Hello, does anyone have a manual for this beauty?
(Logitech "MouseMan (TM), Cordless", modelnumber "M-RA12")
A link or a scan would be appreciated 😉

The attachment IMG_20230112_161034_small.jpg is no longer available

Building my own PCs since 1991 - for my retro builds it's "no CF-disks, no Floppy emulators, no modern cases etc.", only the real and authentic stuff whenever possible.

No response? ... does anyone at all have this cordless mouse?
It would be great if you could help me and describe the procedure to set the channels correctly.

The only thing I found is this MS docu: https://ftp.zx.net.nz/pub/archive/ftp.microso … n-us/73/344.HTM
That exact mouse is not not listed on the 1997+ Logitech archive or wikipedia....

added: did find this about the frequencies used: https://docs.rs-online.com/bf54/0900766b8015eda4.pdf which mentions the M-RA12 but no real manuals yet....

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

Thank you, but nope, the first one is of no help to my problem (BTW this mouse has a red LED at the bottom) and the latter I already knew (which is no help either) 🙁
It seems that this bit of HW is another one from the void of computer history ...

Did you check this further support page from @Horun's 2nd link? - https://web.archive.org/web/20020823224506/ht … tentid=4549#one

Cordless One Technology

Verify the receiver is properly connected and that the battery is installed. Also, make sure that the mouse and the receiver are on the same channel so they can operate together. The receiver must lie horizontally, with the light on top, to work properly. There are 8 channels to choose from, although channel 4 is recommended. Check your receiver to make certain the channel switch hasn't been moved from channel 4, and the mouse and receiver are ready to go on channel 4. You should only change the channel from this default setting if another Cordless MouseMan is operating within one meter (39 inches) of your MouseMan receiver. Each channel setting has two positions, a short distance apart. Try both positions. One may work better than the other.

1. Choose the channel on the receiver. Turn the channel selector on the receiver to channel 4. This switch is on the right side of the receiver when the cord points away from you.

2.To put the mouse in Programming Mode, pick up the mouse and turn it over with the battery installed and belly door on. Slide the belly door part way open. Stop when the line on the belly door is at the 'P' (for "Programming Mode") on the bottom of the mouse. With the belly door in this position, the rectangular hole is just over the mouse light inside the mouse. When the light flashes, the mouse is operating and ready for the channel to be set.

3. Set the channel of your mouse. Click any mouse button while you watch the receiver light, pausing after each click. When the receiver light starts flashing, the mouse and receiver are working on the same channel. Each time you click a mouse button in Programming Mode, the mouse light flashes the same number of times as the number or the new channel it is on. It then pauses briefly, then repeats the channel number over and over. When the receiver light flashes, it is an indication that the mouse and receiver are communicating on the same channel.

4. Close the belly door. When the Cordless MouseMan is operating normally, the receiver light flashes every time the mouse sends a message to the computer. As long as the mouse and receiver are on the same channel and you move the mouse and click the buttons, the receiver light flashes continuously.

Many thanks for this very helpful information - really sorry, I think I've looked for something more manual-like first.
Unfortunately the (quite expesive) CR17335SE lithium battery went dead, so I have to buy a new one first before testing 🙁
