Sangean WFR-2D V.1 - Manual (Page 8)

Using the touch screen
The WFR-2D internet radio has a high resolution color display with touch sensitive controls.
When using the internet radio, the display shows only the controls that are needed at each stage
of its operation. To operate the controls simply touch the button area with the tip of a finger for
about half a second until the command has been accepted.
You may find that at first, the internet radio does not always detect that you have touched a
button. If so, try touching with a little more pressure, or for slightly longer. You will soon find the
optimum touch needed to control your internet radio.
The panel may be cleaned using a dry cloth. Do not use abrasives, cleaning fluids or solvents.
