Receiver Display

The receiver display provides the following information:

• RF: Indicates signal intensity. Longer color length means stronger signal.
• AF: Indicates audio level. Longer color length means stronger signal.
• GR/CH: Displays the current group (GR) and channel (CH) number.
• SCAN: Auto scan function to search for available frequencies.
• 46%: Indicates current volume level (0%-100%).
• Lock status: Buttons are ineffectual.
• Mute status: Receiver is muted.
• IR icon: Flashing indicates SYNC signal transmission.
• Battery icon: Indicates handheld microphone battery status during charging.

Receiver Operation

• Pull out antennas (11, 12) and position them perpendicularly to the receiver.
• Connect the power adapter (12V 1A) to the DC input (16). Ensure the adapter is suitable for the receiver.
• Audio Connections:
  • Mix output (13) connects to mixer/amplifier INPUT via audio cable.
  • Balance outputs (14, 15) connect to mixer/amplifier INPUT via balanced audio cables.
• USB Charge Cable: Connect the attached USB charge cable to the USB socket (17) to charge the handheld microphones. Note: Other 5V chargers (like smartphone chargers) can also be used. The microphone does not operate during charging, and non-rechargeable batteries should not be charged.
• Turn on the power button (1). The LCD display (5, 7) will illuminate. To turn off the receiver, turn the volume control knob (2, 10) to minimum volume before powering off.

Handheld Microphone Operation

Synchronization with Receiver:

• Insert a 1x18500 Lithium battery into the microphone's battery sink (5) with correct polarity. If the LCD does not light up, check battery polarity or power. A flashing battery indicator suggests a low battery. The microphone operates only on the same frequency as the receiver.
• To synchronize: Unlock the receiver (A or B), press the IR button on the receiver, and place the microphone's IR window in front of the receiver's IR window. The frequency should match on both devices. Synchronization is typically within 30 seconds.
• After power-on, the microphone defaults to the last saved channel.

Proper Microphone Handling:

• Do not hold the microphone grille.
• Avoid holding the microphone on the antenna position.
• Maintain a distance of less than 15cm between the microphone grille and mouth for optimal pickup.
• Avoid placing the microphone in front of loudspeakers.
• Do not use two microphones together.

Microphone Display Information:

• GROUP/CHANNEL: Indicates the working group and channel.
• MUTE: Indicates mute status.
• Frequency: Displays the current using frequency (e.g., 902.5 MHz).
• Battery Status: Flashing indicates low battery power.
• HI/LO: Indicates high or low transmission power.

Channel Setting Mode

To adjust settings:

• Long press the UNLOCK button on the receiver to unlock the system.
• Select menu icons by rotating the SETUP knob.
• Press the SETUP knob to enter channel setting mode.
• Rotate the knob to choose the desired group (GR) or channel (CH).
• Press the knob to confirm the selection.
• Press the IR function button for synchronization with the microphone.

Scan Available Channel Mode:

• Adjust the SETUP control knob and press the SCAN function to enter scan mode.
• Rotate the control knob to select UP or DOWN to automatically scan for an available frequency. This function helps find a suitable frequency quickly.

Volume Setting:

• Rotate the SETUP control knob to adjust the receiver's volume. The volume level is visually indicated by a bar chart and a percentage.
