Istruzioni per l'uso
Accensione/spegnimento
Press and hold the "POWER" button on both the transmitter and receiver for approximately 3 seconds to turn them on or off.
Automatic Frequency Pairing
The C-977 system features automatic IR frequency pairing. Once both units are powered on, they should automatically connect. The RF light on the receiver will illuminate when a stable connection is established.

Selezione del canale
If you encounter interference or need to operate multiple wireless systems simultaneously, you can change the operating channel:
- Short press the "CH+" or "CH-" buttons on the transmitter to cycle through the available 16 UHF channels.
- Il ricevitore si sincronizzerà automaticamente con il nuovo canale.

Regolazione del volume
Use the "VOL+" and "VOL-" buttons on the transmitter to adjust the input volume level as needed.
Microphone Mode Selection (for XLR Transmitter)
The transmitter supports three microphone modes (0V, 5V, 48V) for compatibility with various microphone types:
- Long press the "CH+" button for 3 seconds to switch between 0V (for dynamic microphones), 5V (for condenser microphones requiring 5V bias), and 48V (for condenser microphones requiring phantom power).
- The display will show the currently selected mode. The system retains the last adjusted mode after restarting.

Risoluzione dei problemi
If you encounter any issues with your XTUGA C-977 system, refer to the following table for common problems and solutions.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessun suono / suono intermittente | Batteria scarica sul trasmettitore o sul ricevitore. | Recharge both units fully. |
| Nessun suono / suono intermittente | Units are not paired or on different channels. | Ensure both units are powered on and the RF light on the receiver is solid. If not, try changing channels on the transmitter to re-sync. |
| Nessun suono / suono intermittente | Distanza eccessiva o ostacoli. | Reduce distance between transmitter and receiver. Ensure a clear line of sight. |
| Nessun suono / suono intermittente | Incorrect microphone mode selected (for XLR). | Long press CH+ on transmitter to select the correct 0V/5V/48V mode for your microphone. |
| Hissing / Static Noise | Interferenze da altri dispositivi elettronici. | Move the receiver away from Wi-Fi routers, phones, TVs, or other wireless equipment. Try a different channel. |
| Hissing / Static Noise | Collegamenti allentati. | Check all cable connections (XLR, 6.35mm adapters) for secure fit. |
