• In the interests of user-safety the set should be restored to its
original condition and only parts identical to those specified be
used.
These new model MD-SR505E/70H/70W have almost the
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
refer to the already issued service manual for MD-SR50H/
50W/60E/60W(S2006MDSR50H/) as well as this service
