recommended separation distance in

meters (m).

Field strengths from fixed RF

transmitters, as determined by an

electromagnetic site survey*, should

be less than the compliance level in

each frequency range.** Interference

may occur in the vicinity of equipment

marked with the following symbol:

*Electromagnetic site survey- Field strengths from fixed transmitters, such as base stations for

radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio

broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the

electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should

be considered. If the measured field strength of the location in which the Merlin PSA is used

exceeds the applicable RF compliance level above, the Merlin PSA should be observed to verify

normal operation. If abnormal performance is observed, additional measures may be necessary,

such as re-orienting or relocating the Merlin PSA.

**Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than [V

]V/m.

NOTE: The Merlin PCS is intended for use in an electromagnetic environment in which

radiated RF disturbances are controlled. The user of the Merlin PCS can help prevent

electromagnetic interference by maintaining a minimum distance between portable and

These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from

structures, objects, and people.

At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
