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

Getting Started
Connecting Headphones
The HP 237R features two headphone jacks. This allows two people to listen through headphones simultaneously, making it very useful for lessons and when performing piano pieces for four hands. Additionally, this allows you to play without having to worry about bothering others around you, even at night.

1. Turn the volume all the way down by using the [Volume] slider. 2. Plug the headphones into the Phones jack on the lower-left panel of the HP 237R. 3. Use the [Volume] slider to adjust the volume of the headphones.
This switches off the HP 237R speakers. Sound will be heard only through the headphones.
NOTE
Please use stereo headphones.
q Precautions to take when using headphones
- To avoid damaging or severing the headphone cord, be sure to handle the headphones by holding the phones themselves, and grasping the plug and not the cord when pulling the headphone plug. - Connecting the headphones when the volume of connected equipment is turned up may result in damage to the headphones. Connect the headphones only after turning the volume down completely. - Listening at excessively high volume levels will not only damage the headphones, but may also cause hearing loss. Listen at appropriate levels.
