compatibility
The Dr. Mach OT- and examination lights are subject to special preventive measures regarding the elec-
tromagnetic compatibility and must be installed according to the EMC-instructions mentioned in the ac-
companying documents.
The function of the OT- and examination lights can be affected by portable and mobile HF-communication
devices.
