Guidance and manufacturer's declaration-electromagnetic immunity
CF-VCBU11U is intended for use in the electromagnetic environment specifi ed below. The
customer or user of the CF-VCBU11U should assure that is used in such an environment.
Immunity test IEC60601 test
level
Conducted RF 3 Vrms
IEC61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC61000-4-3 80 MHz to 2.5 GHz
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
effected by absorption and refl ection from structures, objects and people.
* Field strengths from fi 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 fi xed RF transmitters, an electromagnetic site survey should be
considered. If the measured fi eld strength in the location in which the Model CF-VCBU11U is
used exceeds the applicable RF compliance level above, the Model CF-VCBU11U should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Model CF-VCBU11U.
* Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.

Compliance Electromagnetic environment-
level guidance
3 V Portable and mobile RF
communications equipment should be
used no closer to any part of the Model
3 V/m CF-VCBU11U, including cables, than
the recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance:
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.5 GHz
Where P is the maximum output power
rating of the transmitter in watts
according to the transmitter
manufacturer and d is the
recommended separation distance in
meters.
Field strengths from fi xed RF
transmitters, as determined by an
electromagnetic site survey *
be less than the compliance level in
each frequency range. *
