Smart meter installation

I have just had a smart meter installed by a Siemens engineer and as he did not connect the meter to my wi if I looked for how to connect . For some reason the instructions on line don’t fit with the smart meter installed. As an example the instructions state that when entering the wi fi password the user should press menu ok after every entry and press the arrow to toggle between upper and lower case letters. The display on my meter allows all of the Wi-fi password to be entered without pressing ok.and presents a keyboard which allows the user to choose upper or lowercase before each entry. Several of the other instructions don’t apply. In settings as an example access to wi fi is by pressing the Wi-fi icon in settings . Can I suggest the on line instructions are modified or made specific to the type of meter.

No point in connecting to WiFi, it doesn’t do anything yet,
