3.1.1 Switching on / off

) or directly after switching on, the display reads:
battery symbols
The battery symbols show the charge level of the battery; in this case, full capacity. The
bar indicates the progress of the inspection and stabilization phase. Furthermore, the soft-
ware version of the device, a selected tester, date and time are shown.
The system check takes 5 seconds.
If errors are detected, warning messages are shown; otherwise the “selection of functions”
menu is opened.
Switching off:
press “F” key for a longer period (> 3 sec.) or using the “switch off” function
in the “selection of functions” menu.
3.1.2 Functions of the function keys
The assignment of the functions keys is shown in the last line on the display re-
spectively.
The P7-TDX has a touch screen. Touching the display in the relevant spot replaces the
command executed with the key. You can scroll the displayed content by dragging your
finger in a specific direction on the screen. When entering numeric values (e.g. test pres-
sure), the numeric value can be changed by dragging across the screen diagonally.
If the middle screen key is occupied by two functions, e.g. (▲▼), one of the functions is
located on the right side of the key displayed and the other function on the left side.
