GUIDANCE and MANUFACTURER’S
DECLARATION - ELECTROMAGNETIC IMMUNITY
The TOC is intended for use in the electromagnetic environment specified
below. The user of the TOC should make sure it is used in such an environ-
ment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the TOC, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance:
d=1.2√P 150 kHz to 80 MHz
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
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey a,
should be less than the compliance level in each
frequency range b.
Interference may occur in the vicinity of
equipment marked with the following symbol:
