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.

If adding a new piece of hardware to your recorder please be aware that if you are running Trend Manager PC software
that the “Hardware Wizard” will require updating to accommodate the hardware changes.

Panel Mounting

The Alarm/Digital IO cards can be removed, replaced or added to the recorder without removing it from its mounting
panel. If you require the recorder to 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.

Removing the Rear Panel

Removal of the rear panel is necessary for replacement or fitting any of the PC cards.
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.
