Cannot make USB connections correctly
Was the MMP-2 recognized?
Disconnect the USB cable, and then re-connect it.
If another USB device is connected, try connecting only the MMP-2.
It is possible that the computer did not correctly recognize or initialize the MMP-2. Leave the USB cable
connected to the MMP-2, and restart your Macintosh. If the connection is still not achieved, exit your
Macintosh and turn off the power of the computer. Then turn on the power of the computer once again,
and start up your Macintosh.
The computer cannot recognize the MMP-2 when the USB connector of Macintoshs keyboard is used. Re-
connect the USB cable to the USB connector of the main body.
The MMP-2 does not recover correctly from sleep mode
After your Macintosh has been in sleep mode, exit the software and re-start it.
* We recommend that you make Energy saving settings in the Control panel so that your computer does not enter sleep mode.
Macintosh hangs up
Did you try to plug and unplug USB cable during the booting of MMP-2 editor?
It is possible for your Macintosh to hang in case plugging and unplugging of USB cable is done during the
MMP-2 editor is booting. Please do plugging and unplugging with confirmation that MMP-2 editor is not
booted.
Did you try to communicate with MMP-2 without establishing connection via USB?
It is possible to hang or freeze if you try to send data from the MMP-2 Editor to MMP-2 unit without
turning the power of MMP-2 unit on or connecting your Macintosh with MMP-2 unit using USB cable.
Please confirm MMP-2 unit and your Macintosh is correctly connected via USB and the power of MMP-2
unit is turned on before the communication of MMP-2 Editor and MMP-2 unit.
Did you booted MMP-2 editor before turning the power of MMP-2 unit on?
MMP-2 editor is set to obtain setup status of MMP-2 unit immediately after booting. In order to avoid
hanging or freezing, please boot up MMP-2 editor after connection of MMP-2 unit with your Macintosh
and turning the power on.
