Operating Instructions
1. Automatic Pairing (Flash Match)
The G-MARK X320FM system features automatic frequency synchronization. Once the receiver and microphones are powered on, they will automatically pair and lock to an available frequency. The receiver's display will show the synchronized frequency.
Figure 5: Illustrates the 'Flash Match' feature where the microphone and receiver automatically lock frequency immediately after power on.
2. Frequency Adjustment
If you experience interference, you can manually adjust the frequency on the handheld microphone. The receiver's frequency for that channel will automatically change to match the microphone's new frequency.
- Locate the AFH switch inside the microphone's battery compartment.
- Use the switch to select a different channel (A, B, C, or D).
- Observe the receiver's display; the frequency for the corresponding channel will update.
Video 3: Demonstrates frequency adjustment on the handheld microphone and how the receiver's frequency changes accordingly (1:24 - 1:46).
3. Volume Adjustment
Adjust the volume for each microphone channel directly on the receiver:
- For Channel A, use the 'UP/VOL' and 'DW/VOL' buttons on the left side of the receiver.
- For Channel B, use the 'UP/VOL' and 'DW/VOL' buttons on the right side of the receiver.
- The volume level will be displayed on the receiver's LCD screen.
Video 4: Shows how to adjust the volume using the UP/VOL and DW/VOL buttons on the receiver (1:47 - 1:58).
4. Frequency Lock/Unlock
To prevent accidental frequency changes, you can lock the receiver's frequency. To unlock, double-click the UP/VOL and DW/VOL buttons simultaneously on the desired channel.
Video 5: Demonstrates how to lock and unlock the receiver's frequency by double-clicking two keys simultaneously (1:15 - 1:23).

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphones | Microphone or receiver not powered on; low batteries; incorrect connection; mismatched frequency; receiver connected to AUX jack. | Ensure all devices are powered on. Check microphone batteries. Verify receiver is connected to the MIC input of your audio system. Check that microphone and receiver frequencies match. |
| Interference or poor sound quality | Other wireless devices operating on the same frequency; too far from receiver; obstacles blocking signal. | Adjust microphone frequency to an unused channel. Reduce distance between microphone and receiver. Ensure a clear line of sight between devices. |
| Low volume | Microphone volume too low; receiver volume too low; audio system volume too low. | Increase volume on the microphone, receiver, and your connected audio system. |
| Receiver display is locked | Frequency lock feature is active. | Double-click the UP/VOL and DW/VOL buttons simultaneously on the respective channel to unlock the frequency. |
