Oxygen warning light

[Neal]

Hi,
I've recently started getting the oxygen CWP illuminate on flights and I'm not quite sure why it's happening so frequently.

The first time, I descended to a safe altitude and once landed, shut the aircraft down, and then restarted a flight. I just assumed I had done something wrong and by restarting, the system would be 'repaired'.

I'm still getting occasional warnings but I can't track the issue. The canopy is closed and locked, the oxygen level is adequate, the switches are on, both front and rear and the indicator confirms airflow (didn't manage to capture it in the screenshot, but it was on). The cabin pressure seems correct for the altitude.

Any ideas?
