Evoke Mio\ 1S blank display
On very rare occasions you may experience the display on an Evoke Mio or Evoke 1S appearing blank or' black' with no visible text. If this happens to your radio, you should try removing all power sources from the product - including any installed ChargePAK battery packs. Reapply power as normal and the screen and text should reappear as normal.
If this doesn't solve the problem then contact the Pure support team for further advice.
