1.4.1.3 Activation of the radio interface
The radio interface leaves the factory deactivated. It can be activated as follows:
a) The radio function can be activated by pressing the push-button.
Press the push-button until you change to the display loop "6" (module loop). Then change with a brief keystroke to the 2nd
item "rad(io) off" (see picture).
In order to start the editing mode you afterwards must press the push-button
once again for 2-3 seconds. As an aid, after 2 seconds the "editing pen" will be displayed
bottom left in the LCD. As soon as it appears you have to let go of
the button. Now the display shows "rad(io) on" and in all display loops a black triangle (see
picture).
b) The radio function can also be activated using the software "Device Monitor".
This software can be ordered separately as an option.
