Question about Logitech Cordless MX Duo 967300-0403 Keyboard

Random Eradic Behavior

Frequently I experience connection issues with my cordless keyboard. It will all of a sudden not work. Then it will work. I have followed the reconnect instructions, made sure my batteries were fresh & even reset my keyboard (following Logitech's instructions)--all to no avail. Once it finally does connect, and I'm doing my work, all of a sudden (at random) web addresses stored in the 'Hot keys' began to open at will(as in uncontrolable--30-40 or more), Logitech's "main menu" & it's link to proprietary services "take off" and characters will "run away" in whatever field I am trying to type in, e.g., on a document, in the save box, in the web browser line. The only way to stop the characters is to press delete & escape simultaneously. Not doing this will result in the keyboard typing "thousands" of characters wherever it will. I enjoy the features of this keyboard, but after about a year of this nonsense, including no response from Logitech Tech. Support & no listing on their site, I'm ready to throw it away & buy another brand. My disappointment with the quality of this product is immense. Any suggestions or comments would be much appreciated. Thanks!

Re: Random Eradic Behavior

After having similiar problems with two wireless keyboards & mice from Logitech, I cured the problem by buying a Microsoft product. So far so good.

My GE wireless mouse 20331 is acting erratic and moving all by itself. I've changed options in control panel and it still is doing this. sometimes when I point and click it jumps to something else not...

the first thing that I would recommend is making sure that it is clean underneath since it is optical debri on the laser area can cause eradic behavior. My second suggestion would be to uninstall the software that came with it and just use the standard controller. I had to do that with a trackball that I was using because the software that came with the trackball wasnt playing nice with the operating system but once I removed that software the unit worked fine.

I have the keyboard but that's all....I need help

Hello Glennfulcher,
The Adesso WKB-4000US wireless keyboard is a great one! I use to have one. What problems are you having with the keyboard? If you are having issues connecting it to the transmitter I would first suggest you check any cordless phones you have around the house. As the WKB series operates at 2.4GHZ so do most cordless phones. This can cause a transmission error with your keyboard. Try these steps if you are having connectivity problems. Because this is the most common connection problem with wireless keyboards and mice.
1. Check all cordless phones for frequency range. 2. If you find a close 2.4 GHZ cordless phone unplug it. 3. Attempt to reconnect the keyboard to the transmitter.
As I am not 100% sure what your question is I'll just give a quick summary of links that may help you get started.

If this answer was helpfull to you please write a quick review of my service I'm trying to work my way to expert help :)
Thanks always, Vex

Suddenly not responding. have replaced batteries and pressed connect button underneath. stopped working while i was working it. maybe ive pressed a button somewhere

You have to download the software from and install it. The software will help you encrypt a connection and make it start working again. The software will prompt you to type in a set of numbers and the connection will be there again. Don't worry... your mouse and keyboard are not broken. This happens quite frequently.

I Belive this is the link you need.... according to the picture...,en

if not then just goto and click on support.

Cordless Destop EX110 Keyboard is inoperable. Batteries have been replaced and connect button pressed. HELP!

Sounds like your keyboard has died...Try to perform a reboot, and make sure the battery is seated correctly. You will most likely have to get it replaced. I recommend going with a Microsoft wireless keyboard and mouse. Its a lot better than Logitech!!

if you're having issues with a "mighty mouse" let me tell you that no matter how well you clean it, the problem will continue. If you can't get a free replacement from Apple, the best experience for us at my office has been to move to Logitech bluetooth mice. Logitech V270 Cordless Optical Bluetooth Mouse works great and you have all the functions you need like scrolling, right and left click, etc.

If you know the batteries are good, then turn the keyboard over and find the small reset/connect button and press it. This resets /connects the board to the receiver. If it still doesn work, press the button on the receiver and then the mouse. Hope this is of help to you. Bud

Does this happen always or only in this game? If it is only in this game, then you may want to consult the game manual. If not, then it could be interference that may be causing the problem.

Any electrical device, such as the computer monitor, Zip drives, speakers, etc., can cause interference with cordless products. Most likely, this will effect tracking of pointing devices or the range of the device. Also, using cordless devices on a metal desk or a desk with a metal frame can cause problems with pointing device behavior and range. To resolve these types of issues, try moving the receiver at least 8 inches away from other electrical devices. Interference issues can also be resolved by moving the mouse closer to the receiver. You may also want to experiment with different locations and positions for the receiver, including moving the receiver to an upright/vertical position or rotated to a different angle. Another alternate solution is to elevate the receiver by placing it on a CD ROM case or other item.

Please let me know if this helped..
