MEASURE CARRIED OUT TO COMPLY WITH NOISE STANDARDS.

1.Model Name: SF-1016/2116/2118 (only for machines bound for Taiwan.)

2.General: The changes described below have been carried out as a measure to establish

No. : S-208

compliance with Taiwan noise standards.

3.Description: <1> A change has been carried out in the capacitors and in the resistors used in the AC

circuit PWB.
The capacitor (C204) has been changed from 0.22 µF to 6 µF.

VCFYEG2EA224M → RC-FZ0351FCZZ

The resistor (R203) has been changed from 1 MΩ to 220 kΩ.

VRD-HT2EY105J → VRD-HT2EY224J

In accordance with the changes described above, the part code for the AC circuit PWB
has also been changed.

<2> The addition of a grounding shaft and a ground wire has been carried out. (This

change has been carried out only on models SF-1016 and SF-2016.) This change has
been carried out as a measure to improve the grounding performance of the
reinforcement plate in the base plate unit.
