3.2 Moddau Cysylltedd
The ML903 supports three connectivity modes:
- Modd Gwifredig (USB-C):
Connect the USB-C cable directly from the mouse to your computer. The mouse will function immediately, and it will charge simultaneously. This mode is plug-and-play. - Modd Diwifr 2.4GHz:
For optimal performance, use the magnetic charging dock which acts as a 4K Hz transceiver. Connect the dock to your computer via USB. The mouse will automatically connect to the dock. Alternatively, you can use the smaller 2.4GHz USB dongle directly plugged into your computer for standard 1K Hz polling rate. Ensure the mouse's mode switch (located on the underside) is set to 2.4G. - Modd Bluetooth:
Turn the three-position switch on the underside of the mouse to the right (Bluetooth mode). Long press the Bluetooth coding key (usually a small button near the switch or on the underside) to enter pairing mode. The mouse's indicator light will flash. On your computer or device, search for Bluetooth devices and select "Thunderobot ML903" to pair.

4. Gweithrediad
4.1 Addasiad DPI
The ML903 mouse features a dedicated DPI button, typically located behind the scroll wheel. Press this button to cycle through different DPI sensitivity levels. Each DPI level is often indicated by a distinct RGB color on the mouse or charging dock, providing quick visual confirmation of your current precision setting.
4.2 Cyfradd Pleidleisio
The ML903 supports up to a 4000Hz polling rate when used with its magnetic charging dock/transceiver. This high polling rate minimizes input lag, providing extremely smooth and responsive tracking, crucial for competitive gaming. When using the standard 2.4GHz dongle or Bluetooth, the polling rate will be lower (typically 1000Hz or less).
