MITSUBISHI ELECTRIC P93DE - Manual (Page 7)

Guidance and manufacturer's declaration - electromagnetic immunity
The Model P93DW/P93DE is intended for use in the electromagnetic environment specified below.
The customer or user of the Model P93DW/P93DE should assure that it is used in such an
environment.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the Model P93DW/P93DE,
including cables, than the recommended
separation distance calculated from the
equation applicable to frequency of the
transmitter.

where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
a should be
less than the compliance level in each
frequency range.

Interference may occur in the vicinity of
equipment marked with the following
symbol:
Compliance
level
3 Vrms
3 V/m
NOTE1. At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2. These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
a Field 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 measured field strength in the location in which the Model P93DW/P93DE
is used exceeds the applicable RF compliance level above, the Model P93DW/P93DE
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Model
P93DW/P93DE.
b Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
