MHX 920 Operating Manual: Chapter 2 Configuration 5
WARNING
In order to comply with the
FCC/IC adopted RF
exposure requirements, this
transmitter system will be
installed by the
manufacturer's reseller
professional. Installation of
all antennas must be
performed in a manner that
will provide at least 23 cm
clearance from the front
radiating aperture, to any
user or member of the
public.
IMPORTANT:
FCC Regulations allow up to 36 dBi effective radiated power (ERP).
Therefore, the sum of the transmitted power (in dBm), the cabling loss
and the antenna gain cannot exceed 36 dBi.
1 mW = 0 dBm
10 mW = 10 dBm
100 mW = 20 dBm
1000 mW = 30 dBm
For example, when transmitting 1 Watt (30 dBm), with cabling losses of
2 dB, the antenna gain cannot exceed 36 - 30 + 2 = 8 dBi. If an antenna
with a gain higher than 8 dBi were to be used, the power setting must be
adjusted appropriately. Violation of FCC regulations can result in
severe fines.
