Operation to reset
The microcomputer may fall into malfunction
(impossibility to operate, erroneous display,
etc.) when the power cord is unplugged while
power is ON or due to an external factor. In this
case, execute the following procedure to reset
the microcomputer and return it to normal con-
dition.
Unplug the power cord from the power out-
let and, while holding the stop key de-
pressed, plug the power cord again.
÷ Please note that resetting the microcomputer
clears the contents stored in it returns it to con-
dition when it left the factory.

CAUTION: For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to
parts list). indicates 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 measurement value may vary depending on the measuring instruments used or on
the product. Bias circuit DC voltage is measured while in the record mode.
