3. Setup

3.1 Battery Installation and Charging

Each Solidcom C1 Pro headset operates on a rechargeable lithium battery. To install, locate the battery compartment on the headset and insert a charged battery, ensuring correct polarity. For charging, place the batteries into the provided charging case. A full charge typically takes 2.5 hours. A master headset provides approximately 6 hours of working time (when connected with 3 remote headsets), while remote headsets offer up to 10 hours.

3.2 Pairing Headsets

The Solidcom C1 Pro headsets are designed for easy pairing. To pair, press and hold the 'A' button on both the master and remote headsets simultaneously. The indicator light will flash rapidly, and the pairing connection should be successful within approximately 10 seconds. The system is backward compatible with Solidcom C1 headsets, allowing for flexible expansion of your communication setup.

4. Operating Instructions

4.1 Full-Duplex Communication and ENC

The Solidcom C1 Pro system enables full-duplex communication, meaning all connected users can speak and listen simultaneously without interruption. The integrated dual-mic Environmental Noise Cancellation (ENC) actively reduces ambient noise by up to 20 dB, ensuring crystal-clear audio transmission even in loud environments. This feature is crucial for maintaining effective communication in demanding production settings.

4.2 Push-to-Talk (PTT) Function

The Solidcom C1 Pro features a convenient Push-to-Talk (PTT) button. You can long-press the button to talk and release it to mute, similar to a walkie-talkie. Alternatively, a single press of the button will toggle the talk/mute state. The microphone boom can also be rotated up or down to quickly mute or unmute the microphone.

4.3 Wireless Range and Stability

The system operates in the 1.9GHz frequency band, providing a reliable and instant wireless audio transmission distance of up to 1,100ft (350m) in open line-of-sight (LOS) conditions. This extensive range ensures your team remains connected and can move freely across large and complex environments, such as film sets, event venues, or outdoor productions.

5. Care and Maintenance

5.1 Battery Management

To maximize battery life and performance, always use the provided charging case and USB-C cable. Avoid exposing batteries to extreme temperatures. If the system will not be used for an extended period, fully charge the batteries before storage and recharge them every three months to prevent deep discharge.

5.2 Cleaning

Gently wipe the headsets and charging case with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as these can damage the components. Ensure the microphone cushions and ear cushions are kept clean for optimal audio quality and hygiene.

5.3 Storage

Store the Solidcom C1 Pro system in its original storage case in a cool, dry place away from direct sunlight and excessive humidity. This protects the equipment from dust and physical damage when not in use.

6. Troubleshooting

If you encounter any issues with your Hollyland Solidcom C1 Pro system, please consider the following general troubleshooting steps:

• No Power: Ensure batteries are fully charged and correctly inserted. Check the charging case connection.
• No Audio/Intermittent Audio: Verify that headsets are properly paired. Check the wireless range and ensure no major obstructions are blocking the signal. Confirm microphone boom is in the 'talk' position and not muted.
• Poor Audio Quality/Noise: Ensure microphone cushions are properly installed. Check for excessive environmental noise that might exceed the ENC capabilities.
• Pairing Issues: Repeat the pairing process as described in Section 3.2. Ensure both headsets are in pairing mode simultaneously.
