The Installer will need to look for LOS, granted some customers are pretty smart and can figure it out, but in any case the Installer will need to confirm the LOS for either WA or EA, dont just asume you have LOS, thats where alot of people make misstakes. LOs is more or less a south western part. for WA and for EA more of a south eastern part. this is why the CSC asks " Do you have a clear view of the southern sky" More detail they should get into, but what they really mean is for east to west in the southern area.
j25a- dont cancel anything, if the installer is doing his job right , he can cancel the EA w/o and have CSC add the WA code to the w/o, which will set you up for the WA install. grants of course you have LOS.
One fot the first things a Installer should do is always check for LOS. He or she should come to the door, " good morning or afternoon. I am so an so from whatever I am here to install for you today, but before we get start would you like to follow me around. and look for line of site.
maybe not in that format but something to that detail.
any upgrade I go to I look before I even talk to anyone, unless the dish is behind a gate with a big scary man eating dog. then i got inside. lol
but installs can be painless to both installs and customers, be less picky and most installer will do a great job, unless you happen to get one that doesnt care, which "warning" there are some out there.
just the other day I had one install a 4 room, hd install for WA 1000.2, I found 2 places where to put the dish, one being the hardest of the 2 installs and which would have me running more cable, " I would have had to run all 4 rooms, RG-59 cable in home, installers shouldnt be using this. the second of which would have had me using less cable and the install would have nearly been unseen as far as the cable goes. but the customer wanted her husband to be there , he in her words" very picky" but she liked the second install idea.
in the end we resch the job for this coming weekend, I spent 2 hours explaining to her and her son what I need to do and and how I could do it,
I always confirm everything with a customer before, unless the customer says" i dont care, your the yech not me, just make it look good" then I will do my best to make the job go easy for us both.
Less picky in the business means better installs. for the most part.
