9.6.2. Recommended to Separate Distances
Recommended separation distances between portable and mobile RF communications
equipment and the TA80V Animal Anesthesia Workstation
The TA80V Veterinary anesthesia workstation should be used in a radiation-controlled
electromagnetic environment. Customers or users of the TA80V Animal Anesthesia Workstation can
follow the recommendations below to prevent electromagnetic interference by maintaining a certain
distance between portable, mobile RF communications equipment and the TA80V Animal
Anesthesia Workstation based on the maximum output power of the communication device.

If the rated maximum output power of the transmitter exceeds the above range, the separation
distance d (unit: meter) can be determined using the formula applicable to the transmitter
frequency. Here, P is the rated maximum output power of the transmitter. According to the
transmitter manufacturer's Specified, the unit is W (watt).
NOTE 1 From 80MHz to 800MHz, the separation distance for the high frequency range applies.
NOTE 2 The ISM (Industrial, Scientific and Medical) bands between 150kHz and 80MHz are
6.765MHz to 6.795MHz, 13.553MHz to 13.567MHz; 26.957MHz to 27.283MHz; and
40.66MHz to 40.70MHz.
NOTE 3 For the ISM frequency band between 150 kHz and 80 MHz and the frequency range 80
MHz and 2.5 GHz, an additional factor of 10/3 is applied when calculating the recommended
separation distances for transmitters in these frequency ranges, for the purpose of ensuring that
mobile/portable communications equipment Reduce the potential for the device to cause
interference if it is inadvertently introduced into an animal area.
NOTE 4 These guidance information may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection by buildings, objects and people.
