• Continue rotating to adjust the audio volume to a comfortable listening level.
• To power off, rotate the VOL/OFF knob counter-clockwise until it clicks.

6.2 Frequency and Channel Selection

• Use the FRQ knob to adjust the operating frequency.
• Use the CH knob to select the desired channel.
• The microphone's UP/DN buttons can also be used to change frequency or channel.
• Press the BAND button to cycle through the available frequency bands (A-I).

6.3 Mode Selection

• Press the MODE button to cycle through the available operating modes: FM, AM, USB (Upper Sideband), LSB (Lower Sideband), and PA (Public Address).

6.4 Squelch Adjustment
