Attention
When the keyboard switches to BT mode for the first time, it directly enters pairing mode,
and the corresponding LED indicator light is in a flashing state. When the device searches for the
BT name, click "pairing" to connect and use it.
If the keyboard is already connected to a device in BT mode and the device has not been
deleted or unpaired, when switching to BT mode, the device will automatically reconnect and can
be used immediately.
Priority should be given to connecting to BT5.0 on WIN10/11. Some old computers may not
be able to find BT5.0, so simply connect to BT3.0.
Sleep mode
•If there is no key operation on the keyboard for 5 seconds, it enters sleep mode and all indicator
lights are off;
Pressing any button again will automatically restore it to its original state.
Low voltage indication
•When the voltage of the keyboard drops below to 3.2V, the red LED flashes.
