Operation Manual

51
Clean devices using a damp cloth. Never use
household cleaning products (washing powder, soap,
etc.) or alcohol to clean them. Never use a
microwave or other heating devices to dry any of
the devices.
The digitally coded, inductive transmission
technology used in these devices is extremely reliable
and experiences virtually no interference from
other devices. It should be noted, however, that when
operating the system near computer equipment,
larger electronic installations or other strong electro-
magnetic fields, it may be necessary to be at least
60 cm (24") away from the interfering device to
ensure proper operation.
