C.FEATURES AND OPERATION
(1).BASIC OPERATION
SWITCHING POWER ON/OFF
1. Turn the {POWER] switch clockwise to turn ON the transceiver
yA music tone sounds.
2. To turn OFF the transceiver, turn the [POWER] switch counter clockwise
again.
ADJUSTING VOLUME
Turn the [VOLUME] control clockwise to increase the audio output level and
counterclockwise to decrease the output level.
yIf you want to check whether there is interference on this channel, please
press (Moin) button andd turn (VOL), then you will hear the squelch or
interference sounds.

TC-245S คูมือการใชเครื่อง
ADJUSTING SQUELCH
The purpose of the Squelch is to mute the speaker when no signals are present.
With the squelch level correctly set, you will hear sound only while actually
receiving signals. The higher the selected squelch level, the stronger the signals
must be, to receive. The appropriate sqrelch level depends on the ambient RF
noise conditions.
a, Press [F ] , [1SQL].
yThe current squelch level appears.
b, Use the [ ] , [ ] key to select the squelch level from 0 to 9.
ySelect just the level at which the background noise is eliminated when no
signal is present.
yThe larger the level number you select, the stronger the signals you need to
receive to hear.
c, Press any key other than [LAMP] and[MONI] to complete the setting.
SELECTING FREQUENCY
Use [ ] key to increase the frequency,and [ ].to decrease the frequency.
yIf you cannot select a particular frequency, the frequency step size needs to be
changed.See “CHANGING FREQUENCY STEP SIZE” .
yYou can also select frequencies with the numeric keys.
TRANSMITTING
a, To transmit ,hold the transceiver approximately 5 cm ( 2 inches) from your
mouth, then press and hold the [PTT] switch and speak into the microphone in your
normal tone of voice.
yThe status LED on the top panel lights red and bar-graph meter appears
b, When you finish speaking. Release the [PTT] switch.
(2) SCAN
Scan is useful function for hands-off monitoring of your favorite channels. By
becoming comfortable with all types of Scan, you will increase your operating
efficiency.
SCAN RESUME METHOD
Before using Scan, it’s necessary to decide under what condition you want your
transceiver to continue scanning after detecting and stopping for a signal. You can
choose one of the following modes. The default is Time-Operated mode.
yTime-Operated Mode (Default)
Your transceiver stops scanning when detecting a signal, remains there for
approximately 5 seconds, and then continues to scan even if the signal is still present.
yCarrier-Operated Mode
Your transceiver stops scanning when detecting a signal and remains on the same
channel until the signal drops out. There is a 2 seconds delay between signal drop-out
and scan resumption to allow time for any responding stations to begin transmitting.
Note: Pressing and holding [MONI] causes the transceiver to stop scanning; releasing
[MONI] causes it resume scanning.

TC-245S คูมือการใชเครื่อง

yScan starts with the channel last recalled.
yTo reverse the scan direction, use [ ] (upward scan)or [ ] (downward scan).
2. To quit Channel Scan, press any key other than[LAMP],[MONI].
(3) CTCSS
You may sometimes want to hear calls from only specific persons or groups. The
Continuous Tone Coded Squelch System(CTCSS) allows you to ignore (not hear)
unwanted calls from other persons who are using the same frequency. Simply select the
same CTCSS tone as selected by the other persons in your group. A CTCSS tone is
subaudible tone and is selectable from among the 50 tone frequencies.
Note: CTCSS does not cause your conversation to be private.If only relieves you of
listening to unwanted conversation.
USING CTCSS
a. Select the desired channel number.
b. Press[F ],[6CTC] to switch the CTCSS function ON(or OFF).
