Guidance and manufacturer's declaration - electromagnetic immunity
The Bluephase Style M8 is intended for use in the electromagnetic environment specified below. The customer or the user of the Bluephase Style M8
should assure that it is used in such an environment.

Recommended separation distances between portable and mobile RF communications equipment
and the "Bluephase Style M8"
The Bluephase Style M8 is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the Bluephase Style M8 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Bluephase Style M8 as recommended below, according to the maximum output power of the
communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be determined using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should not be used
closer to any part of the Bluephase Style M8, including cables, than the
recommended separation distance caculated from the equation applica-
ble to the frequency of the transmitter.

Interference may occur in the vicinity of equipment marked with the
following symbol:
ment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the Bluephase Style M8 is used exceeds the
applicable RF compliance level above, the Bluephase Style M8 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be neces-
sary, such as reorienting or relocating the Bluephase Style M8.
