Hi,

Please note that this is an English forum.
However I have translated your enquiry.

To purchase a replacement PRM-20 remote we would recommend contacting a Promethean Reseller.
A full list of local resellers can be found on the below link:

If you have any issues please let me know.
Thanks,
Adam
