I know nothing about this equipment so please don't ask!
Manufacturer's Contact Information:
Uniden America Corporation
6225 N. State Highway 161, Suite 300
Irving, TX. 75038, USA
Web Site: http://www.uniden.com
In March 2000 RELM Corp. purchased the entire private radio product line.
Bear in mind that Uniden of Japan is both a manufacturer of Uniden products and a contract manufacturer. Uniden private labels / labeled for Bearcat, Radio Shack / Realistic, Panasonic, Sony, and several other well known brands. Uniden (under its own name) dipped its toe into the USA land mobile pool, and decided to not go swimming.
You should read this page before any of the other articles
here in the Uniden section.
Uniden Introductory Information An introduction to the Uniden equipment, with background, history, some model-specific information,photos, and other miscellaneous items.
Most of the info below is here because at some time or another either the author of this page or a friend needed to locate this information, and we decied to post it here in case somone else needed it as well.
Consumer Electronics Equipment:
|While looking for Land Mobile equipment manuals I stumbled across a consumer elctronics equipment owner's manuals download web page. If you are looking for an owner's manual on almost any current Uniden consumer product i.e. Cordless Phones, VoIP Phones, Business Phones, Marine Electronics, CB Radios, Scanners, Digital Cameras, GPS Navigation, Cellular Phones, Pagers, Radar Detectors, Satellite Receivers, Laptop and Palm-sized Computers, Modems, etc. go to this Uniden page and select what you are looking for. Note that the "Two Way Radios" option is only bubble-packed consumer FRS radios, i.e. nothing in Land Mobile. And there is no older equipment listed.|

A note on the Uniden MR8100 Scanner: Introduced in 1989, this was one of
the first scanners that had a serial port and matching computer software that
could load the preprogrammed channels, in this case 10 banks of 10 channels.
The advertised frequency range was 29-54, 118-174, 406-512, 806-956 MHz in AM
and FM. This was not the "full" range, and the full range could be unlocked if
you knew the secret key... In the Uniden software, make sure "Shift Lock" and
"Num Lock" are off, then Press (ctrl-alt-p). You will see "ENTER CODE:". Turn
"Shift Lock" on. Enter ECPA1986

|I found this ZIP file on another web site... I do not have an MR8100 to test it with, and I have no idea how complete it is: Uniden MR8100 Service Procedures and Specs about 1 MB ZIP file.|
|Anyone have any other documentation for the Uniden MR8100 scanner?|
Land Mobile Equipment:
|The "Commercial Communications Division" of Uniden America was in Fort Worth, Texas. Repeater-Builder is looking for articles on the Uniden desktop repeaters (especially the ARH-351, ARU-251 and ARU-351), and other land mobile equipment such as the AMX-501, SMH-400G, SPU-416K, etc. Also any programming software. Uniden Land Mobile Radio is pretty much long gone (the company focus is in other markets) so there's not much available to support any use of their equipment. The equipment is pretty much useless unless you have everything to place it in service... and I mean everything. So anything that is made available here will help the rest of us continue to use the Uniden equipment that is out there. And donations can be made anonymously.|
