Pairing Instructions
Method 1: Pairing via key combination
Press and hold "ESC" + "+/=" for 1 second. The keyboard enters pairing mode (the
low-battery indicator stays on). Insert the receiver within 20 seconds. If pairing
succeeds, the LED turns off immediately; if pairing fails, the keyboard exits pairing
mode after 20 seconds and the LED turns off.
Method 2: Pairing via the pairing key
Press the pairing key. The keyboard enters pairing mode (the low-battery indicator
stays on). Insert the receiver within 20 seconds. If pairing succeeds, the LED turns
off immediately; if pairing fails, the keyboard exits pairing mode after 20 seconds and
the LED turns off.
Method 3: Pairing via software
Launch the pairing software and insert the receiver into a USB port; pairing mode
is entered automatically. Within 20 seconds, press the keyboard pairing key or press
and hold "ESC" + "+/=" for 1 second to pair. If pairing succeeds, the software
displays <Keyboard pairing successful>; otherwise, it exits pairing mode after 20
seconds.

Function Description
I. Low-Battery LED: Indicates the low-battery and pairing status; it can also
indicate fault points on defective units during repair
1. Pairing status indication — The low-battery LED stays on while the
keyboard is in pairing mode and turns off when pairing succeeds 2. Low-
battery status indication — The low-battery LED blinks when the battery
voltage is low and turns off when the voltage is normal
3. Abnormal function status indication:
1) Normal case-----on power-up, the indicator lights up briefly and then turns
off
2
) Indicator does not light up-----
MCU
not working
3
) Indicator stays on-----
RF
not working
** Numlock + Caps: LED status synchronized with the host
When Numlock/Caps is activated, the LED lights up and stays on for 5 seconds. If
a key is pressed within 5 seconds, the timer resets to 5 seconds (the LED turns off 5
seconds after the key is released). After the LED turns off, pressing a key lights it
up again for 5 seconds
Note: When the low-battery threshold is reached, the low-battery indicator
blinks 5 times. If a key is pressed, the timer resets to 5 seconds, until the battery is
fully drained
