A lot of the Ebay sellers of catalogue return phones DONT include the instructions with the phones, this guide will help you get manuals on line for free
DST dont sell this category of pre used phone (we specialise in NEW phones at rock bottom prices) but we are a customer focussed seller and as such we submit this information.
Some sellers will (eventually) send you a PDF on request, others will try to charge you for something you should already have!
Either way its a pain waiting and you should not have to.
BT phone manuals for current and older models are on the BT.com website put /userguides after the URL (we cannot put the URL on here but the BT site is an obvious URL)
SIEMENS use the word gigaset in the url ie gigaset.siemens again all manuals are available free for download as are the software upgrades.
PANASONIC from the Pan website select customer support and then download centre - most manuals are inc (we have all Pan paper manuals if required).
PHILIPS Same as Pan - from the UK site select customer support most are available
Hope this helps a bit - will add more when I get time
Then again you could just buy new complete kit at a bargain price - shipped FAST by a PRO dealer offering REAL guarantees !!
