Whilst mostly the hams are expected to be responsible and adequately assess/maintain their stations as part of their tech licensed status, there’s really no excuse for any radio operator/user not doing at least a cursory assessment.
Whilst most categories of users aren’t required to, a bit of effort to help ensure you’re well within any applicable EMC requirements and your setup is operationally safe goes a long way.
Even if you just get help from a ham to do a cursory assessment of the current state of play, you can document in any required or voluntary risk assessment etc as having undertaken whatever tests were done, which may help your case if you’re ever unjustly accused of causing EM/RF issues or other safety question marks over a self installation. It’s well known in the ham world that if your setup ever gets spot checked or as a result of a formal complaint, whoever investigates will certainly expect to see logs of your tests/assessment efforts and the more frequently the better.
So I’m not saying that non-hams should do as we do, but at least consider the wisdom of being ahead of the game and know you voluntarily took responsibility.
In the UK, most categories of users have near zero awareness they are actually responsible for their stations, use and conduct - it’s usually those of us with something to lose that’s either a personal disaster and reflection of our competence or those who depend on their kit for work or essential support duty ”as required” who bother. I’d imagine a similar, but maybe proportional different, state of play exists outside of the EU and UK.
So just consider going the extra step, after all once it’s done a few times, it becomes routine and barely bothers you about how little or much time your ability level of assessment takes.
Remember, just in case those reading this are in the license-free/exempt zone of licensing, how you are licensed or permitted to operate doesn’t remove or exempt you from due caution and precautionary practises - it’s actually buried within the stuff you never read where it mentions you share the same basic responsibility common to all wireless operators.
Even back in my dark murky past bit that covered CB days, I put nothing on air without assessing it’s EM/RF state first - being the son of a ham operator ensured I had the means, but even in different circumstances as the time, I’d have still made an effort and regardless, kept a log of contacts and any testing/assessments I or my father undertook on my behalf - not out of explicitly recognized requirement but because it both made sense and was loosely required in practice.
So just think responsibility, and you’ll realise that it’s a small price for a bit of reassurance.
