5.3. Channel Synchronization (Automatic)

To ensure all receivers are on the same channel as the transmitter, follow these steps for automatic synchronization:

1. Turn on the transmitter by pressing the power button for 1 second.
2. Simultaneously press and hold the left and right channel selection buttons on the transmitter until the channel ID numbers start flashing. This indicates the transmitter is in channel setting mode.
3. Use the left or right buttons to select your desired channel ID (e.g., 9999).
4. Press and hold the 'M' (middle) button on the transmitter for 5 seconds until all four digits of the channel ID start flashing. The transmitter is now in wireless channel matching mode.
5. Turn on each receiver one by one and place it close to the transmitter (within 1 meter). The receiver's channel ID will automatically sync with the transmitter's channel ID.
6. Once all receivers are synced, click the 'M' button on the transmitter again to exit sync mode and return to normal speaking mode. The LCD screen will show 'M' and the channel digits will stop flashing.

5.4. Channel Synchronization (Manual)

If automatic synchronization is not preferred or encounters issues, channels can be set manually:

1. 송신기를 켜세요.

4. Once the channel is set, press and hold the 'M' button for 5 seconds to confirm and exit channel setting mode.
5. For each receiver, turn it on. Press and hold the '+' and '-' volume buttons simultaneously until the channel ID starts flashing.
6. Use the '+' and '-' buttons to manually set the receiver's channel ID to match the transmitter's channel ID.
7. Press the power button on the receiver to confirm the channel setting.
