the cursor keys to view text that is off the display. In the default setting, pressing m + cursor key will move the display window 40 characters horizontally or 8 lines vertically.

If FIXED is selected, text that cannot fit on one line is moved to a new line.
