The mains power quality should correspond to that
of a typical commercial or hospital environment.
To ensure continuous operation of the
CHROMOPHARE

lights, they must be connected to
an uninterruptible power supply in accordance with
DIN VDE 0100-710.
Radiated RF fields

3 V/m,
80 MHz to 2.5 GHz
For image distortion in lights with a built-in camera
system, move the source of the electric fields
further away from the lights or install shielding.
