SPECIFICATIONS AND PERFORMANCE

Guidance and manufacturer's declaration - electromagnetic immunity

The RM-8900,KR-8900 is intended for use in the electromagnetic environment specified below.

The customer or the user of the RM-8900,KR-8900 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 RM-8900,KR-8900, including

cables, than the recommended separation

distance calculated from the equation appli-

cable to the frequency of the transmitter.

Recommended separation distance

d = 1.2

d = 1.2 80MHz to 800MHz

d = 2.3 800MHz to 2, 5GHz

where P is the maximum output power rat-

ing of the transmitter in watts (W) accord-

ing 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,

should be less than the compli-

ance level in each frequency range.

Interference may occur in the vicinity of

equipment marked with the following symbol:

NOTE 1

NOTE 2

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

These guidelines may not apply in all situations. Electromagnetic propagation is

affected by absorption and reflection from structures, objects and people.

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 con-

sidered. If the measured field strength in the location in which the RM-8900,KR-8900 is

used exceeds the applicable RF compliance level above, the RM-8900,KR-8900 should

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

measures may be necessary, such as reorienting or relocating the RM-8900,KR-8900.

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