GUIDANCE AND MANUFACTURER’S DECLARATION
ELECTROMAGNETIC IMMUNITY
The Scanmate Flex is intended for use in the electromagnec environment specied below. The customer
or the user of the Scanmate Flex should assure that it is used in such an environment.

Portable and mobile RF communicaons
equipment should be used no closer to any
part of the Scanmate Flex, including cables,
than recommended separaon distance
calculated from the equaon applicable to
the frequency of the transmier.
Recommended separaon distance
150 kHz—80 MHz
80 MHz—800MHz
800 MHz—2.5 GHz
where P is the maximum output power
rang of the transmier in was (W)
according to the transmier manufacturer
and d is the recommended separaon
distance in meters (m).
Field strengths from xed RF transmiers,
as determined by an electromagnec 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 situaons. Electromagnec propagaon is aected by
absorpon and reecon from structures, objects and people.
a
Field strengths from xed transmiers, such as base staons for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theorecally with accuracy. To assess the electromagnec environment due to xed RF
transmiers, an electromagnec site survey should be considered. If the measured eld strength in
the locaon in which the Scanmate Flex is used exceeds the applicable RF compliance level above,
the Scanmate Flex should be observed to verify normal operaon. If abnormal performance is
observed, addional measures may be necessary, such as re-orienng or relocang the Scanmate
Flex.

Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than [V
