Resetting the Microcomputer
The microcomputer may malfunction (unit cannot be operated,
or shows an erroneous display) if the power cord is unplugged
while the power is ON, or due to some other external factor. If
this happens, execute the following procedure to reset the
microcomputer and return the unit to its normal operating
condition.
•Please note that resetting the microcomputer will clear the con-
tents of the memory and returns the unit to the state it was in when
it left the factory.
With the power cord plugged in, turn the POWER key
OFF. Then, while holding down the ON/STANDBY key,
press POWER.

CAUTION: For continued safety, replace
safety critical components only with manu-
facturer's recommended parts (refer to
parts list). indicates safety critical compo-
nents. For continued protection against risk
of fire, replace only with same type and rat-
ing fuse(s). To reduce the risk of electric
shock, leakage-current or resistance mea-
surements shall be carried out (exposed
parts are acceptably insulated from the sup-
ply circuit) before the appliance is returned
to the customer.
The DC voltage is an actual reading mea-
sured with a high impedance type voltmeter
with no signal input. The measurement
value may vary depending on the measur-
ing instruments used or on the product.

CAUTION: For continued safety,
replace safety critical components
only with manufacturer's recom-
mended 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 no signal input.
The measurement value may vary
depending on the measuring instru-
ments used or on the product.
