Care and Maintenance
The HALCRO™ dm8 preamplifier has been designed for indoor use only. Under no
circumstances should the preamplifier be allowed to get wet. The only maintenance required is
to keep the unit clean.
Important.
HALCRO™ takes no responsibility for any damage caused through careless or improper
cleaning techniques. Never use flammable or corrosive products when cleaning the dm8.
Please read the following procedures very carefully.
The outer surface of the unit is anodized aluminum which, while being very durable, will be
marked if rubbed with an abrasive cloth.
Prior to cleaning, turn the power to the unit off at the mains.
Use only extremely soft cloths.
Use a soft dry cloth to remove any dust.
Add 15 milliliters (.5 Oz) of very mild household dishwashing detergent to a 4-litre (1 gal.)
bucket of lukewarm water. Immerse the soft cloth in the bucket of water, then wring the cloth
out thoroughly until the cloth is nearly dry.
The slightly damp cloth should only ever be used to clean the anodized aluminum surfaces.
Never clean any electrical fittings, terminals or the front and rear Labels with the damp cloth.
The labels can be cleaned using an extremely soft polishing cloth, which must be dry. No
moisture should ever be allowed to enter the units’ compartments through the joins in the
panels.
After using the slightly damp cloth, wipe over the surfaces with a soft dry cloth, then allow the
dm8 to air for at least one hour prior to turning the power back on.
If you are unsure about cleaning the preamplifier and require more information, please ask
