CESSNA
MODEL R,182
the
pilot
wants
only
ADF audio, for station identification
orother reasons,
the
AUTO
selectonswitch
(if
in use) and all
other audio selector switches
should
be
in the OFF
position.
If simultaneousADF
and NAVICOM audio
(
is
acceptable
to
the
pilot,
no change in the
existing
switch
positions
is
\
required. Place the
ADF
1
or
2
switch
in
eitherthe
SPEAKER,
or
PHONE
position
and
adjust
radio volume as desired.
NOTE
If
the NAV
I
COM audio selector switch
corresponding to
the selected
transmitter is in the PHONE
position
with the
AUTO selector
switch
in
the SPEAKER
position,
all audio
selector
switches
placed
in the PHONE
position
will
automa,tically
be connected to both the
airplane speaker
and any
headsets
in
use.
MICROPHONE,H
EADSET
The microphone-headset
combination consists
of the microphone and
headset
combined
in a single unit and a microphone
keying
switch located
on the left side
of the
pilot's
control
wheel.
The
microphone-headset
permits
the
pilot
to conduct radio communications
without
interrupting
other
control operations
to handle
a hand-held
microphone.
Also,
pas-
sengers need not
listen to all communications.
The
microplrone and
headset
jacks
are
located near the lowerleft
corner of the
instrument
panel.
STATIC
DISCHARGERS
If frequent
IFR
flights are
planned,
installation
of
wick-type
static
dischargers
is recommended
to improve radio
communications during
flight through
dust
or
va,rious forms of
precipitation
(rain,
snow or
ice
crystals). Under
these
conditions, the build-up and
discharge
of static
electricity
fromthe
trailing
edges of the wings, rudder,
elevator,
propeller
tips,
and
radio antennas
can
result in loss
of usable
radio
si.gnals on'all
communications
and
navigation radio equipment.'UsuallJz the ADF. is first
to be affected
and
VFIF
communication equipment is
the
lastto
be affected.
Installation
of static
dischargers reduces interference from
precipita-
tion
static,
but it
is
possible
tO'encounter severe
preeipitation
static
conditions
which
might cauSe
the
loss
of radio signals, even with static
dischargers
installed.
Whenever
possible,
avoid known
severe)precipita-
tion areas
to
prevent loss of dependable radio
signals. If avoidance
is
impractical,
minimize
airspeed and anticipate temporary loss of radio
signals
while in
these
areas.
