Electrostatic discharge
(ESD) IEC 61000-4-2
±8 kV contact
±2, 4, 8, 15 kV air
±8 kV contact

Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material, the relative humidity
should be at least 30%.
Transient/sequence of
rapid electrical pulses
IEC 61000-4-4
±2 kV for power
supply lines
±1 kV for I/O lines
±2 kV for power
supply lines
Not applicable
The quality of the mains voltage should
be that of a typical commercial or hospital
environment.
In case of 2 kV bursts on the power
supply line, a malfunctioning of the
selected fixation LED may occur, move
the power supply to a free socket to which
no other devices are connected.

The quality of the mains voltage should
be that of a typical commercial or hospital
environment. If the Retina800 user
requires continued operation during mains
power outages, it is recommended to use
Retina800 with an uninterruptible power
supply or batteries.

IEC 61000-4-8
30 A/m
Not applicable, the
device does not
contain components
susceptible to
magnetic fields.
Magnetic fields should be at levels
characteristic of a typical location in a
typical commercial or hospital
environment.
