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 device  is used exceeds 

the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal 

performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.

The device is intended for use in the electromagnetic environment specified below. The

customer or the user of the device 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 

device, including cables, than the 

recommended separation distance 

calculated from the equation 

applicable to the frequency of the

The device  is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. 
The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum 
distance between portable and mobile RF communications equipment (transmitters) and the  device as recommended 
below, according to the maximum output power of the communications equipment.
