Guidance and manufacturer ' s declaration - electromagnetic immunity

The KD-557BT is intended for use in the electromagnetic environment specified below. The customer or

the user of the KD-557BT should assure that it is used in such an environment.

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

KD-557BT is used exceeds the applicable RF compliance level above, the KD-557BT should be observed

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