Recommended Separation Distances for Portable and Mobile RF Communications Equipment IEC
60601-1-2
The OP 3D Pro is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The user of OP 3D Pro can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the OP 3D Pro as
recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at 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.
NOTICE!
At 80 MHz, the separation distance for the higher frequency range applies.
NOTICE!
These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
WARNING!
*** Portable RF communications equipment (including peripherals such as antenna
cables and external antennas) should be used no closer than 30 cm (12") to any part of the device,
including cables specified by the manufacturer. Otherwise, degradation of the performance of this
equipment could result. See
on page 112.
USE LIMITATION:
External components
WARNING!
Use of accessories, transducers and cables other than those specified
or provided by the manufacturer of this equipment could result in increased
electromagnetic emissions or decreased electromagnetic immunity of this device
and result in improper operation.
INSTALLATION REQUIREMENTS & ENVIRONMENT CONTROL:
In order to minimize interference risks, the following requirements shall apply.
Cables shielding & grounding
All interconnect cables to peripheral devices must meet the requirements given in
on page 92. Use of incorrect cables may result in the device
causing radio frequency interference.
Electrostatic discharges environment & recommendations
In order to reduce electrostatic discharge interference, a charge dissipative floor should
be installed to prevent charge accumulation.
● The dissipative floor material must be connected to the system reference ground, if
applicable.
● Relative humidity must be maintained above 30 percent.
