Gummy Alarm clock

To answer the question of whether the Karlsson Gummy alarm clock runs on batteries only, it is best to check the product specifications on the manufacturer's official website. Unfortunately, I do not have direct access to the internet to search the manufacturer's website in real time. However, I can suggest that alarm clocks often run on batteries, but some models may also have a mains power option. If you didn't find the information on the manufacturer's website the first time, it's worth trying again, making sure you search the technical specifications section or the product manual. If this information isn't available, it's worth looking at the product descriptions in online shops, which may include power supply details. Remember, the best source of information will always be the official manufacturer's documentation or user manual that comes with the product.

The alarm clock shows the time all the time.

To set the time manually, hold down the "TIME SET" button and then, while holding it down, set the hour with the "H" button and the minutes with the "M" button. Once the correct time has been set, release the "TIME SET" button, which will save the settings.

The alarm clock has a liquid crystal display and lights up in shades of grey.
