Guidance and MANUFACTURER’S declaration – electromagnetic IMMUNITY –
FOR ME EQUIPMENT THAT ARE NOT LIFE-SUPPORTING
The ME EQUIPMENT is intended for use in the electromagnetic environment specified below.
The customer or the user of the ME EQUIPMENT should assure that it is used in such an
environment.

Portable and mobile RF communications equipment should be used no closer to any part of
the ME EQUIPMENT, including cables, than the recommended separation distance calculated
from 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 and d is the recommended separation distance in metres (m). Field
strengths from fixed RF transmitters, as determined by an electromagnetic site survey,*1
should be less than the compliance level in each frequency range.*2
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.
*1: 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 ME
EQUIPMENT is used exceeds the applicable RF compliance level above, the ME EQUIPMENT
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the ME EQUIPMENT .
*2: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Recommended separation distances between portable and mobile RF communications equipment
and the ME EQUIPMENT
The ME EQUIPMENT is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled.
The customer or the user of the ME EQUIPMENT can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the ME EQUIPMENT 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 metres (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.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
