Recommended separation distances between portable and mobile RF
communications equipment and the A7+ TouchCare® System
The A7+ TouchCare® System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or user of the A7+ TouchCare® System can help prevent
electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the
A7+ TouchCare® System 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: At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
Warning:
1. EMC (Electromagnetic Compatibility) information in this guide should be
referred before installing and using the A7+ TouchCare® System.
2. The A7+ TouchCare® System is not designed to be used in an environment
with high voltage, high-intensity magnetic field, where the intensity of EM
DISTURBANCES is high.
3. Portable RF Communications equipment should be used no closer than 30 cm
(12 inches) to any part of the Medtrum products. Otherwise, degradation of the
performance of this equipment could result.
