GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
Guidance and manufacturer’s declaration – electromagnetic immunity
The BTL Vanquish ME is intended for use in the electromagnetic environment specified below. The
customer or the user of the BTL Vanquish ME should assure that it is used in such an environment.

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

where P is the maximum output power rating of

transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
a)
,
should be less than the compliance level in each
frequency range
b)
.
Interference may occur in the
vicinity of equipment marked with
the following symbol:
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 affected
by absorption and reflection from structures, objects and people.
a) 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 BTL Vanquish ME is used exceeds the applicable RF
compliance level above, the BTL Vanquish ME should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the BTL Vanquish ME.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
