indicates safety critical compo-
nents. For continued protection
against risk of fire, replace only with
same type and rating fuse(s). To
reduce the risk of electric shock,
leakage-current or resistance mea-
surements shall be carried out

lated from the supply circuit) before
the appliance is returned to the cus-
tomer.
The DC voltage is an actual reading
measured with a high impedance
type voltmeter with a cassette
X13-A/5
-CN3 loaded at playback mode. The
measurement value may vary
3/6
depending on the measuring instru-
C
ments used or on the product. Bias
circuit DC voltage is measured
