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.

Maintenance and Cleaning
Before any maintenance or cleaning can be carried out, you must DISCONNECT the hob from the electricity supply. The hob is best cleaned whilst it is still warm, as spillage can be removed more easily than if it is left to cool.
The Hob Top
Regularly wipe over the hob top and the aluminium frame using a soft cloth well wrung out in warm water to which a little washing up liquid has been added. Avoid the use of the following: - household detergent and bleaches; - impregnated pads unsuitable for non-stick saucepans; - steel wool pads; - bath/sink stain removers.
The pan supports are dishwasher proof. If necessary, remove stubborn stains using a paste cleaner. Never use steel wool pads or acids.
The burner caps and crowns can be removed for cleaning. Wash the burner caps and crowns using hot soapy water, and remove marks with a mild paste cleaner. A well moistened soap impregnated steel wool pad can be used with caution, if the marks are particularly difficult to remove. After cleaning, be sure to wipe dry with a soft cloth. The cap and crown of each burner are secured with two screws. To separate the two pieces, lift the crown, turn it upside down, then undo the two fixing screws as shown in fig. 3. After cleaning, reassemble the two parts and refit the cap on its correct position on the burner.
