9.2. Cannot Delete
Take the steps outlinedin<2> Check the Data Transmission BetweenIC 4 and IC 9 of 9.4.
Confirm that the pulse characteristics change inIC 9 pin22 (/CE) and pin3 (R/B) <RR-QR100> /
pin7 (R/B) <RR-QR200> during deleting.
Whendeleting one file alone = change during period of approximately50 ms.
Whendeleting all files = change during period of approximately200 ms.
