JVC BD-X201M manual Recommended separation distance

Guidance or Manufacturer’s declaration-electromagnetic immunity

The Model BD-X201MEis intended for use in the electromagnetic environment specified below.

The customer or the user of the Model BD-X201MEshould assure that it is used in such an environment.

Immunity Test	IEC/EN 60601	Compliance	Electromagnetic environment-guidance

			Field strengths from fixed RF transmitters, as

			Interference may occur in the vicinity of equip-

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the mea- sured field strength in the location in which the Model BD-X201MEis used exceeds the applicable RF compliance level above, the Model BD-X201MEshould be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Model BD-X201ME.

bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distance between portable and mobile RF communi-

cations equipment and the Model BD-X201ME

The Model BD-X201MEis intended for use in the electromagnetic environment in which radiated RF distur- bances are controlled. The customer or the user of the Model BD-X201MEcan help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Model BD-X201MEas 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 watt (W) according to the transmitter manufacturer.

NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
