Question about Logitech Cordless Desktop Optical 967320-0403 Keyboard

2 Answers

I have a EX 100 wireless keyboard and a wireless mouse. I changes the batteries in the mouse and the next day it said I needed to replace the keyboard batteries as well. I did that on Friday and when I came to work today (Monday) the keyboard doesn't work. The mouse works but I can't type anything. Is it because of changing both sets on batteries? The batteries in the keyboard are new.

    If that didn't work its possible you have the batteries in wrong. Make sure the positive is in the right direction. Bud

Hi,

You just need to reconnect the wireless keyboard, to do this, press on the connect button on the receiver. then on the bottom of the mouse, then press on the receiver again and then on the button in the bottom of the keyboard.


Everything should work normally again, if you just had good batteries in and they are in the right way. If the keyboard still doesn't work check the batteries and try again.

What is logitech 810-000755 used for or what does it do


810-000755 is the part number for the Logitech C-bt44 USB receiver for the Logitech Cordless Desktop EX 100. See http://support.logitech.com/en_us/product/cordless-desktop-ex-100-product/faq#link_19321 . This is the section of the FAQ on using the EX 100 with other USB receivers. The receiver lets select Logitech wireless keyboards and mice communicate with the computer that has this device plugged in. The 810-000755 also works with the Logitech cordless desktop (keyboard/mice) EX 110, and the MK 300. There may be other keyboards and mice that communicate with this receiver. However, newer Logitech keyboards and desktops (keyboard/mice) may not use this receiver.

I hope this helps. Note: the EX 100 uses 2 alkaline AA batteries in the keyboard and 2 alkaline AA batteries in the mouse to communicate with the receiver. I believe the other keyboards and desktops that can communicate with the 810-000755 also use alkaline batteries which last ~6 months before they must be replaced.

Can i connect my wireless logitech keyboard with out the mouse


Yes sir I have had one of those Logitech before and what you have to do it's not magic it's a signal that it gets to let him let him know that it's working properly and you probably need to reboot the signal and then it will probably work properly

Mouse works keyboard does not. changed batteries, reconnected, restarted laptop still the same result


Did you push the connect button on the back of the keyboard? It should be someplace close to where you put the new batteries in.

Hope this helps

Connect an additional wired keyboard to your pc. And when the freeze happens check if the pc responds at all, using the wired keyboard. If its not responding , its an indication of a faulty PSU or motherboard.

Hi there,
Underneath the mouse and the keyboard will be buttons labeled "Connect", you will need to resync with the receiver plugged into your computer. Press the connect button on each device in turn and it will attempt to resync.
If this does not work the next thing is to test with fresh batteries, however it is unlikely that both the keyboard and the mouse would run out at the same time.
Finally try with the receiver right next to the keyboard/mouse, sometimes other devices can interfere with wireless signals (WiFi networks, microwaves, vacuum cleaners etc...).
Good luck!

Hello, try fitting new batteries in the mouse. The top rear half of the mouse slides back and lifts off. You will need 2x AA batteries. Use good quality ones (like Duracell) Regards, nicam49

I have two sets of this product and when they are both being used at the same time one will stop working completely, help.


Hello,

These units work on a radio frequency and if you have two units close together they will interfere with each other. The one that is closer to the receiver or has a stronger battery will usually win the battle. The next problem is they both use the same frequency and it can not be changed. The best option is to get a different brand of wireless keyboard or try a bluetooth keyboard. Bluetooth keyboards operate differently and can be used near each other.

I hope this helps, if so please rate our solution.

Logitech wireless keyboard and mouse (ex 100) won't connect


The mouse and keyborard have to be in direct view of the reciever. Even a small obstruction will effect the operation
