Led panel colour temperature

[Servicem4]

I recently bought a set of led panel to replace my old bulbs.

What I didn't know is the following: the panel does switch between colour temps.

Power panel on: cold white.
Off
Again on: warm white.
Off.
Again on: neutral white.
Off.
Again on: cold white and so on.

I thought the panel would save the colour temp if I let it stay on for more then 30 secs but this model deosnt save the temp.

My question: can I set it permanently to a certain colour? How?
