For the flags value the MSB bit is the PRF, the MSB -1 is the LUF bit,
and the two LSB bits are the LCI bits.
The separators in the string may be a full stop, colon, comma, or a
space. The second string may contain any printable ASCII character
except ' " ' or ' ' '. Its length is at most 20 characters.

Quote:
The clock is set automatically during ACMS
(Automatic Channel Memory System) when your
VCR detects a channel that broadcasts a
Teletext signal. If the broadcast signal is weak
the clock will not be set and will require setting
manually.
