Checking
the loading/sled
motor's operation
As shown
in the figure,
connect an ammeter
and a DC pow-
er supply to the loading/sled
motor (CM38),
and set the tray
open and end switches to the "off"
[open] positions.
Check that
the pickup (CM52)
moves smoothly
without

from
the
inner
circumference
of the compact
disc to.
ward
its outer
circumference
when
a DC 0.6V voltage
is ap.
plied from the DC power
supply.
The disc tray
is housed
inside and the gear (CM9) slips when
a DC 4V
voltage
is applied
from
the
DC power
supply.
Check
that the ammeter
indicates 120mA
or more
at this
time.
