Recommended Separation Distances
Recommended Separation Distances Between Portable/Mobile RF Communications Equipment and the
Product
This product is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled.
The customer or the user of this product can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the product
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.
Separation Distance Notes
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.
WARNING: Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the (ME EQUIPMENT or ME SYSTEM),
including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment
could result.
WARNING: Combinations of accessories that are not listed in the instruction manual may only be used if they are
intended exclusively for a given use and do not affect the performance, safety, and EMC characteristics of the
medical device.
