3. Betjeningsvejledning
3.1. Tænd/sluk
- Mikrofoner: Locate the power switch on the microphone handle. Slide it to the 'ON' position to power on. The indicator light will illuminate. Slide to 'OFF' to power off.
- Modtager: The receiver powers on automatically when plugged into a USB power source. Unplug to power off.
3.2. Automatic Frequency Pairing
The Alvoxcon system is designed for ease of use. Upon powering on both the microphones and the receiver, they will automatically search for and pair with each other on an available frequency within the 902-928Mhz range. No manual frequency selection is typically required.
3.3. Overvågning i realtid
The USB receiver includes an 'AUX Out' port, allowing you to connect headphones for real-time audio monitoring. This is useful for ensuring clear sound capture during recording or live streaming.
3.4. Using Dual Microphones Simultaneously
The system supports simultaneous use of both handheld microphones. Each microphone will operate on a separate channel, allowing two speakers to be active at the same time. This is particularly useful for interviews, presentations, or duets.

4. Vedligeholdelse
4.1. Rensning
Wipe the microphones and receiver with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as this may damage the device.
4.2. Opbevaring
Store the microphone system in a cool, dry place away from direct sunlight and extreme temperatures. When not in use for extended periods, ensure the batteries are partially charged (around 50%) to prolong battery life.
4.3. Batteripleje
To maximize battery lifespan, avoid fully discharging the batteries frequently. Recharge them regularly, even if not completely depleted. If the device will not be used for a long time, charge it every 3-6 months.
5. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen lydudgang | Microphone/receiver not powered on; incorrect connection; low battery; volume too low. | Ensure all devices are powered on. Check USB and AUX cable connections. Recharge batteries. Increase volume on connected device/speaker. |
| Interference/Poor sound quality | Obstructions between mic and receiver; strong Wi-Fi/Bluetooth signals nearby; microphone too far/too close. | Ensure clear line of sight. Move away from other wireless devices. Adjust microphone distance from mouth (e.g., if clipping occurs, move slightly further away). The system auto-pairs to optimal frequencies. |
| Mikrofonen parres ikke | Microphone/receiver not powered on; out of range. | Ensure both devices are powered on. Bring microphone closer to the receiver. |
