and "Bluephase Style G4"
Bluephase G4 is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
Bluephase G4 can help prevent electromagnetic interference by maintaining a miminum distance between portable and mobile RF communications
equipment (transmitters) and Bluephase G4 as recommended below, according to the maximum out-put power of the communication equipment.

Table: According to IEC60601-1-2
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 Bluephase G4, including cables, than the
recommended separation distance caculated from the equation
applicable to the frequency of the transmitter.

exceeds the applicable RF compliance level above, Bluephase G4 should be observed to
verify normal operation. If abnormal performance is ob-served, additional measures may be
necessary, such as reorienting or relocating Bluephase G4.
