Issue Description

In some site, customer can't use remote control the terminal, result in conference can't be continued. Through analysis, we found the reason is the light of conference effect infrared transmitting. 

Alarm Information

Press button of remote control, but no respond of terminal.

Handling Process

1. This remote control can work in other room. So,  remote control is ok.
2. We turn off the light of this room, and this remote control can work.
3. For ensure which part of lighting effects the infared of terminal, we send ballast of lighting to HQ, and they so a test, the result tell us it is not ballast problem, it is lighting's. Because of factory design are different, in different light, the effect to infared is different. And we give customer some suggestion about conference fitment

Root Cause

1. Maybe remote control broken or no power.
2. Maybe infrared recieve interface of terminal is broken.
3. Maybe environment effects.


For conference fitment, we have some suggestion:

Lighting: We recommend using diffuse reflectance as the main lighting of lamps. Non-diffuse reflector lamps, should pay attention to the placement of the fixtures and shielding angle to avoid discomfort glare.
Ballast:  Electronic ballast. Lumen coefficient (μ) ≥ 0.95, power factor ≥ 0.96, no screen flash, no hum, compliance with electromagnetic interference (EM) Electromagnetic compatibility (EMC) standard.
