Manually opening motorized valve

[Gossamer]

Hi.
I keep seeing people talk about manually opening motorized valves on CH systems before draining and refilling.
I can't see on mine how to do that. Its a Honeywell Smartfit 3-way. there's a grey lever on the front but its motorized and moves left / right when it runs. Cant see any others on it.

The valve actuator incorporates a combined position indicator and manual lever. The lever indicates the ball position. The lever should be placed in the FILL/VENT position for system filling and venting by depressing and rotating the manual lever.

The FILL/VENT position is in the centre, it says FILL/VENT in raised letters.

Thanks stem.

I can't find a manual lever as such. Or is the grey lever on front also a manual lever which can be depressed and moved manually? I don't want to break it!

I have read that already but didn't find it that clear. I'll have a tinker later.
