Recommended separation distances between portable and mobile
RF communication equipment and the device.
The device is intended for use in an electromagnetic environment
where radiated RF disturbances are under control. User can help
prevent electromagnetic interference by keeping the device at a mi

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in metres (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.
