About Connection
①First, try replacing the batteries and confirm whether the keyboard/mouse can be turned on and whether the battery level is sufficient (you can determine this by pressing any key and observing if the indicator light comes on).
②If it can be turned on, insert the USB receiver into a different port, unplug other USB receivers, and then try to re-pair the product. Check whether the light flashes normally during the re-pairing process.
Re-pairing Steps:
- Keyboard:
Remove the receiver and turn on the keyboard switch. Hold down the `ESC` and `Q` keys simultaneously for about 3 - 5 seconds until the power indicator light starts to flash quickly. Release the keys and quickly insert the USB receiver (within 20 seconds). Place the keyboard close to the USB receiver. The indicator light will stop flashing when the connection is successful. - Mouse:
Remove the receiver and turn off the mouse switch. Hold down the mouse wheel and right button simultaneously for about 3 seconds, then turn on the mouse switch. Do not release the buttons immediately. Continue holding them for an additional 3 - 5 seconds after turning on the switch. The indicator light between the left and right buttons will flash quickly, indicating that the mouse has entered pairing mode. Quickly insert the USB receiver (within 20 seconds) and place the mouse close to the receiver. The indicator light will stop flashing when the connection is successful.
About Keys
Replace the batteries and then try to re-pair. If only one or a few specific keys are problematic, press the non-working key firmly for 5 - 7 seconds to see if it starts working normally.
We do not sell individual keycaps. First, check if there is any damage to the key clip. If not, try pressing the key firmly to put it back into place.
About Battery Life
The keyboard and mouse set has an output power of 10 milliamps. The actual battery life depends on the capacity of the batteries used. To calculate the product's sustainable usage time, divide the battery capacity by the output current.
For example, if the battery capacity is 500 mAh (milliamp-hours), the estimated battery life would be 50 hours.
