Guidance and manufacturer’s declaration - electromagnetic immunity
The STRYKER SYSTEM G Rotary Drill (REF 7305-001-000) is intended for use in the electromagnetic environment specified below. The customer or the
user of the STRYKER SYSTEM G Rotary Drill (REF 7305-001-000) 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 STRYKER SYSTEM G Rotary Drill (REF 7305-001-000), 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,

should be less than the compliance level in each
frequency range.

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 Rotary Drill (REF
7305-001-000) is used exceeds the applicable RF compliance level above, the STRYKER SYSTEM G Rotary Drill (REF 7305-001-000) should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the STRYKER
SYSTEM G Rotary Drill (REF 7305-001-000).
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the STRYKER SYSTEM G Rotary Drill (REF
7305-001-000)
The STRYKER SYSTEM G Rotary Drill (REF 7305-001-000) is intended for use in the electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the STRYKER SYSTEM G Rotary Drill (REF 7305-001-000) can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the STRYKER SYSTEM G Rotary Drill
(REF 7305-001-000) as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in meters (m) can be estimated using the
equation applicable to the frequency of the transmitter, where
P
is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1: At 80 MHz and 800MHz, the separation distance for 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.
