Page 2: Panel Mounting
Before attempting to repair or upgrade a recorder, it is advisable to clear a sufficient work space so components such as the front panel can be rested on the work surface without getting scratched or damaged. Panel Mounting Before a new backlight can be fitted the recorder must be removed from the panel. Loosen the mounting clamp screws, slide the clamp towards the rear of the recorder and remove the clamps and the recorder. - Page 3 Next disconnect the inverter high voltage cables by pulling upwards. See Fig 5. Fig 5 Inverter cable Remove the eight self tapping screws that fix the plastic bezel to the mounting plate. A screw driver with a long shaft will make this operation much easier.
- Page 4 Once the screws are removed the black plastic bezel and touch screen assembly can be folded down. The touch screen will still be connected so take care not to damage this lead.

- Page 5 Where the inverter lead comes out of the display there is a clip that will release the backlight. See Fig 9. Fig 9 Clip Press the clip down and gently pull on the cable to withdraw the backlight assembly. See Fig 10 Fig 10 Once the backlight has been removed the new backlight assembly can be fitted.
- Page 6 Re-building the recorder Rebuilding the recorder is the reverse process. Offer up the display to the front of the unit, reconnect the display lead and feed the inverter cable through the rectangular hole in the mounting plate. Fit the 4 screws holding the display in place. Before refitting the bezel/touch screen assembly clean any dirt or marks form the back of the touch screen or display.
- Page 7 QX Recorder To fit a new backlight the case and back panel must be removed. The case and back panel can be removed as a single assembly. Remove the 2 screws on each side of the case as shown in Fig 11 below Fig 11 Remove 2 screws from each side of the case...
- Page 8 To remove the Front surround assembly four self tapping screws must be removed. See Fig 13 Once these have been removed the front surround assembly can be carefully drawn forward. Disconnect the speaker cable from the mother board. Disconnect the display cable, inverter cable and touch screen cable from the processor board.
- Page 9 To remove the front bezel and touch screen assembly there are 4 self tapping screws that need to be removed, see Fig 14. Two screws are at the top of the assembly, and two screws are fitted one from each side. When these are removed the display assembly can be separated.
- Page 10 There are 2 backlights on the QX recorder display. These should be changed as a pair. To get the backlights out use a small screwdriver to push back the clip as shown in Fig 16 and gently pull on the leads to withdraw the backlight from the display.
- Page 11 Re-building the recorder Rebuilding the recorder is the reverse process. Feed the backlight leads through the holes in the moulding, and re-connect to the inverter.
