Recommended separation distances between
portable and mobile RF communications equipment and the model POC-W181
Model POC-W181 is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the model POC-W181 can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the model POC-W181 as rec-
ommended 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 sepa-
ration 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.
Electromagnetic environment - guidance
The model POC-W181 uses RF energy only
for its internal function. Therefore, its RF emis-
sions are very low and are not likely to cause
any interference in nearby electronic equip-
ment.
The model POC-W181 is suitable for use in all
establishments, including domestic establish-
ments and those directly connected to the pub-
lic low-voltage power supply network that
supplies buildings used for domestic pur-
poses.
