Press the SETUP knob to enter the channel setting mode.
Choose between GR (Group) or CH (Channel) by rotating the knob, then press it for confirmation.
Adjust the control knob to select the desired menu item (GR or CH).
Select the appropriate group or channel by rotating the knob.
Press the control knob to confirm the selected channel.
Finally, press the IR function to synchronize with the microphone.

Note: Settings are made while the system is in unlock status. Long press UNLOCK before making any adjustments.

Scan Available Channel Mode

This mode allows the system to automatically search for optimal frequencies:

Adjust the SETUP control knob and press the SCAN function to enter scan available frequency mode.
Use the control knob to select UP or DOWN to automatically scan for available frequencies until a desired frequency is found.

This function is convenient for users to quickly find available frequencies in different environments.

Volume Setting

Adjust the receiver's voice volume using the SETUP control knob. The volume level is visually indicated by a bar chart and a percentage.

3. SYNC window: Receives IR signal from the receiver's IR window for synchronization.
4. ON/OFF switch: Controls the microphone's power and mute functions.
5. Battery Sink: Compartment for inserting one 18500 lithium battery. Ensure correct polarity is observed.
6. Mic cap: Unscrew to change the battery.
7. USB Type-C socket: For charging the microphone (DC, 5 V).

Battery Insertion and Synchronization

To insert the battery, remove the battery cover and insert one 1x18500 Lithium battery, ensuring correct polarity. If the LCD does not light up after long-pressing the ON/OFF button for 3 seconds, check the battery polarity or if the battery is low. If the battery indicator is flashing, replace the battery. The microphone can only operate when synchronized with the receiver on the same frequency.

To synchronize the microphone with the receiver:

Unlock channel A or B on the receiver.
Press the IR button on the receiver.
Position the microphone's IR window in front of the receiver's IR window.
Verify that the same channel is indicated on both the microphone and receiver displays.

Note! The synchronization period is within 30 seconds. After switching ON, the microphone automatically enters the default mode and uses the last saved channel.

Handheld Microphone Using Technique

For optimal performance and sound quality:

Do not hold the microphone grille: Holding the grille can obstruct sound input and affect performance.
Mouth Distance: The distance between the microphone grille and the user's mouth should be less than 15cm.
Avoid placement in front of loudspeakers: Position the microphone to avoid feedback from loudspeakers.
Avoid holding the microphone on antenna position: Do not obstruct the microphone's antennas.

Diagrams illustrating correct and incorrect microphone handling: - Incorrect: Holding the microphone grille (marked with ❌). - Incorrect: Holding the microphone near the antenna position (marked with ❌).

7. Receiver Operation (Connections)

Antennas: Pull out antennas (11) and (12) so they are perpendicular to the receiver for optimal signal reception.
Power Connection: Connect the power adapter (12V 1A, positive central contact) to the DC input socket (16) on the receiver. Ensure the adapter is suitable for the receiver.
Audio Cables:
- Mix Output: Connect an audio cable (purchased separately) from the MIX.OUT socket (13) to the input of your mixer or amplifier.
- Balance Output: Connect a balance audio cable (provided) to the BALANCED OUT sockets (14/15) and then to the input of your mixer or amplifier.
USB Charge Cable: Connect the provided charge cable to the USB socket (17) and then to the handheld microphones for charging.

Notes:

Microphones can also be charged using other 5V chargers (e.g., smartphone chargers).
The microphone will not function while it is charging.
Ensure only rechargeable batteries are used; do not attempt to charge non-rechargeable batteries.

Powering On and Off:

Turn on the power button (1); the LCD display (5,7) will illuminate, indicating the receiver is in working status. Before turning off the receiver, it is recommended to turn the volume control knobs (2,10) to their minimum volume. Adjust the volume to your desired level after the next power-on.

8. IR SYNC and Installation Recommendations

Functions can be selected by adjusting the SETUP knob (2/10). For detailed function instructions, refer to the Receiver TFT display function guide.

Diagram illustrating the IR SYNC process: A handheld microphone is shown with its IR window aligned with the receiver's IR window. The text indicates "IR SYNC picture".

To initiate IR SYNC, long-press the IR button while the signal icon is flashing. Turn on the handheld microphone and place its IR window in front of the receiver's IR window. The signal icon will disappear once the devices are successfully connected by IR. The frequency displayed on the handheld microphone must match the frequency shown on the receiver displays.

Recommendations for Receiver Installation

Placement: The distance from the receiver to walls or the floor should be at least 1 meter. Failure to do so may decrease antenna efficiency and reduce the working distance.
Antenna Orientation: Pull out antennas vertically for better signal receiving.
