Field strengths from fixed transmitters, such as base stations for
radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the
location in which the CMS70A is used exceeds the applicable RF
compliance level above, the CMS70A should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the
CMS70A.

Over the frequency range 150 kHz to 80 MHz, field strengths
should be less than 3 V/m .

The CMS70A is intended for use in an
electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the
user of the CMS70A can help prevent
electromagnetic interference by maintaining a
minimum distance between portable and mobile RF
communications equipment (transmitters) and the
CMS70A as recommended below, according to the
maximum output power of the communications
equipment.
