SUBJECT
Remote controller does not works properly
REF.No. :G − A1− 057− E0
DATE :17. OCT. 2001
<CONTENTS>
Due to malfunction of sensor part of remote controller(IC3), it may does not work properly. In this case, take the following corrective countermeasure.
(Corrected set is dotted at the right side of serial No.)
<COUNTERMEASURE>
Due to the following corrective countermeasure, it prevents from the fault of sensor part by surge voltage.
1.Replace IC3 from GP1U281Y to SBX1981− 72P.
2.Add JW305 following the drawing(land exists).
3.Back solder ZENER,UZ6.8BSC following the drawing. Glue(KE− 3490) on the parts.
4.Put the dot mark at the right side of serial No. after countermeasure.
