How do I switch the input source on my Grace Digital GDI-BTAR502 to play music from a connected Bluetooth device?

I live in an older apartment building with through-the-wall AC units, and my Carrier 52SEC514 was making a weird rattling noise last summer. I was worried something major was broken internally, but I found the product data sheet for the series online which helped me understand the unit's construction better. Looking at the specs for my specific model on https://carrier.manymanuals.com/split-system-air-conditioners/52s-series/user-manual-28166 [nofollow] carrier 52sec514 manual, I realized the noise was probably coming from the slinger ring on the condenser fan, which is mentioned in the "Product Features" section. That ring can sometimes get debris caught in it or just vibrate if it's loose. I carefully cleaned around it through the outdoor grille and tightened a couple of accessible screws on the shroud, and the rattle disappeared. It also helped me confirm the correct amperage for the circuit breaker, which was useful info for the apartment's maintenance team.

Thank you! I thought my Carrier 52SEC514 was falling apart from the noise, but it turns out it's probably just the fan slinger ring. The manual link is super helpful.
