How to select "customize service available" for freq. band?

Hi,

I hope this is the right forum category, otherwise please feel free to move the topic.

Okay, I want to ask about this product seeedstudio.com/depot/2km-lo … Path=19_22
and this part “Working band: 433.92MHz (customize service available)”.

How can I customize it? I haven’t seen this option yet where I can buy this with a changed working band and what working bands I can select. Could your please give me a hind how I can do that?
I would prefer to have this set for 868 MHz but I would also be satisfied with 415 MHz, because I only need to sets for a up and down-link with this thing and without interferences.

Best regards,

Ronald
