Portronics Bubble 3.0 keyboard
for Laptop, PC, Smartphone, Tablet
Connecting via Bluetooth (for up to 3 devices)
The Bubble 3.0 typically allows pairing with up to three devices via Bluetooth.
Switch to Bluetooth Mode: Locate the power/mode switch on the keyboard (often on the side or back) and slide it to the BT (Bluetooth) position.
Select a Pairing Channel: The keyboard usually has dedicated keys (often \text{Fn} + \text{Q}, \text{Fn} + \text{W}, and \text{Fn} + \text{E}) to switch between the three Bluetooth connections.
Press and hold the desired pairing key (e.g., \text{Fn} + \text{Q}) for a few seconds until the corresponding LED indicator light starts blinking (fast or slowly), indicating it's in pairing mode.
Enable Bluetooth on your device: Go to the Bluetooth settings on your laptop, tablet, or smartphone.
Pair the Keyboard: Look for the keyboard in the list of available devices (it may be named something like "Portronics Bubble 3.0" or similar). Select it to complete the pairing. The LED on the keyboard should stop blinking and remain steady when successfully connected.
Switch between devices: Once paired, you can switch between your connected devices quickly by pressing the \text{Fn} key plus the corresponding channel key (\text{Q}, \text{W}, or \text{E}).
Connecting via 2.4 GHz USB Receiver
This method uses the small USB dongle that comes with the keyboard.
Switch to 2.4 GHz Mode: Locate the power/mode switch and slide it to the 2.4 GHz or Wireless position.
Insert the Receiver: Plug the USB receiver (dongle) into an available USB port on your computer or laptop.
Automatic Connection: The keyboard and receiver should automatically connect within a few moments. A single LED indicator on the keyboard should become stable when the connection is successful.
Note on Re-pairing the 2.4 GHz Dongle:
If the 2.4 GHz connection is not working, you may need to manually pair the dongle with the keyboard. A common method is:
Slide the switch to the \text{2.4 GHz} mode (all three LEDs may blink).
Press and hold \text{Esc} and \text{Q} keys together on the keyboard for about 3 seconds.
While still holding these keys, insert the USB dongle into your device's USB port.
Once paired, the lights should stop blinking, and only one LED will remain stable.
