5.1.3. Recommended Separation Distance
Recommended separation distances between portable and mobile RF commu-
nications equipment and the AtriCure RF, Cryo, and EP Mapping System
The AtriCure RF, Cryo, and EP Mapping System (ARC-EPMS) is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the ARC-EPMS
can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the ARC-EPMS 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 dis-
tance 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.
5.1.4. Responsibility of the Manufacturer
AtriCure is responsible for safety, reliability, and performance of the equipment only if:
• Installation procedures in this manual are followed.
• Persons authorized by AtriCure carry out modifications or repairs.
• The electrical installation of the relevant room complies with local codes
and regulatory requirements such as IEC and BSI.
• The equipment is used in accordance with the AtriCure User's Manual.
