Test by adjusting the transmitted signal strength by
decreasing/increasing the 'Transmit Level' setting in steps
of 1db. For example, if default value is -11 db, changing it
to-12db will decrease the signal strength by 1db, and
changing it to -10db will increase the signal strength by
1db. Recommended adjustment range is ±5 db (in 1db
steps) from the default value.
