After verifing the initial setup of controls and switches, proceed as follows:
(1) Turn the POWER/VOL control to turn on power. The indicators on the
display light to show the transceiver is operating.
(2) As the POWER/VOL contro! is turned clockwise, either noise or a QSO is
heard.
(3) To eliminate the no-signal noise, use the SQUELCH control. For SQUELCH
control operation, refer to next explanation.
(4) Tune to the desired frequency using MAIN DIAL.
To eliminate receiver noise at the no-signal condition, slowly adjust the squelch
clockwise until the noise disappears and the BUSY indicator goes off (threshold
point).
When a signal is received, the squelch will open, the BUSY indicator will light
and the speaker will operate.
The SQUELCH control is also used for scan operation control. If the signal is
weak or fades during mobile operation, readjust the squelch for constant
reception
@ TRANSMISSION
© Transmitter precautions
¢ HI/LOW power switch
m_H
= LOW
To transmit, first select frequency to be used and see whether it is busy or not.
If it is not busy, simply depress the mic PTT switch for transmission. The ON
AIR indicator lights.
1) The TM-201A antenna impedance is 50 ohms. Be sure to use only an
antenna of 50 ohms impedance.
2) Check the intended transmit frequency before operating to prevent in-
terference with other stations.
3) Pressing the microphone PTT switch places the transceiver in transmit
mode; the ON AIR indicator will light and the LED bar meter shows
transmitter power. Recommended talk distance to the microphone is ap-
proximately 5 cm.
