Guidance and manufacturer’s declaration - electromagnetic immunity
The STRYKER SYSTEM G Charger, 2-Bay (REF 7310-120-000) is intended for use in the
electromagnetic environment specified below. The customer or the user of the STRYKER SYSTEM
G Charger, 2-Bay (REF 7310-120-000) should assure that it is used in such an environment.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the STRYKER SYSTEM G Charger,
2-Bay (REF 7310-120-000), including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
150 kHz to 80 MHz
80 MHz to 800 MHz
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 [ V
1
and E
1
]. b Interference may occur
in the vicinity of equipment marked with the
following symbol:
(Non-ionizing electromagnetic
radiation)
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to
80 MHz
[ V
1
] = 3 Vrms
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to
2.5 GHz
[ E
1
] = 3 V/m
NOTE 1: At 80 MHz and 800MHz 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 STRYKER SYSTEM G Charger, 2-Bay (REF 7310-120-000) is used exceeds
the applicable RF compliance level above, the STRYKER SYSTEM G Charger, 2-Bay (REF 7310-120-
000) should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating STRYKER SYSTEM G Charger, 2-Bay
(REF 7310-120-000).
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
