Setting Daylight Savings Time for model MRX-35
Enabling Daylight Saving Time
The MRX-35 is shipped from the factory with the Daylight Saving Time (DST) feature enabled (
U
using
the pre-2007 standard
U
). However, the DST feature can be disabled if so desired. The procedure for
enabling/disabling DST is as follows:
1. Insert MRX Basic Programming Card #1 Side B. The card will
stop at the Daylight Saving Time position.
2. Press the one of the buttons indicated by the programming card to
either enable or disable Daylight Saving Time.
3. Press the Next button to enter your selection. The card and
the display will advance to the Daylight Saving Time Begin
Date position. You may also press this button to advance
through all settings until the card is ejected.
Note: If
“Disable” is selected, pressing Next will eject the card.
If DST is enabled, the MRX-35 will automatically calculate the DST begin date from year to year.
However, due to the United States change, effective 2007, for the start date and end date of DST, it is
necessary to reprogram these dates for the auto-time-change to work correctly.
To manually set the start and end dates to the 2007 standard, proceed to the next section.
