The code that

Mode one: key combination code
At the same time, short press the “ESC” + “+/=” key for 1 second, the keyboard into the coding mode (low voltage indicator light is long on), the 20S insert receiver code successfully, LED immediately extinguished; Code failure, the 20S after the keyboard exit code mode, LED out;
Method two: on the code key code
Press the key to code, the keyboard into code mode (low voltage indicator light is long), insert the receiver in the 20S. Code success, LED immediately extinguished; Code failure, the 20S after the keyboard exit code mode, LED out;
Method three: software code
Open the code matching software, insert the receiver into the USB interface, and automatically enter the code matching mode. Press the keyboard code matching key or “ESC” + “+/=” key for 1 second for code matching within 20 seconds. If the code matching is successful, the software will display < keyboard code matching is successful >; Otherwise, the 20S after the launch of the coding mode.

Functional description

one Low voltage LED lamp: used to indicate low voltage and code status; At the same time in the maintenance can be used to prompt the problem points of defective products

1.  Code status indication — the keyboard enters the coding mode, the low voltage LED is always on, the code is successful, the low voltage LED is extinguished
2.  Low voltage status indicator — when the battery is at low voltage, the low voltage LED flashes, the voltage is normal, the low voltage LED goes out
3. Abnormal function state indication:

1. Under normal circumstances — power on, the indicator lights up and then goes off
2. Indicator light is not on — the MCU is not working
3. Indicator light is always on — RF is not working or EEPROM is not working

II. Backlight function

1. The keyboard is powered on and the backlight panel is turned on by default.
   Press FN+ Scrlk to turn on/off the keyboard backlight

2. The brightness of the backlight is divided into three sections. The default is the second section. Press FN+Page Up to increase the backlight brightness and FN+Page
   Down to reduce the backlight brightness.

3. The backlight will automatically turn off when the keyboard and receiver are disconnected.

4. When the keyboard keys do not move, the backlight will be turned off after 2MIN.

** NUMLOCK + CAPS 2 LED states can be synchronized with the host
When the NUMLOCK/CAPS function is turned on, the LED will be on and indicate for 2MIN. If there are keys in 2MIN, the LED will be on for 2MIN again (the keys will be off after the 2MIN release). If there are keys, the LED will continue to be on for 2MIN after the light is off
Note: The low voltage indicator will flash 5 times after reaching the set value. When the key is pressed, the time will be reset for 2MIN until the power is exhausted
