The TU has two LED indicators: 
 

•  Power LED (Green) – This indicator shows that the TU is operating, and has battery power. 
•  Detect LED (Amber) – This indicator shows that the TU has detected voltage (when in NCV or External 

Mode) or a light level change (when in Light Mode). 

 
 

•  Startup – During initial power-up, the TU shall test the communications between the MCU and the RF 

System.  If successful, the Detect LED shall briefly light and then go out. 

•  EEPROM Init – If the EEPROM memory is corrupt or not yet programmed, the MCU shall re-program 

the data and clear all unused locations.  During this process, the Detect LED shall briefly flicker at a > 
5Hz rate.  Under normal circumstances, this indication shall only occur after the MCU is programmed. 

•  Channel Select – The Detect LED shall flash at a 2Hz rate. 

 
 

The RU has three LED indicators: 
 

•  Power LED (Green) – This indicator shows that the RU is operating, and has battery power. 
•  Detect LED (Amber) – When a wireless connection is present, this indicator is a mirror image of the 

TU’s Detect LED.  It shows that the TU has detected voltage (when in NCV or External Mode) or a light 
level change (when in Light Mode). 

•  Communication LED (Yellow) – This indicator shows that the TU and RU are in communication. 

 
 

•  Startup – During initial power-up, the RU shall test the communications between the MCU and the RF 

System.  If successful, the Detect and Communication LEDs shall briefly light and then go out. 

•  EEPROM Init – If the EEPROM memory is corrupt or not yet programmed, the MCU shall re-program 

the data and clear all unused locations.  During this process, the Detect and Communication LEDs shall 
briefly flicker at a > 5Hz rate.  Under normal circumstances, this indication shall only occur after the 
MCU is programmed.
