Hi
I have just upgraded my Edge 520 Plus to an Edge 820 to gain the functionality supposedly offered by having an ambient light sensor.
I have paired my Varia RTL510 as a light and radar and set about checking it out yesterday day and night. So far I have discovered that:
1. Individual works okay, I can select "Low", "Day Flash" or "Night Pulse" for the Varia on the Edge;
2. "Auto", "High Visibility" and "Trail" do not seem to do anything, the Varia goes into Day Flash and stays in that mode day or night, dark or light;
3. The Di2 Shifters can cycle between "Day Flash" and "Low" on the Varia but skip "Night Pulse".
The RTL510 manual just says that in the three modes "Auto", "High Visibility" and "Trail" the Edge will automatically adjust the light, it doesn't say what exactly it is supposed to do. I expected it to use variations of Day Flash, Low and Night Pulse depending on the ambient light, time of day etc.
I also don't understand why the Di2 cannot select Night Pulse??
Any help appreciated.
