verI.
the RIT circuit is ON
By turning the RIT knob. the receive
frequency of VFO can be changed by :t3 kHz and the fre-
quency of fixed channel by :t 150 Hz without changing the
transmit frequency.
@
H. SW (HEATER) SWITCH
This switch turns the heater circuits of the three transmitting
tubes on and off. The heaters would normally be turned to
OFF to reduce power consumption
in mobile or portable re-
ceiving.
@
BAND SWITCH
This 11-position
switch selects all the necessary circuits to
tune the transceiver to the desired 500 kHz band.
~~
POWER SWITCH
The POWER switch turns all the power on and off in
TS-8205.

FUNCTION
SWITCH,
,
This
7 -position
rotary
switch
selects
one
of the
following
transceive functions.
This
position
allows
calibration
of the 1"5-8205'5
internal
VFO to one of the transceiver's
fixed
fre-
quency
channels
(if an optional
fixed
channel
cry-
stal is installed),
With the switch
in this position
a
signal
is generated
at the selected
fixed
channel
frequency
and the main tuning
knob can be tuned
to zero
beat the
calibrating
signal,

RIT KNOB
This knob is used to change
receive
frequency
when the AIT
circuit
is in operation
Set the
center
position
(0) of the
AIT knob
to the
AIT -OFF.
@
IF SHIFT
KNOB
By using this knob during reception. the center frequency of
the IF crystal filter can be shifted by :t 17 kHz. facilitating
the adjustment of the tonal quality of receive signal or elimi-
nating radio interference
from nearby frequencies.
For nor-
mal operation. this knob should be set to the center position
(click is heard).
This position alloWs calibration
of the VFO-820
(remote VFO) to the transceiver's
operating
fre-
quency.
With the switch
in this position.
the
transceiver generates a calibrating
signal and the
VFO-820
can be tuned to zero-beat the calibra-
ting signal.

MIC GAIN
KNOB
This knob is used for adjustment of the gain of MIC amplifier
during sse operation.
Adjust so that the meter pointer does
not deflect beyond the ALC lone.
With the switch in this position. the transceiver's
calibrator
circuit generates
a marker signal
at
every 25 kHz for normal calibration
of the internal
VFO.
CAL-
25 kHz:
The switch
is kept in this position
for normal
transceive operation.
VFO:
@
CAR (CARRIER)
LEVEL KNOB
Used to adjust carrier level during CW operation. Adjust so
that the meter does not deflect beyond the ALC lond.
With the switch in this position. the TS.820S's
in-
ternal VFO controls the receive function and the
internal fixed channel oscillator controls the trans-
mit function (if fixed channel crystals are installed
in the oscillator).
VFO.R
@
AF GAIN
KNOB
This knob adjusts the gain of the receiving audio amplifier
The audio volume of the received signal increases as the
control is turned clockwise.
With the switch in this position, the TS-820S's
in-
ternal VFO controls the transmit function and the
built-in fixed channel oscillator
controls
the re-
ceive function (if fixed channel crystals are instal-
led in the oscillator)
The VFO.R and FIX.R allow
cross-channel
operation without an external VFO.
FIXR:
@
RF GAIN
KNOB
This control adjusts the gain of the receiver sections
RF am-
plifier.
Turn the knob fully clockwise for maximum gain and
for a correct S-meter reading
Turn the control counter--
clockwise to reduce the gain.

FIX CH (FIXED
CHANNEL)
SELECT SWITCH
This
four-position
rotary
switch
selects
between
four
diffe-
rent fixed
frequency
channels

With the switch in this position. the IS-820S's
fixed channel oscillator controls the transmit and
receive function
of the transceiver
