Guidance and Manufacturer’s Declaration – Electromagnetic Emissions
POC-W243 series terminals are intended for use in the electromagnetic environment spec -
ified below. The customer or user of the POC-W243 series should assure that it is used in
such an environment.
Emissions test Compliance
Electromagnetic environment –
guidance
RF emissions
CISPR 11
Group 1
The POC-W243 series uses RF
energy only for its internal func -
tion. Therefore, its RF emissions
are very low and are not likely to
cause any interference in nearby
electronic equipment.
RF emissions
CISPR 11
Class B
The POC-W243 series is suitable
for use in all establishments,
including domestic establishments
and those directly connected to
the public low-voltage power sup -
ply network that supplies buildings
used for domestic purposes.
Harmonic emissions
IEC 61000-3-2
Class A
Voltage fluctuations/
flicker emissions
IEC 61000-3-3
Not applicable
Recommended separation distances between
portable and mobile RF communications equipment and the POC-W243 series
POC-W243 series terminals are intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or user can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and POC-W243 terminals as recom -
mended below, according to the maximum output power of the communications equip -
ment.

For transmitters rated at a maximum output power not listed above, the recommended sep -
aration distance d in meters (m) can be estimated using the equation applicable to the fre -
quency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for 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.
