HAZARDOUS VOLTAGES
Disconnect all power to the recorder before removing the case and attempting any maintenance procedures.
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.
SAVE DATA, SETUPS AND LAYOUTS
Removal of PCBs and battery back-up will result in the loss of all non-volatile data.
Ensure all data and set-ups are saved.
Failure to comply with these instructions may result in product damage.

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
To remove the recorder from the panel, loosen the mounting clamp screws, slide the clamp towards the rear of the
recorder and remove the clamps and the recorder.
Removing the Rear Panel
To remove the rear panel of the recorder, loosen and remove the two screws (QX and Qxe = M3 x 6, SX = M4 x 8) at
the top corners of the rear panel, taking care to retain both the shake-proof washer and the screw.
To replace the back panel remove any blanking plates from the old back panel and re-fit in the same positions on the
new back panel.
Removing the Case
To remove the case there are 2 screws on each side of the recorder that must be removed.

Once the screws are out, the case can removed by sliding towards the rear of the recorder.

Refitting the case
To fit the case, carefully slide it on from the rear of the recorder. Ensure the case is orientated with the power supply
cooling slots on the top of the recorder.
Slide the case fully forward ensuring that no internal cables get trapped between the case and front bezel.
The case should sit flat on the back of the front bezel.
Re-fit the four screws that secure the case. (QX and QXe M3 x 6mm, SX M4 x 8mm)
Screw should be tightened to a torque of 120cNm.
Refitting the rear panel
To replace the rear panel, angle the rear panel as shown to line
up two location points with the floor of the recorder’s case.
Reposition the shake-proof washers and replace and tighten two
screws (QX and QXe = M3 x 6, SX = M4 x 8) at the top corners of
the rear panel.
If the recorder has been removed from the panel, refit the
mounting clamps to the case in two opposite positions and secure
into the panel.
QX and QXe torque setting should be 0.5 - 0.75Nm/4.4 - 6.6lbf-in
SX torque setting should be 0.5 - 0.70Nm/4.4 - 6.2lbf-in
