5.1. 전원 켜기 / 끄기
Press and hold the power button (usually marked with a power symbol) on the radio's front panel until the display illuminates. To power off, press and hold the same button until the display turns off.
5.2. 볼륨 조절
Rotate the volume knob (typically labeled 'VOL' or with a speaker icon) clockwise to increase the audio output and counter-clockwise to decrease it. Adjust to a comfortable listening level.
5.3. 채널 선택
Use the channel selector knob or the UP/DOWN buttons (if available) to cycle through the programmed channels. The selected channel number or name will be displayed on the screen.
5.4. 송신 및 수신
- 전수: 라디오 전원이 켜져 있고 볼륨이 적절하게 조절되어 있는지 확인하십시오. 라디오는 선택한 채널의 신호를 자동으로 수신합니다.
- 전송 : Before transmitting, listen to ensure the channel is clear. Press and hold the PTT (Push-To-Talk) button on the microphone. Speak clearly into the microphone. Release the PTT button to return to receive mode.
5.5. 프로그래밍 가능 버튼 사용

5.6. Signaling Functions (2-Tone, 5-Tone, CTCSS, DTCS)
The radio supports various signaling formats. When a channel is programmed with 2-Tone, 5-Tone, CTCSS (Continuous Tone-Coded Squelch System), or DTCS (Digital Tone-Coded Squelch), the radio will only open its squelch and allow audio through when it receives a signal containing the correct tone or code. This helps to filter out unwanted communications. Up to ten 2-tone and eight 5-tone codes can be decoded per channel.
