1.Read Card Indicator Light and Buzzer Prompts

  • The LED indicator blinks to indicate the working status and buzzer mode.
  • Read distance: 0 ~ 25000 mm
  • Output power: 0 ~ 33 dBm adjustable
  • Convenient for users to control the working state of the product.

2.LED Indicator Meaning

ColorStatus
Red lightIndicates that the power indicator is on and steady red.
Green lightRF indicator. Blinking green: the reader is receiving or sending data/commands.
Yellow lightRunning indicator. Blinking yellow indicates that the device is running normally.
