GENERAL DESCRIPTION
Make the interconnections described in Section
1.3 with the transceiver and
VFO off.
Set the TS-820's
FUNCTION
switch to VFO for normal transceive
operation.
The
function
of each
VFO
is controlled
by the FUNCTION
switch
on
the
VFO-820
and the FUNCTION
switch on the TS-820.
Tables 1 and 2 show
what
possible
operating
and
calibrating
possibilities
are
available.
The
light-emitting-diode indicators on the VFO and on the transceiver show which
circuit is controlling operation.

CALIBRATION AND DIAL READING
See the TS-820's operating manual for information on reading the operating
frequency.
Table 2 shows the possible calibrating functions.
The VFO-820 is
calibrated in the same
manner as the TS-820.
3.3.
RIT (RECEIVER INCREMENTAL TUNING)
See the RIT section in the TS-820 manual for a full description of RIT. The RIT
control on the VFO allows receiver tuning when the VFO-820 is controlling the
receive function.
The RIT circuit must be turned on by the RIT switch.
The RIT
indicator will show when the circuit is turned on.
