C1: Bluetooth Pairing Indicator
The blue light flashes when the keyboard is pairing with Bluetooth. It turns off once the Bluetooth connection is established.
C2: Power Indicator
When the battery is correctly installed and the keyboard is powered on, this indicator shows green for 3 seconds before turning off.
C3: Low Voltage Indicator
When the keyboard's voltage is low, this red LED flashes.
Sleep Mode
After 20 minutes of inactivity (no keys pressed), the keyboard will enter a sleep state to conserve power. Pressing any key will wake it up and automatically reconnect to the last connected device.
Low Voltage Alarm
A low voltage alarm is triggered when the battery level drops. The green light will flash if the voltage is lower than 2.3V. If the voltage falls below 2.1V, the keyboard will shut down.
Wireless Performance
According to CLASS2 requirements, the effective wireless working distance, with no obstacles, is greater than 10 meters.
Current Specifications
Key press current (when LEDs are off): 0.8mA - 1.2mA.
No-key standby current: 0.5mA - 1.0mA (optimized to be as low as possible while maintaining connection).
Sleep current (after 20 minutes of inactivity): 0.01mA - 0.04mA.
