5.1 Transmitter (TX) Operation

• Microphone Input: You can use the built-in microphone or connect the DK3G lavalier to the 'MIC IN' port.
• Gain Control: Use the '+' and '-' buttons on the TX to adjust the microphone input gain. Monitor the audio levels on the RX receiver to prevent clipping.
• Mute Function: Short press the power button on the TX to mute or unmute the microphone. The screen will indicate the mute status.
• Low Cut Filter: The TX features a 4-stage low-cut filter to reduce unwanted low-frequency noise (e.g., wind, rumble). Access this setting via the TX menu.
• Auto Gain: The TX can automatically adjust gain levels for optimal audio. This feature can be enabled or disabled in the TX menu.

5.2 Receiver (RX) Operation

• Output Mode (Mono/Stereo): Use the RX menu to switch between Mono and Stereo output modes. In Mono, both TX inputs are mixed to both left and right channels. In Stereo, each TX input is sent to a separate channel (TX1 to Left, TX2 to Right).

• Level Meters: The RX screen displays audio level meters for both TX units, allowing you to visually monitor input levels.
• Automatic Brightness: The vivid color LCD screens on both TX and RX units feature automatic brightness adjustment for optimal visibility in various lighting conditions.
• Channel Switching: The system automatically switches channels to avoid static and dropouts, ensuring a stable connection.
