The 901103 is intended for use in the electromagnetic environment specified below. The customer or the user of the
901103 should assure that it is used in such an environment.

Note1: At 80 MHz and 800 MHz, 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.

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 901103 is used exceeds the applicable RF

Mains power quality should be that of a typical
commercial or hospital environment. If the user
of the 901103 requires continued operation
during power mains interruptions, it is
recommended that the 901103 be powered
from an uninterruptible power supply or a
battery.

Portable and mobile RF communications
equipment should be used no closer to any part
of the 901103, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
