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 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 ORCHESTRA PLUS LINK is used exceeds the applicable RF
compliance level above, the ORCHESTRA PLUS LINK should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting, relocating the ORCHESTRA PLUS LINK, or use inductive telemetry.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
15.3 RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE ORCHESTRA PLUS LINK
The ORCHESTRA PLUS LINK is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The user of the ORCHESTRA PLUS LINK
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the ORCHESTRA
PLUS LINK 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 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.
