Guidance and manufacturer’s declaration - electromagnetic immunity

The FlexScan L760T-C is intended for use in the electromagnetic environment specified below. The

customer or the user of the FlexScan L760T-C should assure that it is used in such an environment.

Portable and mobile RF

communications equipment should

be used no closer to any part of

the FlexScan L760T-C, including

cables, than the recommended

separation distance calculated from

the equation applicable to the

frequency of the transmitter.

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

be less than the compliance level in

.

Interference may occur in the

vicinity of equipment marked with

the following symbol.

NOTE 1 At 80 MHz and 800 MHz, 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.

a

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 in the location in which

the FlexScan L760T-C is used exceeds the applicable RF compliance level above, the FlexScan L760T-C

should be observed to verify normal operation. If abnormal performance is observed, additional

measures may be necessary, such as reorienting or relocating the FlexScan L760T-C.

b

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
