Connecting LASKOMEX LM-8W Intercom: Matching 6 Wall Wires to Handset

I am looking for help in connecting the LASKOMEX LM-8W intercom. I lived in an apartment where the intercom worked - after renovation it was dismantled (I didn`t note which one...) 6 wires come out of the wall:
1. BLUE
2. BEIGE
3. ORANGE
4. BROWN
5. GREEN
6. GRAY

There are three wires coming out of the handset to the intercom - GREEN, WHITE, RED

Everything would be OK if it weren`t for the fact that only two screws marked + and - are visible in the intercom...... no more connections and there are as many as 6 wires!! Please for a hint.

Check, preferably with a meter, which wires have a constant voltage of approximately 7V.

I guess you bought the wrong uniphone. The one you show in the photo is for two-wire digital installations. The installed jumper shows that it is currently set to apartment number 4.
There is probably a 6-wire analog system in your block, because you write that the old uniphone worked, but you did not write down where it was connected. At least remember if all the cables were connected?

This is irrelevant. This connection is not interfered with.

The control panel system is the CD 2502 N system from Laskomex - the uniphone I have was already working - but the memory of the number of connected wires is volatile... - tomorrow I will try with a meter... "Experts" from the administration said that the uniphone was broken - and they paid PLN 80.. . hahaha ... but that`s just a side note...

Well, it`s actually a digital system. Do as Ircys wrote. Find two wires with voltage and connect them maintaining the correct polarity.

So what do you think? Will someone come and install a new uniphone for you, connect it and charge you PLN 40 for the whole thing? or maybe 35? 80 is still quite decent. I also had such "clients" often, and in 70% of cases they called again. Regards.

Well, if there were no anti-electronic people, what would be the need for conservation? Somehow, people still have problems - they call - they pay. Secondly, read what I wrote: PURCHASE, INSTALLATION, CHECKING, CONNECTING. What else can I deliver to someone else by bike? A multimeter for every intercom owner? He will probably go and buy it. The intercom is not working and what is anyone looking for the user manual for this intercom? Probably yes, even if the woman or man is 40-50 years old... I won`t mention that younger people are not more knowledgeable... Unfortunately, nothing is for free, and I value my time because of knowledge, as my colleague wrote earlier that in In this case, you don`t need much.
