shimano ep8 starting button

[echarry]

Hi all,

Can someone clear something up for me. Is the Shimano On/Off button meant to stay illuminated when the bike is switched on and in use?

My button is working at the moment when powering the bike on and off, but the green light fades out a few seconds later after the bike has been turned on.

Just wondering whether it’s meant to stay illuminated during the whole use of the bike or if the battery is dying, hence the light fading out.

Thanks,
