Logitech has released an RF- (radio frequency) based serial, cordlessmouse called the Cordless Mouseman. Standard mouse troubleshootingtechniques generally apply with this mouse; however, some additionalconsiderations should be taken into account when troubleshooting thismouse.
In addition to standard troubleshooting techniques, follow these stepswhen troubleshooting the Logitech Cordless Mouseman:

  1. Verify that the mouse and the receiver are on the same horizontal plane (that is, both are on the desktop). It is acceptable for the receiver to be out of the line-of-sight of the mouse (that is behind the CPU); however, both should be on the same horizontal plane for proper operation.
  2. Verify that the mouse is no greater than 2 meters (about 5 feet) from the receiver because this is the maximum reception distance for the Cordless Mouseman.
  3. Temporarily remove any possible source of RF interference, such as a cordless phone or other transmitting device, from the general area.
  4. Check for the correct mouse driver. The latest version of the Cordless Mouseman is version 5.01, which is dated 3/19/91 and has a file size of 33,977 bytes.
  5. Verify that the mouse (transmitter) and the receiver are operating at the same frequency by removing the battery from the mouse for a few seconds and then placing it back into the mouse. This will reset both the mouse and the receiver to frequency 4. Frequencies 1-7 are available and can be selected manually so that the receiver and mouse match each other at another frequency if desired. To set the frequency manually, you must be at the MS-DOS command prompt.

    Do the following:

    1. Take the cover off of the mouse and note the number of flashes per second that the green light indicates--this number is the current frequency.
    2. Use the left mouse button to set the frequency lower and use the right mouse button to set the frequency higher.
    3. Turn the dial on the receiver to the same frequency number that you set the mouse to.
  6. Review the AUTOEXEC.BAT file to ensure that there is a MODE command to initialize the applicable COM port for 9600 bits per second (BPS) (that is, mode com1:96,n,8,1,p).

    Also, from Windows, review the Settings option (accessed by choosing the Ports icon in Control Panel) to ensure that the port being used is set at 9600 BPS. This setting is required for the Cordless Mouseman to operate correctly.
  7. Make sure the COM ports are correctly configured. The Logitech virtual mouse driver (LVMD.386) is hard coded for the standard base port addresses and interrupt requests (IRQs). The base addresses for COM1 and COM2 should be 3F8h and 2F8h, respectively. If the COM addresses are not configured correctly, or the IRQs are not standard, the Logitech series mouse fails to work in 386 enhanced mode.
  8. If you are running Windows 3.1 in 386 enhanced mode, you may encounter problems, such as an unresponsive pointer, when the MS-DOS Prompt or any MS-DOS-based application is run in a window. To correct this problem, do the following:

    1. Change the baud-rate setting for the mouse driver. To do this, add the following line to the [LogiMouse] section of the SYSTEM.INI file:
    2. Include the 1200 option on the command line that loads the MS-DOS Logitech mouse driver (which is provided with Windows 3.1) as follows:
      LMOUSE 1200
      Add the above line to your AUTOEXEC.BAT file to load the mouse driver each time you start your system. The next time you start Windows, your mouse should work correctly.
NOTE: The command lines logimenu and click, which are usually loaded from the AUTOEXEC.BAT file, areincluded with this mouse as well as other Logitech mice. They areterminate-and-stay-resident programs (TSRs), and as such, may causeproblems with Windows installation and/or operation.
