Vision System
Table 1-3 Guidance and Manufacturer's Declaration - Electromagnetic Immunity - The Constellation
®
Vision System is intended for use in the electromagnetic environment specified below. The
customer or the user of the Constellation
®
Vision System should assure that it is used in
such an environment.
Immunity Test IEC 60601 Test Level Compliance Level Electromagnetic Environment-Guidance
Electrostatic
discharge (ESD)
IEC 61000-4-2
• ±6 kV contact
• ±8 kV air
• ±6 kV contact
• ±8 kV air
Floors should be wood, concrete, or ceramic tile. Do
not use around floors that are covered with synthetic
material to avoid laser stoppage due to ESD.
Electrical fast
transient/burst
IEC 61000-4-4
• ±2 kV for power
supply lines
• ±1 kV for input/output
lines
• ±2 kV for power
supply lines
• ±1 kV for input/
output lines
Mains power quality should be that of a typical
commercial or hospital environment. To avoid laser
stoppage due to fast transients avoid powering the
Constellation® Vision System on the same branch
circuit with sources that can generate fast transients
(inductive switching; e.g., high current motors).
Surge
IEC 61000-4-5
• ±1 kV differential
mode
• ±2 kV common mode
• ±1 kV differential
mode
• ±2 kV common
mode
Mains power quality should be that of a typical
commercial or hospital environment. To avoid
laser stoppage due to power-line surges consider
powering the
Constellation® Vision System through
branch circuit that has surge suppressor for
protection against lightning surges (e.g., at power
panel to surgical/office suite).
Voltage dips, short
interruptions, and
voltage variations

• <5% (>95% dip in

) for 5 sec
Mains power quality should be that of a typical
commercial or hospital environment. If the uses of
the Constellation® Vision System require continued
operation during power mains interruptions, it is
recommended that the Constellation® Vision System
be powered from an uninterruptible power supply
or a battery.

levels characteristic of a typical location in a typical
commercial or hospital environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the
Constellation® Vision System, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency to
the transmitter.
Recommended separation distance:
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.5 GHz

where P is the maximum output power rating to the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
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 following symbol.
Note: U
T
is the a.c. mains voltage prior to application of the test level.
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) and land mobile radios, amateur radio, AM and
FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To access 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 Constellation® Vision System is used exceeds the applicable RF compliance level above, the Constellation® Vision
System should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the Constellation® Vision System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
