Having bought a pre-owned Sony FM stereo tuner through eBay, it came without any manuals. It soon became clear that to get the best from this excellent tuner I needed a decent manual because much of the operation was not intuitive to a newboy to hi fi like me. I managed to download the official Sony multi-lingual manual from Owner-Manuals.com with no problem at all - a really quick and easy service. I'm very glad I did because I found out all the operations of the tuner and was then able to not only set it up quickly but also to get much more from it that poke-and-hope trialling would ever achieve. In my book $4.99 very well spent.
This manual is immaculate in it's accuracy. Everything is written very clearly and easy to understand. Written by a professional who wants to convey a clear and easy to understand message!!

Cleaning and maintenance
Check from time to time the door seal and eliminate eventual possible objects that could be trapped in the fold.
The pump should be inspected regularly and particularly if the machine does not empty and/or spin the machine makes an unusual noise during draining due to objects such as safety pins, coins etc. blocking the pump. Proceed as follows: Disconnect the appliance. If necessary wait until the water has cooled down. Open the pump door. Place a container close to the pump to collect any spillage. Release the emergency emptying hose, place it in the container and remove its cap. When no more water comes out, unscrew the pump and remove it. Always keep a rag nearby to dry up spillage of water when removing the pump. Remove any objects from the pump impeller by rotating it. Put the cap back on the emergency emptying hose P1097 and place the latter back in its seat. Screw the pump fully in. Close the pump door. 72
