This 9-byte data record is similar to Clock #I, as
shown above. However, the On-/Off- Timer and
Sleep function can be controlled in this record.
Note that, in most cases, you will only need to

Read Flags Data
The Read Flags command retrieves the (first) 3
Flag Bytes of the Status Data. The receiver re-
sponds to the&& Flags command by returning the
Flag Bytes described on the preceding page, plus
two bytes with the constant values of 08h and 41h
(in that order), as shown here:
