LASER BEAM CAUTION LABEL




When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of a laser
may be recceived.


PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electricity.
Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement,
its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire, etc. to
protect the laser diode from damage by static electricity.
And also, the LSI and IC are same as above.

                        If the socket outlets in your home are not suitable for the plug supplied with this
                        unit, the plug must be cut off and an appropriate one fitted.

                        The plug severed from this mains lead must be destroyed as it is hazardous if
                        inserted into a live socket.

                        IMPORTANT
                        The wires in this mains lead are coloured in accordance with the following code:
                        BLUE: NEUTRAL
                        BROWN: LIVE
                        As the colours of the wires in the mains lead of this unit may not correspond
                        with the coloured markings identifying the terminals in your plug, proceed as
                        follows:
                        The wire that is coloured blue must be connected to the terminal in the plug
                        which is marked with the letter N or coloured black.
                        The wire that is coloured brown must be connected to the terminal which is
                        marked with the letter L or coloured red.

                        Do not connect either wire to the earth terminal which is marked by the letter E
                        or by the safety earth symbol    or coloured green or green-and-yellow.

                        Use a 5A fuse which is approved by ASTA or BSI to BS1362.
                        Always replace the fuse cover after changing the fuse.
