To ensure audibility and clarity when transmitting with the
handheld microphone, always hold it as closely as possible
to the lips, then key the microphone and speak directly into
it. Avoid covering opening on back side of microphone for
optimum noise canceling.
STATIC DISCHARGERS
•. Static wicks (static dischargers) are installed at .various points
.throughout the airframe to reduce interference from precipitation
.static. Under s~me severe static conditions, loss of radio signals is
possible even with static dischargers installed. Whenever possible,
avoid known severe precipitation.; areas.b
prevent
loss...of
dependable radio signals.
If avoidance is impractical, minimize
airspeed and anticipate temporary loss ofiradio
signals while in
these areas. .
.' .
Static dischargers' lose their
effectiveness with .age,. and
therefore, should be checked periodically (at least at every annual
inspection)'byqualified avionics technicians, etc.
