CAUTION: For continued safety, replace safety critical Patlaaaeg
only with manufacturer's recommended parts (refer to parts list). A\ indi-
cates safety critical components. 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 measurements shall
be carried out (exposed parts are acceptably insulated from the supply
circuit) before the appliance is returned to the customer.
The DC voltage is an actual reading measured with a high impedance
type voltmeter with a cassette loaded at playback mode. The measure-
ment value may vary depending on the measuring instruments used or
on the product. Bias circuit DC voltage is measured while in the record
mode.
