CAUTION
The year time switch only operates correctly if you observe the
following rules:
• The On year must be before the Off year,
• ON and OFF times must be specified the same in pairs, for
example:
• ON = Day/--/--, OFF = Day/--/--
• ON = --/--/Year, OFF = --/--/Year,
• ON = --/Month/Year, OFF = --/Month/Year
• ON = Day/Month/Year, OFF = Day/Month/Year
• Normally, the ON day should be before the OFF day;
otherwise, the exception described on Example 8
(
￫ section “ Example 8: Selecting a time range of two days
spanning the turn of the year (2-channel)”, page 289) on
applies.
