1.0 Introduction
Due to a change in US Federal law governing the beginning and ending dates for Daylight Saving
Time, the firmware on PXL-250s (v6.3.61), PXL-500s/PXL-510s (v8.4.47), and EntraGuards
(Gold/Silver/Titanium v7.3.17 and Platinum v9.0.3) have been changed to reflect the new dates.
Beginning in 2007, Daylight Saving Time will begin (“Spring Forward”) on the second Sunday in
March. Daylight Saving Time will end (“Fall Back”) on the first Sunday in November.
As these new dates apply only within the US, there are instances where some may wish to opt out of
the automatic Daylight Saving Time adjustment. Perform the following steps to opt out of the
Daylight Saving Time firmware update.
2.0 Daylight Savings Adjust
