Recommended safety distances between portable and mobile RF communication
equipment and the EXTARO 300
The device EXTARO 300 is intended for use in an electromagnetic environment in which RF disturbances
are controlled. The customer or the user of the device EXTARO 300 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communication
equipment (transmitters) and the EXTARO 300 depending on the output power of the communication
equipment as specified below.

For transmitters rated at a maximum output power not listed in the above table, the
recommended separation distance d in meters (m) can be determined using the equation
applicable to the frequency of the transmitter, with P being the maximum output power rating of
the transmitter in watts (W) according to the transmitter manufacturer’s specifications.
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
influenced by absorption and reflection by structures, objects and persons.
11.8.5
Use of class A device
Note: the EMISSIONS characteristics of this equipment make it suitable for use in industrial areas and
hospitals (CISPR 11 class A). If it is used in a residential environment (for which CISPR 11 class B is
normally required) this equipment might not offer adequate protection to radio-frequency
communication services. The user might need to take mitigation measures, such as relocating or re-
orienting the equipment.
