Interference may occur in the vicinity of equipment marked with the following symbol:
Notes
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
a
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 675 is used exceeds the applicable RF compliance level above, the model 675 should be observed to verify
normal operation� If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
model 675�

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m�
Recommended separation distances between portable and mobile RF communications equipment and the model 675
The model 675 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled� The customer or
the user of the model 675 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the model 675 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�
Notes
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies�
These guidelines may not apply in all situations� Electromagnetic propagation is affected by absorption and reflection from structures,
