CAUTION!
DO NOT transmit while an
SSG is connected to the
antenna connector directly.
CAUTION!
Firmly attach to the
multi-connector, but
do not overtighten.
The tests described in this section should be measured and adjusted with the above test equipment.
However, a radio tester can also be used for these adjustment procedures.
