Resonance r25c User Manual

Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is aected by
absorption and reection from structures, objects and people.
a. Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be considered. If the measured eld
strength in the location in which the R25C/R35C is used exceeds the applicable RF compliance level
above, the R25C/R35C should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as re-orienting or relocating the R25C/
R35C.
b. Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.

Test level
Mains power quality should be
that of a typical commercial or
hospital environment. If the
user of the R25C/R35C requires
continued operation during
power mains interruptions. it is
recommended that the R25C/
R35C be powered from an
uninterruptible power supply
or a battery.
