WARNING: Interference may occur in the vicinity of
equipment marked with this symbol. This
equipment/system may cause radio interference or
may disrupt the operation of nearby equipment. It
may be necessary to take mitigation measures such as:
• Reorient or relocate the receiving device.
• Increase the separation between the equipment.
Conducted RF IEC
61000-4-6
0.15-80 MHz, 3Vrms, 80% 1 KHZ
AM
Portable and mobile RF communications
equipment should be used no closer to any
part of the RetCam system, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d= (3.5/ E1)x(square root of P) 80 MHz to
800 MHz
d= (7 /E1)x(square root of 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). E1 is 3 V/m
Conducted Immunity:
d= (3.5/ V1)x(square root of P) where V1 is
3 Vrms
Field strength from fixed RF transmitters, as
determined by an electromagnetic site
survey, should be less than the compliance
level in each frequency range. Interference
may occur in the vicinity of equipment
marked with the following symbol.
Radiated Immunity
EN 61000-4-3
80MHz-2.5GHz
3V/m 80%@1kHz
Magnetic Immunity
EN 61000-4-8
3A/m 50/60 Hz Video display terminals and other electron
beam devices (e.g. X-ray image intensifiers)
may use a justification for lower IMMUNITY
COMPLIANCE LEVELS as allowed by
36.202.1 a).
