The settings for the two alarm times A and B can be made individually. This means that the time, alarm tone, radio station and volume can be set freely for both and are independent of the selected volume of the radio. When the alarm clock switches on, the volume slowly increases to the desired level. :-)
No, the radio cannot be used with the backup battery (CR2032) in the event of a power failure. The back-up battery is only used to store the time and the alarm, but the radio itself will not work.
According to chatGPT
❓ Code "ErrU56
This code does not appear in the official Sony manual.
It may indicate:
1. display bug or incorrect display of another message.
2. low or empty back-up battery ("" icon normally provided).
3 Software problem or fault.
⸻
🔧 Steps to try
1. simple reset:
- Disconnect the alarm clock from the mains.
- Remove the CR2032 battery.
- Wait at least 30 seconds.
- Replace the battery and reconnect.
2 Replace the CR2032 battery with a new one, even if the old one seems to be fine.
3) Factory reset (via the alarm clock menu) to clear any software errors.
4) Observe when ErrU56 appears: at start-up, during a setting, or after a power cut.
5. contact Sony support if the message recurs after these steps.
Yes, it works today too, it will be plus. The big fault with this device is that it only changes from summer to winter time when the radio is switched on. So the time setting only works when you have already overslept.
No, in this price range, a new purchase might be cheaper.
With mine, the display "changed" after a short time, i.e. it became dimmer at all levels and/or the background 'lit up'. Disconnecting it from the power supply (unplugging it and plugging it back in again after a while) solved the problem for a short time, but it reappeared later.
Hello
The light intensity can be adjusted by pressing the snooze button. It can even be switched off and it lights up slightly when the alarm clock rings.
