11.6 Glossary of terms,
acronyms, abbreviations,
etc. used in this manual
The explanations given in table 1-3 are based on
the specific use of each term in this manual. The
definitions are not intended to be exhaustive. Many
of the terms have wider meanings!
11.2 Maintenance
During normal operation your PLM will provide
trouble-free service. The main user maintenance is
to periodically clean the dust filters behind the front
grilles. The two grilles can be removed by undoing the
knurled-head screws, and the foam filter elements
then withdrawn. They are best cleaned with a hand-
held vacuum cleaner.
If the LCD display needs cleaning, use a soft cloth
only – do NOT use solvent cleaners of any kind as
they may attack the plastic.
In some extreme cases it may be necessary to clean
the inside of the PLM. This procedure should only
be carried out by qualified service personnel. This
may be necessary if the PLM has had prolonged
operation in an extreme environment such as one
where “cracked oil” smoke machines are in use.
If you are using your PLM in such a heavy duty
application, it is recommended to have it serviced
every 3 years as a purely preventative measure.

11.4 Current draw and thermal
dissipation specifications
Table 11-2 contains data on measured current
consumption and calculated heat dissipation for
four operating conditions: i) Power on, no signal; ii)
Normal operation (1/8 of rated power); iii) Heavy duty
operation (1/4 rated power – see Note 3 at foot of
table); iv) 20 kHz sine wave
