Important information
All systems using radio and telecommunications are subject to interference beyond the user's
control.
Products from Doro are designed to minimize the impact of such interference. Nevertheless, the user
must be aware that system components can be subjected to interference or other influences that
may cause malfunction.
It is therefore important to regularly check that every part of the system works in all areas, especially
radio communications. Contact your supplier immediately in case of any suspected malfunction.
Keep the product away from interfering devices such as radio transmitters, mobile phones, DECT-
telephones or wireless headphones.
Users should pay particular attention to the risk of disruption from products which communicate
using the same or adjacent frequencies.
For further information, please contact your supplier.
2.1
Medical units
The use of equipment that transmits radio signals, for example, mobile phones, can interfere with
insufficiently protected medical equipment. Consult a doctor or the manufacturer of the equipment
to determine if it has adequate protection against external radio signals, or if you have any questions.
If notices have been put up at health care facilities instructing you to turn off the unit while you are
there, you should comply. Hospitals and other health care facilities sometimes use equipment that
can be sensitive to external radio signals.
