Operation to reset

The microcomputer may fall into malfunction (impossibility to oper-

ate, 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 condition.

Press the "POWER" key while holding the Stop (7) key of

the CD section pressed, to switch off the power, and then

switch the power on again after a few seconds.

÷Please note that resetting the microcomputer clears the contents

stored in and returns and to condition when it left the factory.

ponents. 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 resis-

tance measurements shall be carried out (exposed parts are acceptably insulated

from the supply circuit) before the appliance is returned to the customer.

CAUTION: For continued safety, replace safety critical compo-

nents 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-cur-

rent 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.

indicates safety critical com-

ponents. For continued pro-

tection against risk of fire,

replace only with same type

and rating fuse(s). To reduce

the risk of electric shock,

leakage-current or resis-

tance measurements shall

be carried out (exposed

parts are acceptably insulat-

ed 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 volt-

meter with no signal input.

The measurement value

may vary depending on the

measuring instruments used

or on the product.
