The IEM mode is active from 18:00 of weekday Monday until 06:00 of weekday Tuesday (as
indicated by the IEM STOP time of weekday Tuesday).

weekday Tuesday.
It can be, without change of meaning, any time between 18:00 and 23:59.
Similarly, the IEM mode is active from 18:00 of weekday Tuesday until 06:00 of weekday
Wednesday.
The IEM START time of weekday Wednesday has no effect as it is preceded by the IEM START
time of weekday Tuesday.
It can be, without change of meaning, any time between 00:00 and 06:00.
To avoid undesired IEM mode operation, verify:
• Date and Time (first page of parameter).
• IEM mode screen how many hours of IEM mode operation have been
selected for each day of the week.
