MAINTENANCE
On a regular basis, the inside of the PE3M unit should be cleaned out to prevent dust build up which could
eventually clog the fans and prevent efficient operation. Generally the enclosure design and the wiring layout will
ensure that the coolign is stable. However, bear in mind that any modifications to the installation may cause a restriction
of the air vents. After a period of several years, it may be necessary to replace the battery on
the processor board, if it cannot maintain the CMOS memory.
Replacing the Processor Battery
The processor board includes a small 3V lithium battery (type CR-2032) to retain the BIOS settings in the
CMOS memory. Before attempting to replace the battery, please read the precautions detailed in the
introductory section. Remember that even discharged batteries can present a real personnel hazard if
mistreated.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to the manufacturer's instruction.
ATTENTION
Il y a danger d'explosion s'il y a remplacement incorrect de la batterie.
Remplacer uniquement avec une batterie du même type ou d'un type
recommandé par le constructeur.

The battery is held in place by the clip in the top of the plastic carrier. To remove the battery, press the
retaining clip with a flat-headed screwdriver to force it away from the battery, then lift the battery clear of
the holder.
Replace the battery ensuring that it is fitted with the positive face up (visible), and that the clip is fully
engaged. When the battery has been replaced, the BIOS settings will revert to their default settings. Reset
them as necessary to suit your application.
