How to do a factory reset for DECT Aastra DT432?

[dll2003]

Hi guys!

We have some DECT terminals DT432.
These handsets have registrations in several DECT systems, as well as other information that is no longer needed there.
These DECT systems themselves no longer exist.
I need to register them in the new DEST system.

Is there any tricky combination to factory reset these handsets?

BR, Dmitriy.

Hello klobo1970!

Unfortunately handsets DT432 don't have the Call Time screen
I found only the Call List menu, but the sequence of pressing the characters > * < < * < doesn't lead to the appearance of Admin menu on screen handsets.
I still could not find information on resetting this model handsets to factory settings.
