How to charge the battery of the Snom C300?

Connect a USB-C cable to the speaker and to a power adapter (not included) of at least 5 V / 1.3 A. The power LED flashes white during charging. A full charge takes approximately 8 hours.

How to pair the speaker via Bluetooth?

Make sure the speaker is on. Press the Bluetooth button to enter pairing mode. The blue circular LED flashes quickly. Select "Snom C300" in your device's Bluetooth list. For NFC pairing, bring a compatible device close to the NFC area located on the top.

What to do if the speaker does not turn on?

Check that the battery is charged. Plug the speaker into a power outlet via USB-C. If the power LED is solid red, the battery is too low to start; wait a few minutes to charge. If the problem persists, perform a reset by pressing and holding the Reset button for 5 seconds, then press the Volume - button twice.

How to use the hands-free function for calls?

During an incoming call, press the Call button to answer. To end a call, press Call again. To mute the microphone, press the Mute button. Volume is adjusted with the Volume + and Volume - buttons.

How to reset the speaker to factory settings?

How to interpret the circular LEDs?

The 8 circular LEDs indicate several states: in purple, they show the battery charge level (1 to 8 LEDs). In blue, they show the volume (1 to 8 LEDs). In white, they indicate voice activity (the LED corresponding to the area where voice is detected lights up). In solid red, microphones are activated. In flashing red, battery low. Refer to the LED table in the manual for more details.

Can I use the Snom C300 speaker with a USB cable?

Yes, the speaker can be connected to a computer via USB-C (for power and audio streaming) or via USB-A (to charge other devices). The green USB LED indicates the connection is ready. However, for audio playback Bluetooth remains the primary wireless method.

What are the important safety precautions?

Use the speaker only indoors. Do not expose it to water, excessive heat, or explosive atmospheres. Maintain a distance of at least 20 cm between the speaker and your body (excluding hands) to comply with RF exposure limits. Do not attempt to open the device; the battery is built-in and not user-replaceable.

How to clean the Snom C300 speaker?

Use a soft, dry antistatic cloth. Never use water, solvents, or abrasive products, as they could damage the electronics or surface. For stubborn stains, lightly dampen the cloth with a little isopropyl alcohol.
