Instruction Manual Binoptometer® 4P (G/59860/1016/en)
Recommended separation distances between portable and mobile
RF communications equipment and the Binoptometer® 4P,
IEC 60601-1-2, 5.2.2.2, table 6
The Binoptometer® 4P in intended for us e in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Binoptometer® 4P can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters ) and the Binoptometer® 4P 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 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.
