4. OPERATION@ RECEPTION¢ SQUELCH controlOF|When power and antenna connections are complete, set the controls and swit-ches as follows:2m FM TRANSCEIVER6.0093ot LILPOWER VOL ‘SoUrLenConnect microphone& O@ 7)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 thedisplay light to show the transceiver is operating.(2) As the POWER/VOL contro! is turned clockwise, either noise or a QSO isheard.(3) To eliminate the no-signal noise, use the SQUELCH control. For SQUELCHcontrol 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 squelchclockwise until the noise disappears and the BUSY indicator goes off (thresholdpoint).When a signal is received, the squelch will open, the BUSY indicator will lightand the speaker will operate.The SQUELCH control is also used for scan operation control. If the signal isweak or fades during mobile operation, readjust the squelch for constantreception@ TRANSMISSION© Transmitter precautions¢ HI/LOW power switchm_H= LOWTo 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 ONAIR indicator lights.1) The TM-201A antenna impedance is 50 ohms. Be sure to use only anantenna 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 transmitmode; the ON AIR indicator will light and the LED bar meter showstransmitter power. Recommended talk distance to the microphone is ap-proximately 5 cm.QSOinlocalscan beenjoyedwithlessinterferencetoothersandwithlesspower consumptionby reducingtheRF output power.Thisisaccomplished bydepressingtheHI/LOWswitch,which reducespowerfrom 25Wtoapprox.5W.
