Apparently, you need a computer or something so you can watch the instruction video because no where in any instructions does it discuss this "Serviceman" procedure. Honestly, how in the hell would one be expected to remember all that with no instructions? The only way to do that is to have a computer......and internet......on your boat wherever that may be to do the procedure correctly. Each passing day is more stupidity.
Let me add to this. The only way to get instructions on the "Serviceman" procedure is to watch a YouTube video. So, you need to have the ability to watch that video on the boat. Since there is no internet near my boat, that means I have to watch it on the phone but apparently the video is private meaning I cannot find it unless I already have the web address. So now, since I can't save that web address on my phone, I have to write it down and take it with me and hope that I can get enough cell service to watch a stupid video for instructions that I can't get anywhere else.
