Appendix
The customer or the user of RadiForce MX317W can suppress interference caused by
proximity magnetic fields by maintaining a minimum distance (15 cm) between the RF
transmitter and RadiForce MX317W. RadiForce MX317W has been tested at the following
compliance levels (C) for the required test levels (T) of proximity magnetic field immunity.
Test frequency
30 kHz
134.2 kHz

*1
The carrier is modulated using a 50 % duty cycle square wave signal.
For other portable and mobile RF communication equipments (transmitters), minimum
distance between portable and mobile RF communications equipment (transmitters) and
RadiForce MX317W as recommended below, according to the maximum output power of
the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance "d" in meters (m) can be estimated 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
• At 80 MHz and 800 MHz, the separation distance for a higher frequency range must be applied.
• These guidelines regarding conducted disturbances induced by RF fields or radiated RF fields
may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
