Hello, no, the alarm clock has only one alarm time, which can be activated or deactivated. With kind regards Your TFA Support

You can also use the alarm clock without batteries, in which case it only works with the mains adapter supplied. In this case, the display is permanently illuminated and the brightness can be set to one of three levels. Without the mains adapter and only with batteries, the display remains invisible and is only activated briefly by sound or touch. A permanent mains connection is therefore required for operation without batteries.

Permanent

The alarm clock features a touch function, allowing you to activate the display by touch. This feature is particularly useful when the device is operated with batteries, as the display remains invisible until activated by sound or touch.

*no alarm signal

I also tried to hide the display in mains operation, but I did not succeed either. If I remember correctly, this is only possible with battery operation according to the operating instructions.

I have three of these things in my house. All in mains operation. All of them have a minimum luminous display. But since I want to read the time at any time, I don't need the hand clapper function to activate it. Sorry, so I can't help you any further. A bit negative with these things is the automatic adjustment of the time, i.e. the installation without disturbing devices. PC screens, TV screens or bad reception... With two devices, time changeover is manual.

No, I don't think so. However, I have found out that the radio signal only works when the alarm clock is plugged in. It does not work when it is powered by batteries.

It has a DC 5V connection.

It is a bright alarm. Is not constant, but always makes beep beep

There is no overview of how to set different ringtones in the operating instructions. I assume that the ringtone cannot be changed ex works.

The clock usually resets itself at night for me. But a few weeks ago it committed treason and stopped at 1:45am. (Yes, I don't know how that works with a digital clock either). Anyway, it was a very strange night when the alarm on my mobile went off at the correct time.

It is all on the back together with the power connection

I have also noticed that the alarm clock loses the connection at night between 01:00 and 03:00 or probably tries to synchronise the time again. Since the clock only serves as an "eye-catcher" for the time, this is not a problem for me.

If the alarm clock is connected to the mains, yes. Then you can set whether the time, date and temperature are alternating or fixed. Battery-operated, the display switches off after a certain time and can be activated with a hand clap.

For sure it's not scary. Smooth or loud it may depend on your distance and perception, I'd say loud enough

The numbers are approx. 2cm high and a total of approx. 6cm wide.

No just on off the alarm

With a button on the back of the device. But I wouldn't buy it. Does not have a "snooze" function. Alarm turned off means turned off. Therefore, it is actually useless as an alarm clock. But I "slept through" returning it. TFA support did not respond to my question.

No, he didn't.
