Graphical User Interface (Gui) - Spectrum DSP M2 User Manual

Graphical user-interface (GUI):
Note: All references to TX operation are included for the future inclusion of a TXRX module which
converts the Spectrum into a DSP transceiver.
The touch screen is easily controlled once the basic technique is mastered.
Clicks with the stylus should be made in a deliberate manner, approximately half a second
long will activate the menu and control buttons, any longer and they will be detected as a
long-press, which activates secondary functions which most buttons and touch areas posses.
You can practice this by clicking on the
the menu list, a long-press will mute the audio, making another long-press will reactivate the
audio. If the volume is too low, click DSP/OFF and stroke up on the left-side.
A video on YouTube is available showing how to use the touch interface, available here,

as follows:
