should be monitored to confirm it is functioning as intended. If unusual performance characteristics are observed,
additional measures may be required such as repositioning the 743A250 Bionic Pro product or moving it to a dif
ferent location.

Recommended safety distances between portable and mobile HF telecommunication equipment and the
743A250 Bionic Pro product
The 743A250 Bionic Pro product is designed for operation in an electromagnetic environment where HF interfer
ence is controlled. The customer or user of the product can help prevent electromagnetic interference by main
taining the minimum distance – which depends on the output of the telecommunication device as specified below
– between portable and mobile HF telecommunication equipment (transmitters) and the product.

For transmitters with no maximum nominal output specified in the table above, the recommended safety distance
d in metres (m) can be determined using the equation in the respective column, where P stands for the maximum
nominal output of the transmitter in watts (W) according to the transmitter manufacturer's information.
NOTE 1: The higher frequency range applies at 80 MHz and 800 MHz.
NOTE 2: These directives may not be applicable in all cases. The propagation of electromagnetic factors is influ
enced by absorption and reflection by buildings, objects and people.
