Continual improvement policy
Arcam has a policy of continual improvement for its products.
This means that designs and specifi cations are subject to
change without notice.
Radio interference
The CD72 and CD92 players are digital audio devices which
have been designed to very high standards of electromagnetic
compatibility.
Both CD players and DACs generate, and can radiate RF (radio
frequency) energy. In some cases this can cause interference
with FM and AM radio reception. If this is the case, keep the CD
player and its connecting cables as far from the tuner and its
aerials as possible. Connecting the CD player and the tuner to
different mains sockets can also help to reduce interference.
EC COUNTRIES -– These products have been designed to
comply with directive 89/336/EEC.
USA – These products comply with FCC requirements.
Laser radiation
If an Arcam CD player is operated whilst the outer casing is
removed, invisible laser radiation could cause eye damage.
