Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!
I purchased a vintage Sony mixer off eBay and within the hour was able to locate and purchase the manual for it.I mean really,where else can you find a manual for a product made in 1983!? It was easy to find and purchase/download the manual I needed.I will use this site again for other equipment I have! Great site!
It`s full copy of a service manual from url http://www.philips.owner-manuals.com/PM3216-service-manual-PHILIPS.html

* You may have to enter the Call Hold feature number, "20", after pressing the Recall/ hookswitch on your single line telephone (SLT), depending on the SLT Hold Mode of your PBX. For more details, refer to "1.1.15 Call Hold" in the Feature Manual. To return to the held call before the third party joins, press the corresponding CO or INTERCOM button or press the Recall/hookswitch. By pressing the CO button corresponding to an outside (CO) line that is not being used by the conference, a proprietary telephone (PT) user can exit from the conference, leaving the other 2 parties connected unless they are both on outside (CO) lines. If the other parties are both on outside (CO) lines, they will be disconnected.
