Level".
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.
