OPO sprl, Crawhez 9, 4890 Thimister Clermont, Belgium. +32 87688989 - +32 87598990 Problem Most probable Cause Solution / notes 1 JOYSTICK: Cannot obtain ENTER pressing the joystick Joystick needs to be precisely positioned while pressing Enter. Training. After short training joystick operations seems to be easier. Note. The software behind the joystick interprets double action (like enter and right) as Enter. However the enter contact may be reached only in very strict direction.

The new mechanical design will solve this problem. 2 POWER: CT7 does not power – up Battery discharged Press RESET button, connect to USB power, try again after 15 minutes of charge (still connected to USB) 3 POWER: CT7 switch off during operation Battery discharged Charge the battery with USB, try to see Status voltage V3.
