Guidance and manufacturer’s declaration - electromagnetic immunity
The DR-ID 900PU is intended for use in the electromagnetic environment specified below.
The customer or the user of the DR-ID 900PU should assure that they are used in such an environment.

900PU, including cables, than the recommended
separation distance calculated from the equation

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 metres (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.
b
Interference may occur in the vicinity of equipment
marked with the following symbol:
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.
a Field strength 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 DR-ID 900PU is used exceeds
the applicable RF compliance, the DR-ID 900PU should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the DR-ID
900PU.
b Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
