What is the purpose of か in this sentence?


In my opinion, it would not function as interrogation or alternative
explanation.

Here is the sentence.

> 電源ボタンを押すと表示される電源メニューで「電源を切る」をタッチする **か**
> 、電源ボタンを電源ランプが消えるまで押し続けると、電源がOFFになります。




か means literally "or" in this instance.

It splits the sentence into the two options you have for turning off the
device.

You can turn off the device by choosing from the menu, OR you can long press
the button until the light turns off.

Also acceptable in its place would be 「又は」or「もしくは」but the latter seems more
formal, so it wouldn't be used in (what I assume to be) a user manual. and 又は
I believe is more commonly used at the beginning of the next sentence denoting
a second choice that can be taken as opposed to being used in the middle of
the same sentence.
