4. Follow the Good Engineering Practices and be a Good RF Neighbor - Good
engineering practice must be used in regard to the signal booster’s noise radiation.
Accordingly, the gain of the signal booster should be set so that the ERP of the output noise
from the signal booster should not exceed the level of -43 dBm in 10 kHz measurement
bandwidth. In the event that the noise level measured exceeds that value, the signal
booster gain should be decreased accordingly. Also, please note that in general, the ERP of
noise on a spectrum more than 1 MHz outside of the pass band should not exceed -70 dBm
in a 10 kHz measurement bandwidth.

5. Set the Booster Gain using the procedure described on page 10 to the value as
determined by following the step 3 and 4. System gain can be further reduced if required by
specific site conditions or factors.

7. Power up the Booster and Test the Coverage.
Class B broadband signal boosters are
permitted to be used only in confined or indoor areas such as buildings, tunnels,
underground areas, etc., or in remote areas, i.e., areas where there is little or no risk of
interference to other users.
