CHAPTER 4 - INSTALLATION

4.5. Electromagnetic interference

• Operation in close proximity (i.e. less than 2
metres) to working shortwave or microwave
therapy units may produce instability in the
ELTRAC 471 output.
• To prevent electromagnetic interference, we
strongly advise using separate mains groups
(phases) for the ELTRAC 471 and the shortwave
or microwave equipment, and a distance of at
least 2 metres is kept between the ELTRAC 471
and the shortwave or microwave equipment.
• Ensure that the mains cable of the shortwave/mi-
crowave unit does not come near the Endomed
or the patient.
If problems with electromagnetic interference per-
sist, please contact your authorised distributor.
