Thats basically what 'Smart animals' is. Even birds have this. Still doesn't mean birds can understand what radio is WHILE NOT HEARING IT AND NOT SEEING IT and how are they sopposed to link radio with Tcomms tower, hmm? How can they KNOW what SD is? There is a big difference between intelligent and omniscient.
Yeah, mistos got the right idea. I mean, we're all just peeps that play the game. To get a super serious lore based answer youre gonna have to pester somebody official. Maybe that penguin person that runs the wiki? But its not that tricky to think up one yourself.
Real low effort explaination involves the intragalactic hivemind. If you check out the
timeline youll see that this is not the first time xenos have encountered humans or marines. So the xenos know all this because as a species, this enemy is not new to them. CAS lasers, OBs, defibs, theyve seen it all before and that knowledge has been embedded in their genetic memeory(leaving that typo). Much like their knowledge of the predators, its something theyre born with or they just get an update from the near omniscient Queen Mother.
A slighty more specific take on it that could appeal to your viewpoints better is that Xenomorphs have much greater senses than humans. Sure, theyre just smart animals but the range of the electromagnetic spectrum they can detect is much greater, broader, maybe even contiguous. Unlike humans that can only detect three narrow bandwidths of electromagnetic radiation, Xenomorphs could see and understand whole swaths of it. Radio is just a different bandwidth of light, so perhaps the headsets and communication towers glow like bright pulsing beacons to them. Power units would stand out and seemingly flicker as the currents of electricity change inside. It wouldnt be too much of a stretch for them to associate the same pulsing patterns of the marine headset units with the very same pulses of the telecommunication equipment.
Ultimately the burden of justification falls to you though. Its not anybody's responsibity to force the game to make sense for you. The xenos just represent the hostile other, the true alien. Thematically they're the embodiment of some of the worst human experiences:
rape, mutilation, forced pregnancy. Closer to a supernatural entity or a force of nature, any attempt to logically define or understand them serves to undermine that and reduces the impact they can have. So like, dont feel the need to do that. They're scary space bugs, let em do scary things. The more off balance and upsetting they can get you the better. Its what they were made for.
