@ ANT (ANTENNA) CONNECTOR
This UHF connector should be attached to a suitable anten-
na for transmitting and receiving. The antenna cable should
be of a 50-ohm unbalanced type, terminated in a PL-259
plug.
@ GND (GROUND) TERMINAL
The TS-120S(V) should be grounded through this terminal
to avoid the possibility of TVI and BCI. Use as short, and
heavy a lead as possible.
@ CW KEY JACK
For CW operation, connect your key to this terminal using a
two conductor phone plug and shielded cable.
@ SPEAKER (EXTERNAL SPEAKER) JACK
An external speaker of 4 ~ 16 ohms impedance (such as
the SP-120) can be connected here. This will disable the in-
ternal speaker.

© REMOTE CONNECTOR
This is used for interconnecting a linear amplifier or other
equipment. For connection, refer to the illustration below,
fig. 3-3.
© EXT VFO (EXTERNAL VFO) CONNECTOR
This is for connection of an external VFO-120. (Note: the
VFO-520 and VFO-820 cannot be used, since their
operating frequency is incorrect.)
@ DC POWER CONNECTOR
This is used to connect the DC power supply.
REFERENCE FREQUENCY ADJUSTMENT
For PLL reference oscillator adjustment. Use WWYV signal
for calibration.
@ COOLING FAN
The cooling fan operates when the heat-sink temperature
rises.
