Care and Maintenance
The dm78 and dm88 monoblock amplifiers
have been designed for indoor use only.
Under no circumstances should the amplifier
be allowed to get wet. The only maintenance
required is to ensure the unit is kept clean.
Cleaning
Halcro takes no responsibility for any damage
caused through careless or improper cleaning
techniques.
WARNING: Never use flammable
products when cleaning the
dm78 or dm88.
The outer surface of the unit is
anodized aluminum, which while
being very durable, will be
marked if rubbed with an
abrasive cloth.
Please read the following procedures very
carefully:
o
Before cleaning, turn the power to the
unit off at the mains.
Use only extremely soft cloths.
o
Use a soft dry cloth to remove any dust,
particularly from the heat-sink area.
o
Add 15 ml (0.5 oz) of very mild household
dishwashing detergent to a four-liter
(one-gallon) bucket of tepid water.
o
Immerse the soft cloth in the bucket of
water and then wring the cloth out
thoroughly until the cloth is nearly dry.
o
Use the slightly damp cloth
only
to clean
the anodized aluminum surfaces and
timber feet.
Never clean any electrical fittings,
terminals or the front and rear Labels with
the damp cloth.
No moisture should ever be allowed to
enter the amplifier's compartments
through the joins in the panels.
o
After using the slightly damp cloth, wipe
over the surfaces with a soft dry cloth.
o
Clean the labels using an extremely soft
polishing cloth, which must be dry.
o
Allow the amplifier to air for at least one
hour before turning the power back on.

amplifier and require more information, please
