Sony RX10 MK 111 and captured timer kit

Hi purchased the above camera and wireless remote recently of which I am very happy with, however I can’t seem to get the video aspect to work via the remote and it appears I need to change the movie function button to operate via the shutter button but again not sure how I can do this, any ideas please?

You can download the manual for this camera manual here https://www.sony.com/electronics/support/res/manuals/4591/45916911M.pdf but it is also possible to ask a question in the box at the top. There are answers available but I don't know this camera so I am unable to reproduce the answers - they will mean more to you (hopefully).

Hi thanks for that and I will troll thru the manual, I have a sneaky idea the change of the movie function button can only be done on the MK 4.
The remote is called a Hahnel Captur timer kit as I did not describe it very well before. If anyone else has had this problem I would appreciate your advice.
