A: If you notice that the cursor speed has suddenly changed (either too slow or too fast), this might be due to accidentally pressing the DPI adjustment button, which is located below the scroll wheel, between the left and right mouse buttons. This button allows you to change the DPI settings, which control the speed of the cursor.

To fix this:

• Simply press the DPI adjustment button again until you reach a comfortable cursor speed.
• There are multiple DPI levels available, so you may need to press it a few times to find the speed that works best for you.

Note:If your cursor is moving very slowly, it is unlikely due to low battery or a dirty trackball. Instead, please try adjusting the DPI setting first.

Tip: Familiarize yourself with the location of the DPI button to avoid pressing it accidentally during use.

A: DPI stands for "Dots Per Inch," which determines how sensitive the mouse is to movement. Essentially, the higher the DPI, the faster the cursor moves across the screen, while a lower DPI means the cursor moves more slowly, providing greater precision.

• Low DPI (e.g., 400): The cursor moves slowly, which is ideal for tasks that require high precision, such as graphic design or photo editing in applications like Photoshop.
• Medium DPI (e.g., 800-1200): This range offers a balanced speed, suitable for general tasks like document editing and productivity work.
• High DPI (e.g., 1600): The cursor moves quickly, which is great for browsing the web or quickly navigating large screens.

Our trackball mouse offers 4 DPI settings: 400, 800, 1200, and 1600. You can easily switch between these settings by pressing the DPI adjustment button. Each level is indicated by a different number of flashes from the LED light:

• 400 DPI: 1 flash
• 800 DPI: 2 flashes
• 1200 DPI: 3 flashes
• 1600 DPI: 4 flashes

If none of these settings meet your requirements, you can further customize the DPI through your computer's settings. This flexibility ensures you can find the perfect sensitivity for your specific needs.

Tip: For precision work like drawing or editing, start with a lower DPI setting. For quick navigation or casual use, a higher DPI setting can save time.

A: This trackball mouse charges using a Type-C cable. For optimal performance and to avoid charging issues, please follow these guidelines:

1. Use the Original Cable: Always use the included Type-C cable for charging. Plug it into a computer USB port or a standard 5V/1A charging adapter. Avoid using high-power chargers or quick chargers, as these may damage the battery.
2. Check for Dust in the Charging Port: Dust or debris in the port can prevent proper charging. Use a small brush or a soft cloth to gently clean the charging port.
3. Try a Different Charging Cable: If the mouse still doesn’t respond (e.g., the indicator light doesn’t turn on), try another Type-C cable to see if that resolves the issue.

When the mouse is low on battery, the indicator light will flash red. Once fully charged, the light will turn green.

Tip: Regularly clean the charging port and avoid using non-standard chargers for reliable performance.

A: If you notice that the cursor is lagging or the scroll wheel is not moving smoothly, it may be time to clean the trackball. Over time, dust and debris can accumulate inside the trackball socket, which can affect performance.

To clean the trackball:

1. Remove the trackball from the mouse. You can usually do this by gently pushing the trackball out from the back.
2. Clean the trackball, the socket, the sensor, and the three white rollers using a soft cloth or a cotton swab. Make sure to remove any dust or debris from all these areas to ensure smooth operation.
3. Reinsert the trackball and check if the performance has improved.

Regular cleaning will help ensure smooth operation of both the cursor and the scroll wheel.

A: If the cursor is not responding, it might be due to the mouse being on the wrong connection channel. This trackball mouse supports three connection channels: Bluetooth 1, Bluetooth 2, and 2.4G wireless. Here's what you can do:

1. Check the connection channel: Make sure you are on the correct channel. You can switch between the channels by pressing the channel switch button. If the mouse is in pairing mode, the corresponding channel light will blink. If it is successfully connected, the light will remain steady.
2. Ensure the 2.4G receiver is connected: If you are using the 2.4G wireless connection, make sure the USB receiver is properly plugged into your computer and that the mouse is set to the 2.4G mode.

Tip: The three connection channels provide flexibility to connect to multiple devices. Make sure you switch to the correct channel for the device you are trying to use.

A: If you are having trouble connecting via Bluetooth, it could be due to the mouse being in sleep mode or a previous connection issue. Here are some steps to troubleshoot:

1. Wake up the mouse: If the mouse has not been used for 30 minutes, it may enter sleep mode to conserve battery. To wake it up, press either the left or right mouse button. Note: Moving the mouse or scrolling the trackball will not wake it up.
2. Reconnection delay: After a Bluetooth connection is interrupted, there may be a few seconds delay when reconnecting. Please be patient and wait for the connection to re-establish.
3. Remove and re-pair the mouse: If the mouse does not reconnect automatically, go to your device's Bluetooth settings, remove the mouse from the list of paired devices, and then reconnect it. Additionally, press and hold the Bluetooth channel button on the mouse until the indicator light starts blinking quickly to enter pairing mode.
