Warning:
This BT-720 is intended for use by healthcare
professionals only. This equipment/ system may cause
radio interference or may disrupt the operation of nearby
equipment. It may be necessary to take mitigation
measures, such as re-orienting or relocating the BT-720 or
shielding the location.

15.2 Recommended separation distances between portable and mobile RF communications
equipment and BT-720
The BT-720 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the BT-720 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the BT-720 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 meters (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.
