Dust Alert

For some reason my GX-20 will not let me select the dust alert to show me that white image to see if there's any dust on my sensor.
I have a lens on, full battery, empty memory card.
I have checked the manual and it is more or less useless.
Can anyone help?

Thanks.

If you fit a non-AF lens or set the camera to MF, you can't use Dust alert because this operation will try to set the lens to infinity and can't do it with a non-AF lens.

Thank you.
I had it switched on manual focus.
Why doesn't it say in the user manual that it needs to be in auto focus?

I got a reading and the sensor is clear. So what confuses me now is that with two different lenses I get the same identical dust pattern.
The dust might have been on the sensor but I ran the sensor shake a few times whilst pointing the camera to the ground last night. It looks like that has ridden it of the dust.

Sansung's user manual is like an improved version of the English camera manuals for Japanese cameras in the 1980s: these were often incomprehensible, even if the product was respectable.
