Don't you mean 457 kHz or is it really 475 kHz?
It is almost certainly 457 kHz, I have been on trips with people who use the Tracker DTS and it always picks up on my Pieps which is the standard 457. It would be the most useless thing ever to sell a 475 kHz beacon so I am almost certain that its just a typo.
Hopefully this helps.
