4.1 MCU LED INDICATORS
On the front panel, locate beneath the removable LEDs cover are five diagnostic LEDs. There
indications are described in the following table separately:
Identifier Color Indication
HIGH Green RSSI indicator which indicates the input field strength.
ON= the DL input field strength is more than -40dBm.
OFF= the DL input field strength is less than -40dBm
MID Green RSSI indicator which indicates the input field strength.
ON= the DL input field strength is more than -50dBm.
OFF= the DL input field strength is less than -50dBm
LOW Green RSSI indicator which indicates the input field strength.
ON= the DL input field strength is more than -60dBm.
OFF= the DL input field strength is less than -60dBm
RUN Green Operation. ON= normal operation, flash= during initialization
OFF = no power supply / MCU operating problem
ALARM Red System Alarm, ON = Failure Alarm, OFF= operating normally
