Care & Maintenance
To remove dust from the cabinet of your Delta PRE, use a feather duster or
a lint-free soft cloth. To remove dirt and fingerprints, we recommend using a
microfibre cloth and an anti-static spray such as lens or display cleaner applied to
the cloth, not directly onto the Delta PRE.
Dampen the cloth with cleaner fluid first and then lightly clean the surface of
the Delta PRE with the cloth. Do not use excessive amounts of cleaner that
might drip off the cloth and into the Delta PRE.
Caution! Power down and remove the AC power cord from the
Delta PRE before performing maintenance. At no time should
liquid cleaners be applied directly to the unit, as direct
application of liquids may result in damage to electronic
components within the unit.
