2. Connect the Receiver: Push the selected adapter (iOS Lightning or USB-C) into the receiver, and then connect the receiver to your smartphone, tablet, computer, or other mobile devices. Alternatively, connect a camera or mixer to the receiver's 3.5mm TRS audio output using an adapter cable (e.g., 3.5mm TRS to 3.5mm TRS).
3. Power On: Press and hold the power buttons for 2 seconds to turn on the transmitter(s) and receiver.
4. Pairing: The transmitter(s) and receiver are paired by default. If they become disconnected, follow these steps: Press the receiver's M button until you reach the "Pair" menu page. Press and hold the M button, select "Yes?", and press and hold again to save settings. To make the transmitter(s) enter pairing state, press and hold its power button for 5 seconds in shutdown mode until its status indicator blinks blue rapidly. Transmitter(s) and receiver will pair within 10 seconds. The transmitter's information and status will be shown on the receiver's screen.

6. Set Output Mode: Set Mono, Stereo, or Safety Track mode on the receiver's menu as required.
7. Test Recording: It is recommended to record a sample and play it back to check if the audio level is acceptable before starting the main recording.
8. Enable Noise Cancellation: To improve recording in noisy environments, press the NR button on the transmitter(s) to enable noise cancellation.
9. Charge After Use: After recording, place the transmitter(s) and receiver back into the charging case for charging.

Notes:

• If a transmitter fails to pair, turn off the paired transmitter, then reconnect the unpaired transmitter and receiver.
• The 2.4GHz wireless frequency is widely used and susceptible to interference. Avoid obstacles like walls and buildings, and keep away from devices with 2.4GHz frequency (e.g., high-power Wi-Fi antennas, radios).

Onboard Recording

Press the transmitter's REC button to enable onboard recording, or activate "Auto Recording" mode so the transmitter starts recording automatically when switched on.

• The 8GB memory can store up to 15 hours of recording at 48kHz/ 24bit sampling rate.
• The file is automatically split after 30 minutes of recording for easier segment finding.
• Recording files are named in the format "DATE-TIME.WAV". Up to 999 files can be created.
• If the 8GB memory is full, the oldest file will be automatically overwritten by the latest file.

Hints:

• In this mode, the "mute" function does not affect onboard recording.
• Recording files cannot be read while onboard recording is active.
• Onboard recording is automatically disabled when the transmitter is placed in the charging case.

Troubleshooting

If you encounter problems, refer to this checklist before contacting technical support. If the problem persists, contact the dealer's after-sales service department.

No Sound or No Output:

• Ensure the receiver or adapter is well connected to your device. Remove the adapter and wipe charging contacts with a clean cloth.
• Check that mic gain or output volume is not set to minimum.
• Verify the unit is not muted.

Low/Loud/Distorted Sound:

• Adjust mic gain and output volume to a suitable level for the current environment.
• Enable noise cancellation in noisy environments for better recording.

Current Noise or Abnormal Noise:

• Ensure there is no interference near the unit. If noise persists after repositioning, contact customer service.

Limited Operating Range / Intermittent Sound:

• Ensure no interference between the transmitter(s) and receiver. If intermittent sound persists, contact customer service.

Receiver with Adapter Cannot Playback Output:

• Make sure your phone's speaker is disabled in the receiver's menu.

Howling Noise Occurs:
