5. Operating Instructions
5.1. Power On/Off
- To power on, press and hold the power button (usually the middle button) for approximately 2 seconds.
- To power off, press and hold the power button for approximately 2 seconds until the unit shuts down.
5.2. Setting Channel ID
For proper operation, the transmitter and all associated receivers must be set to the same Channel ID. Different groups operating simultaneously must use different Channel IDs to avoid interference.
- Ensure the earphone is plugged into the receiver and the microphone into the transmitter.
- Turn on the receiver or transmitter.
- Press and hold the middle button (power/menu button) for 2 seconds to enter the ID setting mode. The Channel ID on the display will flash.
- Use the left or right buttons to select the desired Channel ID (01-99).
- Press the middle button again to confirm the setting.
- Turn the unit off and then on again to finalize the setting process.
5.3. Volume Adjustment
- On the receiver, use the left and right buttons to adjust the volume to a comfortable listening level.
- The transmitter does not have a volume adjustment for its output; ensure the microphone is positioned correctly for optimal voice capture.
5.4. Multiple Group Operation
The system supports up to 40 groups working simultaneously by utilizing its 99 available frequency channels (195MHz-230MHz).
- Each group requires one transmitter and multiple receivers.
- Assign a unique Channel ID to each group's transmitter and its corresponding receivers.
- Ensure no two active groups are using the same Channel ID in close proximity to prevent interference.
6. Maintenance
6.1. Charging
- Always charge units using the provided charging case or USB cables.
