SAFETY TESTS
Upon completion of service procedures detailed in this manual two basic safety tests should be performed in order to
ensure continued safe operation of the instrument.
Earth Resistance; 25 VDC applied between case and protective earth, bonding resistance should be < 0.1 Ohm.
Insulation Resistance; 500Vdc applied between the earth terminal, and the live and neutral terminal shorted together,
insulation resistance to be >2.0 MOhm. (Mega Ohm, NOT milli Ohm)
Failure to comply with these instructions could result in death or serious injury
CAUTION
OBSERVE ANTI-STATIC PRECAUTIONS
Refer to BS EN61340-5-1: 2001. Basic specification. Protection of electrostatic sensitive devices.
Full anti-static precautions MUST be observed when in contact with the electronics of your recorder.

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.
SX 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 1 below
Slide the case and rear panel assembly off the recorder.

Next disconnect the inverter high voltage cables by pulling upwards. See Fig 5.
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. The screws are located one in each corner and one in the centre of each side. See
Fig 6.

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. Fig 7
To remove the display unscrew the four display fixing screws. As the display comes away feed the inverter cable
through the hole in the metal mounting plate, and disconnect the display cable by gently pulling on the connector
housing.
Once disconnected the display should be free. Put the cable face down ensuring it is on a surface that will not scratch it.
Avoid getting dirt or finger marks on the display.

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.
Use a lint free cloth to clean both parts, do not use any solvents.
Refit the 8 screws that hold the front bezel in place.
Plug the inverter lead back into the inverter.
Slide the case back onto the recorder ensuring it is fitted the right way round. The cooling slots should be at the top of
the unit.
Finally fit the four M4 screws that hold the case to the chassis.

Take the display assembly and place it back into the bezel/touch screen assembly. Fit the 4 self tap screws that attach
the two parts.
Offer up the front surround to the unit, reconnect the display lead, pulling up the top of the connector to allow the lead to
be seated, and then push the top down to clamp the lead in place. Re-connect the inverter lead, touch screen lead and
speaker lead.
Slide the front surround assembly onto the chassis plates and fit the 4 self tap screws that hold the unit together.
Slide the case back onto the recorder ensuring it is fitted the right way round. The cooling slots should be at the top of
the unit.
Finally fit the four M3 screws that hold the case to the chassis.
