Landline phone problem

I have a Carrera Classic Plus landline phone that can either be used without a PSU (limited functionality) or with one (full functionality). However, whenever the PSU is plugged into the phone, there is an unpleasant level of static noise, making the phone impractical to use. Whilst I can return the phone, I got it at a good price and would prefer not to if it can be helped. What might the problem be, and what can I do?--Leon (talk) 14:35, 14 October 2017 (UTC)[reply]

Have you talked to the one who sold it to you? There might be a good reason you got it cheap. ←Baseball Bugs ^{What's up, Doc?} carrots→ 15:04, 14 October 2017 (UTC)[reply]

You might try to exchange it rather than return it. Most retailers prefer exchanges over returns, as that way they don't have to give back any money. StuRat (talk) 15:45, 14 October 2017 (UTC)[reply]

In principle, a power conditioner may help. In practice, it may cost more than the phone, and not help much or at all. SemanticMantis (talk) 19:48, 14 October 2017 (UTC)[reply]

Does the phone have batteries in addition to the PSU? If so, do you have them installed? In some situations with some devices, the batteries act sort of like a noise filter to suppress noise on the power line. -Arch dude (talk) 20:51, 14 October 2017 (UTC)[reply]

Star trooper man, this is not an encyclopedia related enquiry. Please refer to the product instruction manual or the original vendor. Kudpung กุดผึ้ง (talk) 10:47, 28 October 2017 (UTC)[reply]
