How to use

Place the TFA Soluna on a stable surface near the bedside or on a desk and connect it to a suitable power source. Set the current time and date following the device controls, select the desired language for weekday display, and programme an alarm time. Choose the wake‑up method using light, sound or a combination, and adjust snooze duration if required. Set preferred backlight colour or automatic colour‑change program, and modify display brightness or enable automatic dimming to avoid nighttime disturbance. Connect a mobile device to the USB output to charge overnight if needed.

Usage recommendations

Use the gradual brightening light in combination with a soft alarm tone to support natural wake‑up. For bedroom use enable a lower display brightness or automatic dimming to reduce light disturbance. Use the room temperature and humidity readouts to assess comfort; green light indication for ideal conditions is useful as a quick visual cue. When travelling, keep the compact dimensions and USB charging function in mind to minimise the number of chargers you carry.
