Hi Thanks for your reply.
The LED I am talking about is LED1 (Battery being charged(Red LED Indicator)) on the box. LED3 (Presence of hold off supply(Red LED Indicator) and LED2 (Tamper Healthy(Green LED Indicator) are fine.
I am not sure if this is how you are supposed to post a follow up or whether you are supposed to ask another question.
Thanks.
