Mains power quality
should be that of a
typical commercial or
hospital environment. If
the user of the 2in1. BP
TELE requires continued
operation during power
mains interruptions,
it is recommended
that the 2in1. BP TELE
be powered from an
uninterruptible power
supply or a battery.

Guidance and manufacturer’s declaration-electromagnetic immunity
The 2in1. BP TELE is intended for use in the electromagnetic environment specified below. The cus-
tomer or the user of the 2in1. BP TELE should assure that is used in such and environment.

Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in metres (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 2in1. BP TELE is used exceeds the applicable RF compliance
level above, the 2in1. BP TELE should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating
the 2in1. BP TELE.
b: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
