G - 6 Operator’s Manual
G EMC Guidance and Manufacturer’s Declaration
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 system is used
exceeds the applicable RF compliance level above, system should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the system.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.
Table G-5
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE
RF COMMUNICATION DEVICE AND THE SYSTEM
The system is intended for use in an electromagnetic environment in which radiated RF
disturbance are controlled. The customer or the user of system can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communication
equipment (transmitters) and system as recommended below, according to the maximum output
power of the communication equipment.

1 1.2 0.35 0.7
10 3.8 1.11 2.22
100 12 3.5 7
For transmitters at a maximum output power not listed above, the recommended separation
distanced in meters (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.
If system image distortion occurs, it may be necessary to position system further from sources of
conducted RF noise or to install external power source filter to minimize RF noise to an
acceptable level.
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.
