Y
and
BR
can be pressed to switch
through the
SET
menu.
The setup program is exited by pressing the
BR
key. The standard frame reappears.
The changeover dates for daylight saving time are to be entered for coun-
tries which change their time zone during the year.

Difference Time Europe (CET)
The operational sign indicates the direction in which the local time differs from the world
time:
'+'
Corresponds to East of the Null Meridian (Greenwich)
'-'
Corresponds to West of the Null Meridian (Greenwich)
Since most countries of the world count their time offset in whole hours, the input is also in
one hour steps. The difference time may be up to ± 14.00h.
e.g. + 05:00 or - 11:00
However, some countries also use smaller time intervals. Therefore it is also possible to in-
put the data in one minute steps:
e.g. + 05:30 or - 08:45
The time offset always relates to the
local standard time (winter time)
,
even if commissioning or input of the time offset takes place during daylight
saving time.

The time offset of two hours is
made up of
+01:00h time offset and
+01:00h for the daylight saving
time offset (changeover points of
time must be set for this purpose).
