If the match is successful, the software will display<Keyboard match successful>; Otherwise, the code matching mode will be launched after 20s. 2.4G wireless keyboard Ver7.0
Functional description
Low voltage LED light: used to indicate low voltage and code checking status; At the same time, it can be used to indicate the problem points of defective products during maintenance
- Code matching status indicator – When the keyboard enters code matching mode, the low voltage LED remains on. If the code matching is successful, the low voltage LED goes out
- Low voltage status indication – When the battery is at low voltage, the low voltage LED flashes, the voltage is normal, and the low voltage LED goes out
- Indication of abnormal functional status:
- Under normal circumstances – when powered on, the indicator light turns on once and then goes off
- Indicator light not on – MCU not working
- Indicator light constantly on – RF not working or eeprom not working Numlock+Caps 2 LED statuses can be synchronized with the host When the Numlock/Caps function is turned on, the LED lights up and indicates 5 seconds. If a button is pressed within 5 seconds, the timer will be reset for 5 seconds Seconds (the button will turn off 5 seconds after being released), and if any button remains on for 5 seconds after the light goes out
Note:** After the low voltage indicator reaches the set value, it starts flashing 5 times. When a button is pressed, the timer will be reset for 5 seconds until the battery is depleted
