LINE VO GE SELECTION AND FUSE
SWITCHING LINE VOLTAGE SETTING
ln order to remove the fuse, turn the fuse cap located
on the line voltage selector switch in the direction
indicated by an arrow. Then remove the fuse plug
from the unit. Put the fuse plug back so that the proper line voltage marking can be seen through the
cut in the edge of the plug.
Whenever the set position of the selector switch is
changed, check the rating of the fuse. A 1-ampere fuse
is to be used for either 220V or 24OY operation and
2-ampere fuse for any of 110V, 117V, or 130V
operation. lf the rating of the fuse is proper, install
the fuse in the fuse cap.
FUSE REPLACEMENT
When the fuse is blown, remove the fuse cap and
reolrce the fuse with a nerry one.
AND FUSE
HIGH-PERFORMANCE FM TUNER
An FET (field-effect transistor) is used in the radio-frequency amplifir to attain a high
sensitivity and selectivity. Further, four lCs (integrated circuits) are used for the
intermediate frequency amplifier to eliminate interference and noise.
BUILT-IN EXCELLENT FM MPX CIRCUIT
This wvitching circuit having excellent separation and frequency response is built in for
reproduction of reality music.
