NOTE
• 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).
• This instrument complies with the requirements of
IEC 60601-1-2: 2001. However, under
electromagnetic environment that exceeds its noise
level, electromagnetic interference may occur to this
instrument.

NOTE
The guidance may not apply in some situations.
Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
Portable and mobile RF communications equipment
such as cellular phones should be used no closer to any
part of this instrument, including cables than the
recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
