Issue: When using a USB 2.0 2.4GHz wireless peripheral device (such as a mouse, keyboard, or headphones) with a PC that also has a USB 3.0 peripheral device plugged in, you may experience erratic operation caused by interference. This is especially likely to happen when using USB 3.0 remote hard drives or flash drives.
This interference may result in:

• • 1- Delayed response to mouse or keyboard inputs
  • 2- Missing keyboard characters or mouse commands
  • 3- Decreased operating distance between the USB 2.0 wireless device and its receiver

There are some techniques that can help early adopters of USB 3.0 to mitigate potential problems with their existing 2.4GHz wireless devices:

• • • 1- If your PC has multiple USB 2.0 connectors available, separate your USB 3.0 and USB 2.0 receivers by as much distance as possible. For example, if your PC has a choice of USB 2.0 connectors, use the one on the opposite side of the PC from the USB 3.0 connector.
    • 2- Position your USB 2.0 receiver as close as possible to your wireless peripheral (mouse, keyboard, headphones, etc.).
    • 3- Use a standard, USB-extender cable to position your USB 2.0 wireless receiver as far away as possible from your USB 3.0 connector.

NOTE: A USB 3.0 connector sometimes referred to as Super Speed USB or SS, normally has a blue plastic insert in the connector. Unlike a USB 2.0 connector which has 4 pins within the connector, a USB 3.0 connector has 9 pins.

• • 1- Move your USB 2.0 wireless receiver to the opposite side of your computer
  • 2- Make sure your USB 2.0 wireless receiver is in the USB 2.0 connector closest to your wireless peripheral
  • 3- Use a USB extended cable to position your wireless receiver as far away from your USB 3.0 peripheral as possible

MOUSE ISN’T WORKING

If your mouse isn’t working, the problem is likely a lost connection. The connection between the mouse and the computer can be lost for several reasons, such as:

• Low battery power
• Using your mouse on metal surfaces
• Radio frequency (RF) interference from other wireless devices, such as:
  1. Wireless speakers
  2. Computer power supplies
  3. Monitors
  4. Cell phones
  5. Garage door openers

Try to rule out these and other possible problem sources that might be affecting your mouse.

MOUSE FREQUENTLY STOPS WORKING

If your mouse frequently stops working and you keep having to reconnect it, try these suggestions:

• Keep other electrical devices at least 8 inches (20 cm) away from the mouse and the host device.
• Move the mouse closer to the computer.

BEFORE RECONNECTING YOUR MOUSE

Before you try to connect your mouse again:

• Replace the batteries.
• Try moving the cursor to verify that it’s working.
• If it’s still not working, follow the appropriate link below to reconnect your mouse.

RECONNECTING YOUR MOUSE

NOTE: Start fresh by removing the existing pairing and then re-pairing.

BATTERY INFORMATION FOR YOUR MOUSE

• Requires 1 AA alkaline battery
• Expected battery life is up to 4 months
• Installing a new battery
  1. When you install a new battery in your mouse, make sure it faces the correct direction

EXTENDING BATTERY LIFE

Your mouse enters standby mode to conserve power when it is not in use. Here are some other ways you can help extend the battery life:

• Use only alkaline batteries. Non-alkaline batteries (such as NiMH,or NiCd) operate at a lower voltage and may affect the battery life.
• Avoid using your mouse on dark or transparent surfaces, such as glass. These surfaces cause the optical sensor to use more power.
• Make sure replacement batteries are new and within the manufacturer’s expiration date.
• To Power up the mouse battery, Use the On/Off switch help to conserve power.
• Your Mouse MX31 Have Smart sleep mode, so if you sleep your mouse will sleep too.

If the cursor isn’t following the movements of your mouse, we suggest you:

• 1- Use a mouse pad.
• 2- Avoid using your mouse on:
  1. Glass and other see-through surfaces
  2. Reflective surfaces, such as mirrors and metal desks
  3. Wood grains and grooved surfaces
• 3-Try the mouse on a piece of white paper to make sure it isn’t a tracking issue on the particular surface you’re using.

If this solution doesn’t work, restart your computer and try again.

if your mouse double-clicked from the first day of usage, check the Windows setting called Single-click to open an item. This option makes a single mouse click act as a double click. Disable this setting to return the mouse to the standard one click option.

In an ideal environment, your mouse or keyboard can operate up to 30 feet (10 meters) away from the Computer.

If you’re not getting this distance, try these suggestions:

• 1- Replace the batteries or make sure your mouse or keyboard is fully Power.
• 2- Move devices that emit radio waves or could cause radio interference away from your work area.
• (Examples: cell phones, radios, wireless routers, microwaves).

To determine if your environment is shortening your operating range, try using your device in a different environment to see if the distance improves. If it does, look for other possible sources of interference you can remove from your work area.

If this solution doesn’t work, restart your computer and try again.

The MX31 mouse is supported by these operating systems:

Before you try to connect your mouse again:

• Windows 7.
• Windows XP.
• Windows Vista.
• Macintosh OS X 10.5 or above.
• Linux kernel 2.6 or above.
• Windows Vista.
