5. Setup Guide
5.1. Charging the Device
Before first use, ensure the Rii i25 is fully charged. Connect the provided USB charging cable to the USB charging port on the side of the device and to a standard USB power source (e.g., computer USB port, USB wall adapter).
5.2. Connecting the USB Receiver
- Locate the USB receiver (dongle) in the package.
- Plug the USB receiver into an available USB port on your target device (PC, Smart TV, Android TV Box, etc.).
- The system should automatically detect and install the necessary drivers. This is typically a plug-and-play process.
5.3. Powering On the Device
Slide the power switch, located on the side of the Rii i25, to the 'ON' position. The device's indicator light should illuminate briefly, indicating it is powered on and attempting to connect to the USB receiver.
6. Operating Instructions
6.1. Using the Air Mouse
The Rii i25 features an air mouse function for intuitive cursor control. Hold the remote in your hand and move it in the air to control the on-screen cursor. The air mouse is active by default when the remote control side is facing up.
- Lock/Unlock Air Mouse: Press the dedicated 'Lock/Unlock' button (often depicted as a hand icon or similar, refer to Figure 5) to toggle the air mouse function on or off. This is useful when you need to prevent accidental cursor movements.
- Clicking: Use the 'OK' button in the center of the directional pad for left-click actions.
6.2. Using the Keyboard
Flip the device over to access the mini QWERTY keyboard. When the keyboard side is facing up, the air mouse function will automatically deactivate to prevent unintended cursor movements while typing.
- Typing: Use the keys as you would a standard keyboard.
- Function Keys: Special function keys (e.g., Fn, Shift, Alt, Ctrl) are available for advanced commands.
6.3. IR Remote Control Learning Function
The Rii i25 allows you to program certain keys on its remote side to mimic functions from your existing infrared remote controls (e.g., TV power, volume). The IR learning buttons are typically the red-colored keys at the top of the remote side (refer to Figure 5).
- Enter Learning Mode: Press and hold the 'TV' button (or a similar designated IR learning button) on the Rii i25 until the indicator light starts blinking slowly. This indicates it's in learning mode.
- Position Remotes: Place the Rii i25 and your original IR remote control head-to-head, approximately 2-7 cm apart.
- Learn a Key: Press the button on your original IR remote that you wish to learn (e.g., TV Power). The Rii i25's indicator light should blink rapidly, then stay solid, indicating it has received the signal.
- Assign to Rii i25: While the Rii i25's indicator light is solid, press the corresponding programmable button on the Rii i25 that you want to assign this function to (e.g., the Power button on the Rii i25). The indicator light will blink slowly again, confirming the learning was successful.
- Repeat for Other Keys: Repeat steps 3 and 4 for any other functions you wish to program.
- Exit Learning Mode: Press the 'TV' button again to exit learning mode. The indicator light will turn off.
7. Maintenance
- Charging: Recharge the device when the battery indicator is low or when you notice a decrease in performance. Avoid overcharging for extended periods.
- Cleaning: Use a soft, dry cloth to clean the surface of the device. Do not use liquid cleaners or abrasive materials.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for a long period, ensure it is fully charged and turn off the power switch.
8. Troubleshooting
- Device not responding:
- Ensure the device is powered on (check the side switch).
- Verify the USB receiver is securely plugged into the host device.
- Check if the device battery is charged.
- Try plugging the USB receiver into a different USB port.
- Air mouse erratic or not moving:
- Ensure the air mouse function is not locked (press the Lock/Unlock button).
- Recalibrate the air mouse by placing the device on a flat surface for a few seconds.
- Interference from other wireless devices might affect performance. Try moving closer to the receiver.
- IR learning not working:
- Ensure the Rii i25 is in learning mode (indicator light blinking slowly).
- Make sure the original remote and Rii i25 are 2-7 cm apart and facing each other directly.
- Repeat the learning process carefully, ensuring a firm press on both remotes.
- Note that the IR learning function typically supports the NEC protocol.
- Keyboard input issues:
- Ensure the keyboard side is facing up.
- Check for any physical obstructions or debris under the keys.
9. User Tips
- The air mouse automatically disables when the keyboard side is used, preventing accidental cursor movements.
- While the air mouse sensitivity is generally good, some users may need time to adjust to it.
- For IR learning, if the first attempt fails, repeat the steps until the function is correctly programmed.
- This model does not feature a keyboard backlight.
- Newer versions of the Rii i25 may come with a USB-C charging port, offering improved convenience over older micro USB versions.
- The air mouse function works well with larger interfaces, such as those found on Smart TVs or media centers.
- The device is generally plug-and-play with Linux systems, requiring no additional configuration.
- The IR learning function is primarily designed to learn the NEC protocol.
- The device does not include a built-in microphone for voice search or an earphone jack for audio output.
