There are two primary issues that have been discussed. One seems to have been resolved - the headphone audio problem. The other is when the scanner is connected to a computer with the USB cable, it wants to jump from Serial Port to Mass Storage Mode.
If you will do things requiring the scanner to be in Serial Port mode, that can be problematic. Whether this is a hardware issue or firmware issue hasn't been said (Uniden hasn't even said they are looking into this matter - there was supposedly a firmware update to deal with that, but I and others still experience the problem).
The Siren App hasn't been finalized. There will be some updates needed to the WIFI dongle whenever that comes out as I understand. And I imagine with the Siren App being something new, there are bound to be bugs. I'm not being negative - such things are facts of life.
However, I believe Uniden is a responsive company and will address issues, they may not do so as quickly as some folks would like, but eventually they do.
These days scanners are like mini-computers. It seems that there are always some patches to operating systems or something "new and exciting" on the horizon. Waiting until the last thing falls into place, might be lengthy.
I purchased mine a few days ago from Gigaparts in Huntsville AL, and would have purchased it sooner if I could have. It's a great scanner, and I'm hearing stuff on it that's not possible on my other digital scanner, a Radio Shack Pro197. Mine has switched from serial to mass storage mode when using the Scanner Screen program, but when using the Butel Arc536 beta in virtual control, it's never had so much as a hiccup.
As the old advertising logo used to say, "Try it, you'll like it!"
So, are the 4700-series mid-digits serial numbers units (that seem to be on the shelves currently) post-issue-factory-fresh-production scanners or reworked-corrected units (despite also having <2600 ending serial numbers)? The 3800-series appeared to be the problem units, no? I just want to finally get my two new units heading my way sans problems and want to ensure production line fresh, un-reopened scanners. Anyone in the know...Paul?? Thanks.
The 535 box does not have the serial number on it! HRO opened the box and the radio had a 3800xxxx serial number. I didn't want to ask them to open all of the boxes, so I'm sticking with my trusty 996T until the dust settles.
