EasyStand Glider, Руководство пользователя, Страница: 17 / 28

Portable and mobile RF communications equipment
should be used no closer to any part of the Easystand
Glider, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.

Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The Easystand Glider is intended for use in the electromagnetic environment specified below. The customer or the
user of the Easystand Glider should assure that it is used in such an environment.

Electromagnetic Environment - Guidance
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.

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 Easystand Glider is used exceeds the
applicable RF compliance level above, the Easystand Glider should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Easystand Glider.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
