For transmitters rated at a maximum output power not listed in the above table, the recommended separa-
tion distance d in meters (m) can be determined using the equation indicated for each column, with P being
the maximum output power rating of the transmitter in watts (W) according to the transmitter manufac-
turer's specifications.

The device S7 / OPMI VISU 160 is intended for use in an electromagnetic en-
vironment in which RF disturbances are controlled. The customer or the user
of the device S7 / OPMI VISU 160 can help prevent electromagnetic interfer-
ence by maintaining a minimum distance between portable and mobile RF
communication equipment (transmitters) and the S7 / OPMI VISU 160 - de-
pending on the output power of the communication equipment as specified
below.
