. The beginning of the desired selection is reached
when the ( Kk , PPL ) buttons are pressed. The
time for reaching the beginning of a selection
should be about 2 seconds.
. Turn the anti-shock switch off, and apply light
shocks to the sides and top of the set. At this time
the display should change correctly and no skip-
ping should occur. Then when a stronger shock is
applied, the display may jump and sound may
skip, but operation should subsequently be normal.
