SPECIFICATIONS (CONTINUED)
Guidance and manufacturer's declaration - electromagnetic immunity
The SMRT Charger is intended for use in the electromagnetic environment specified below. The customer or
the user of the SMRT Charger should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF
IEC 61000-4-3 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 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 SMRT Charger
is used exceeds the applicable RF compliance level above, the SMRT Charger should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the SMRT Charger.
b Over the frequency range 150 kHz to 80 MHz, field strengths are less than 20 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the SMRT Charger, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d=1.17√P
d=1.17√P
80 MHz to 800 MHz
d=2.33√P
800 MHz to 2.5 GHz
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 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:
