Note 1: At 80 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 in the presence of fixed RF transmitters, an electromagnetic site survey should be considered. If the
measurement field strength in the location in which the T7 is used exceeds the applicable RF compliance level above, the T7 should
be observed to verify normal operations. Abnormal performance measures may be necessary, such as reorienting or relocating the T7.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 Vrms.
Do not dispose of the T7 or any associated components at the end of service life. Contact Humanscale
