It figures ...
During my time as a Customer Service Tech at Panasonic I was constantly reminded of this by customers who wanted to know how to work the phones and digital cameras.
My personal viewpoint is that while it may be nice to clip on all kinds of tech wizardry, more time needs to be devoted to make sure that the device actually does one main thing right.
If it's a phone, make sure the phone works as a phone, if it's a camera, make sure that it can take a photo.
Above all things make sure that your manual is readable and understandable and is not filled with fluff but with good information.
Both Panasonic & Siemens corps needs to figure the former out.
