• When the USB cable is connected, approximately 15 seconds (or more) may be required for the

MA-1EX to be recognized.

• Is the USB cable connected correctly?

Make sure that the MA-1EX and computer are connected correctly by the USB cable.

• Can USB be used on your computer?

Refer to the owner’s manual for your computer, and make sure that it is able to use USB.

• Does your computer or USB hub have sufficient power supply capacity?

The MA-1EX cannot be connected if insufficient power is supplied to it. Check whether one of the

following cases apply.

If you are using the MA-1EX with a notebook computer that is running on its battery, operation may be

unreliable with some models of computer. If this is the case, connect the AC adaptor to your notebook

computer.

The power conservation mode of your computer may limit the power that is supplied to USB. Check the

settings of your computer.

In some cases, the MA-1EX cannot be used with a bus-powered hub (a hub that does not contain a power

supply). Please use a self-powered hub (a hub that contains a power supply).

• Does your computer meet the USB specifications?

If you are using a computer that does not meet the USB specifications (such as a homemade computer),

operation may be unstable. In such cases, you may be able to solve the problem by connecting a USB hub

that contains a power supply.

• Could other USB devices be connected?

When installing, all USB devices other than the MA-1EX should be disconnected from your computer.

If you have connected the MA-1EX to an external USB hard disk, please connect the MA-1EX directly to a

USB connector on the computer itself.

• Could other applications or resident software (such as a virus checking program) be running?

Installation may not occur correctly if other programs are running. Be sure to close all other programs

before installing.

• Are the power conservation settings of your computer turned off?

If power conservation settings are turned on for your computer, disable these settings. (For details on how

to disable them, refer to the owner’s manual of your computer.)

• Is there enough free space on your hard disk?

Delete unneeded files to increase the amount of free space.

After deleting the file(s), empty the recycling bin.
