Recommended distances between portable and mobile RF communications equipment
The ri-­scope L is intended for use in an electromagnetic environment in which RF emissions
are controlled. The customer or user of the ri-­scope L can help to avoid electromagnetic
interference by observing the minimum distance between portable and mobile RF
communications equipment (transmitters) and the ri-­scope L in accordance with the maximum
output power of the communication equipment.

For transmitters with a maximum output power not listed above, the recommended distance d
in metres (m) can be estimated using the equation for the transmitter frequency, where P is the
maximum output power of the transmitter in watts (W). according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance applies to the higher frequency
