Can't say for sure if you don't provide the product link. The 536HP requires a microSD card, can support up to 32GB. Standard SDHC is too big & won't fit in the slot
They say you get a little more life out of the high endurance cards. I think I remember seeing an Upman post years ago that Uniden was starting to use those kind for that reason.
They have gone way down in price and it seems the 32 GB cards are getting more "extinct".
