3. Setup Guide
3.1 Charging the Mouse
Before first use, it is recommended to fully charge the mouse. Connect the supplied USB-C charging cable to the mouse's charging port and to a USB power source (e.g., computer USB port, USB wall adapter). The mouse features a 500mAh lithium battery, providing over 130 hours of continuous operation on a full charge.
3.2 Connecting the Mouse
The MCHOSE A5 series offers versatile tri-mode connectivity: 2.4GHz wireless, Bluetooth, and wired (USB-C).

3.2.1 2.4GHz Wireless Connection
- Locate the 2.4GHz wireless receiver (USB dongle). For A5 Pro and A5 Pro Max models, a Receiver Extension Adapter is included.
- Plug the wireless receiver into an available USB port on your computer.
- Turn on the mouse using the switch on its underside and select 2.4GHz mode.
- The mouse should automatically connect. If not, press the pairing button (if available, refer to specific model instructions) or cycle the power switch.

3.2.2 Bluetooth Connection
- Turn on the mouse and switch it to Bluetooth mode (refer to the switch on the mouse's underside).
- On your computer or device, go to Bluetooth settings and search for new devices.
- Select "MCHOSE A5" (or similar name) from the list of available devices to pair.
3.2.3 Wired Connection
Connect the supplied USB-C cable directly from the mouse to a USB port on your computer. The mouse will function as a wired mouse and charge simultaneously.
3.3 Software Installation (Optional)
For advanced customization, including DPI settings, button remapping, and macro creation, download and install the official MCHOSE software from the manufacturer's website. This software allows you to unlock the full potential of your gaming mouse.
4. Operating Instructions
4.1 Basic Functions
- Left Click: Primary action.
- Right Click: Secondary action/context menu.
- Scroll Wheel: Scroll up/down, middle click.
- Side Buttons: Typically for forward/backward navigation in browsers or customizable in software.
4.2 DPI Adjustment
The MCHOSE A5 series features a PAW3395 optical sensor with up to 26,000 DPI. The mouse typically has a dedicated button (often on the top or bottom) to cycle through preset DPI levels. You can customize these levels (400/800/1600/3200/6400/26000) using the MCHOSE software.
4.3 Polling Rate
The A5 Pro and A5 Pro Max models support up to a 4K Hz polling rate, while the A5 Ultra supports an 8K Hz wired and 4K Hz wireless rate. Higher polling rates reduce latency, providing a smoother and more responsive cursor movement. This setting can usually be adjusted via the MCHOSE software.

5. Maintenance
5.1 Cleaning
To maintain optimal performance, regularly clean your mouse. Use a soft, dry cloth to wipe the surface. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the mouse. Avoid harsh chemicals or abrasive materials.
5.2 Battery Care
To prolong battery life:
- Avoid fully discharging the battery frequently.
- Store the mouse in a cool, dry place when not in use for extended periods.
- Use the provided USB-C cable for charging.
6. Troubleshooting
6.1 Mouse Not Responding
- Ensure the mouse is charged.
- Check the power switch on the underside of the mouse and ensure it's in the correct mode (2.4GHz, BT, or Wired).
- For 2.4GHz wireless, ensure the USB receiver is securely plugged in and the mouse is in 2.4GHz mode. Try a different USB port.
- For Bluetooth, ensure Bluetooth is enabled on your device and the mouse is in pairing mode. Re-pair if necessary.
- For wired connection, ensure the USB-C cable is securely connected to both the mouse and the computer.
- Try restarting your computer.
6.2 Erratic Cursor Movement
- Clean the optical sensor on the underside of the mouse.
- Ensure you are using the mouse on a suitable surface (e.g., a mouse pad).
- Check for interference from other wireless devices.
- Adjust DPI settings if the cursor is too sensitive or not sensitive enough.
6.3 Connectivity Issues
- If experiencing lag or disconnections in wireless mode, ensure the receiver is close to the mouse. Using the receiver extension adapter can help.
- Update mouse drivers or software if available.
