4. Montážní návod
This kit involves soldering, including Surface Mount Device (SMD) components. It is recommended for individuals with prior soldering experience or those looking to develop advanced soldering skills. Refer to the detailed, full-color printed user manual included in your package for step-by-step assembly instructions.
4.1 Important Considerations for SMD Soldering
- Trpělivost je klíčová: SMD components are small and require precision.
- Nástroje: A fine-tip soldering iron, thin solder wire, flux, tweezers, and a magnifying glass or microscope are highly recommended.
- Technika: Be mindful of bridging pins. For complex SMD chips, techniques like drag soldering or using solder paste with a hot air station may be beneficial.

5. Návod k obsluze
Once assembled and powered via the Micro USB port, the clock will display the current time or switch to spectrum mode if sound is detected. Use the integrated buttons to navigate and adjust settings.
5.1 Základní obsluha
- Zapnutí: Connect the Micro USB cable to a 5V DC power source.
- Automatický režim: The clock will automatically display the music spectrum when sound is present and revert to time display when silent.
5.2 Nastavení funkcí
The device typically uses one or two buttons for all settings. Refer to your printed manual for exact button functions. Generally, a short press cycles through options, and a long press enters/exits a setting mode.
- Nastavení přístupu: Press and hold the 'SET' button (or equivalent) for approximately one second.
- Upravit hodnoty: Lightly press the button once to change the value or cycle through options.
- Nastavení procházení: Press and hold the button again to move to the next setting screen.
