• In the interests of user-safety the set should be restored to its
original condition and only parts identical to those specified be

same structure as the former model MD-SR50H(S) except for
some outer parts, the colour of the main unit has changed from
black to champangne green, and so only these parts are here
described. When servicing the MD-SR505E/70H/70W, please
