41. RECEPTION
After connecting the power cord, antenna, micro-
phone, key device, etc., set controls and knobs by follow-
ing Table 1.
First, turn the POWER switch to ON. The pilot lamps
in the meter, sub-dial pointer, band switch and FIX CH
switch will all light up, indicating that the transceiver is
ready for operation. Because of solid-state design, the
transceiver can be put into operation immediately after the
POWER switch is ON.
Next, adjust the controls and knobs according to
TABLE 2.

The foregoing techniques are common to all modes
of operation. Each mode, however, calls for special tech-
niques of its own. Such special techniques will be dis-
cussed for each of the five modes.
CW Mode (How to use RIT)
With RIT switch turned off, position MAIN DIAL in
such a way that the incoming CW signal will beat at 900
Hz. Under this condition, you can ''zero in'' your operating
frequency to the frequency of incoming CW signal.
Similary, if the other party calls back with 900 Hz
beat tone in response to your call signal, it means that the
transceiver of the other party is in ''zero in'' status. Should
the other party call back with a beat tone off 900 Hz or
should you want to communicate with a beat frequency of
your choice, turn on RIT switch and adjust RIT knob to
obtain the desired beat.

easy guide.)
AF GAIN * Normally, this knob is set at
the extreme clockwise posi-
tion. When the signal is very
strong, turn it counterclock-
wise for suitable gain.
SQUELCH * This is used for FM mode of
operation. Turn the knob
clockwise so that noise at no-
signal time disappears. This
knob is normally set at a posi-
tion where noise just dis-
appears.
RIT * With the RIT switch ON, turn
the knob in either direction
and only the receive fre-
quency will be varied.
Refer to paragraph "'How to
Use RIT".
FM Mode
Set the MAIN dial for optimum reception. By setting
the METER switch to the CEN position, the meter func-
tions as a center meter (center freauency indicated). Turn
the MAIN dial so that the center meter indicates "0" while
receiving the other party's signal. In this way, the transmit
frequency will coincide with the receive frequency.
Next, set the METER switch to the S position and the
meter will indicate the strength of the incoming signal. If, in
this case, the meter pointer fluctuates in response to the
sound in the speaker, turn the MAIN dial a little (a few kHz)
in either direction until the meter indication is stabilized
(meter is stabilized if no fading exists).
Since the TS-600 is so designed that the IF circuit for
SSB forms a part of the '"'S'"' meter indication circuit for
FM, the ''S" provides logarithmic indications for FM waves
