What do I do if the mouse does not work?

1. Make sure that the mouse is fully charged.
2. Verify that your computer’s power management feature is turned off.
3. Check that the receiver’s USB connector is firmly attached to the USB port on your computer.
4. Make sure you have established a radio link between the mouse and its receiver. See “Establishing a connection between the mouse and the RF receiver” on User Manual.

The RF receiver is recognized by Windows but the mouse pointer does       not move.

1. Repeat the section “Establishing a connection between the mouse and the RF receiver” on page 3 and ensure that the mouse is within range (1.5m) of the RF receiver.
2. If this does not solve the problem, check that the optical sensor on the underside of the mouse lights up. If the sensor does not light up, it is likely that the batteries are flat. Replace the batteries and repeat the above steps again.

When I use the mouse, other wireless devices work more slowly or       fail temporarily – what should I do?

The mouse has 256 identity codes per channel to prevent interference. However, some interference may still occur if there are multiple radio-based devices that operate at 27 MHz, such as a telephone, baby monitor, or toy. To reduce interference, move the mouse’s receiver and the base unit of the affected device as far away from each other as possible.

What do I do if the response time of the mouse is slow or the mouse       intermittently stops working?

1. Increase the distance between the mouse’s receiver and the rest of your computer equipment.
2. Increase the distance between the mouse’s receiver and the base units of other wireless devices.
3. Turn off any wireless devices and their base units that are near the mouse’s receiver.
4. If you are using the mouse on a metal surface, move it and the receiver to a non-metal surface. Metals, such as iron, aluminum or copper, shield the radio frequency transmission and may slow down the mouse’s response time or cause the mouse to fail temporarily.

I can’t use the mouse while another RF mouse is in use – what should I       do?

Reset the identification code. See “Establishing a connection between the mouse and the RF receiver” on User Manual.

Operating Hints For Optimal Performance and RF Reception:

• Turn off your computer’s power management feature before charging the mouse so that your computer doesn’t enter sleep mode, which temporarily halts the charging process.
• Place the receiver at least 8 inches (20 cm) away from all electrical devices, such as your monitor, speakers or external storage devices.
• If necessary, use the three-inch extension cable to keep the receiver away from the computer. Plug the receiver into the extension cable, and the extension cable to the computer.
• Avoid using the mouse on a metal surface. Metals, such as iron, aluminum or copper, shield the radio frequency transmission and may slow down the mouse’s response time or cause the mouse to fail temporarily.
• The mouse will enter a suspend mode at the same time your computer does. To activate the mouse, press any button.
• If your computer has a metal case that contains aluminum or magnesium, use the mouse to the side. The display panel may interfere with the radio frequency signal if you use the mouse directly in front of the computer.
• Never use the mouse on a glass or mirrored surface as these surfaces will cause the mouse to fail temporarily.
• To maximize battery life, use the mouse on a white, or light colored surface. Dark surfaces cause the mouse’s light emitter diode (LED) light to glow brighter, which causes the battery to discharge more rapidly.

Does the keyboard only work with USB2.0 or does it also support USB1.1?

The keyboard works with any USB version from USB 1.1.

I cannot run the BIOS Setup of my computer, as the keyboard starts responding after loading the operating system. How do I do this?

You should re-connect your old PS/2 keyboard and enable the corresponding setting of “USB Legacy Device” (the option can be named differently depending on the BIOS version). This item should be enabled in order for the keyboard to respond immediately after turning the PC on.

Why can’t I input from the keyboard?

The keyboard is not recognized correctly. Please confirm that the keyboard is recognized correctly by the computer.

1. Open [My computer] > [Control panel] >[System] > [Hardware].
2. Click [Device manager].
3. Standard 101/102 key or Microsoft natural keyboard [HID compatible keyboard] are shown in [Keyboard], and [HID compatible consumer control device], [HID compatible system control device], [USB human interface device] are shown in [Human interface device].
4. Similarly, if [USB compatible device] is shown in [Universal serial bus controller], the keyboard is correctly recognized.

   If the display is correct but you cannot input from the keyboard.

   1. Click to select [USB compatible device] in [Universal serial bus controller], and click [Delete] button to delete.
   2. When the confirmation for delete is shown, click [OK].
   3. And then if you click [Update] button, [New hardware] will show, and the computer will setup the keyboard again.

   If the display is incorrect.

   1. [Unknown device] may show in [Universal serial bus controller] or [Other devices]. In this case, you may click to select [Unknown device] and click [Delete] button to delete.
   2. When the confirmation for delete is shown, click [OK].
   3. And then if you click [Update] button, [New hardware] will show, and the computer will setup the keyboard again.
   4. After you setup again, please confirm that you can input from the keyboard.

How can I do if the keyboard is sticky or do not function properly?

If your keyboard develops "sticky" keys, or keys that do not function consistently, most likely a piece of debris is preventing a clean contact with the electronics, and we have developed instructions to assist you in cleaning more thoroughly under the keycaps:

1. Turn off your computer.
2. Gently lift the affected keycap up from the bottom until it clicks open, like it's on a hinge. For the vertically oriented keys, lift from the right side up, hinging on the left hand side.
3. Check under the keycap, using a flashlight if needed, to see if there are crumbs or dust particles collected there that may be interfering with the contact to the keyboard, being careful not to disturb the mechanism, if possible. The best way to clean this area is to use the pressurized air.
4. Check the silicon dome (see image) at the center of the key structure -- is it mushy or off-center?
5. You may want to check another key that is operating correctly in order to compare the structures and operating mechanisms.
6. Once you have examined the key thoroughly, place the keycap back directly over the underlying structure and gently but firmly press down. The keycap should click back into place. Try it now and see if any difference can be noticed.

My computer keeps asking for driver or can not recognize the hardware after connect USB devices.

Windows XP Home Edition and Windows XP Professional are both fully USB 2.0-compliant with the correct drivers. Besides, Windows ME, 2000, and XP get their drivers through Windows Update regularly. Therefore, there’s no need to install any driver to recognize the USB devices.
However, if you still find the message of “USB device not recognized”, “unknown device”, or seeking for driver while connect the USB device to your PC, the possible reasons are:

1. Hardware failure. If you brought 2 USB Hub, please try the other
