extension, e.g., “NBG.bin”. The upload process uses HTTP (Hypertext Transfer Protocol) and may
take up to two minutes. After a successful upload, the system will reboot.
Click Maintenance > Firmware Upgrade. Follow the instructions in this screen to upload
firmware to your NBG.

Time Zone Setup

zone and Greenwich Mean Time (GMT).
Daylight Savings Daylight saving is a period from late spring to early fall when many countries set their
clocks ahead of normal local time by one hour to give more daytime light in the evening.
Select this option if you use Daylight Saving Time.
Start Date (mm/
dd)
Configure the day and time when Daylight Saving Time starts if you selected Daylight
Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time starts in most parts of the United States on the first Sunday of
April. Each time zone in the United States starts using Daylight Saving Time at 2 A.M.
local time. So in the United States you would select First, Sunday, April and select 2 in
the o'clock field.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of the
time zones in the European Union start using Daylight Saving Time at the same moment
(1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March.
The time you select in the o'clock field depends on your time zone. In Germany for
instance, you would select 2 because Germany's time zone is one hour ahead of GMT or
UTC (GMT+1).
End Date Configure the day and time when Daylight Saving Time ends if you selected Daylight
Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time ends in the United States on the last Sunday of October. Each time
zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So in the
United States you would select Last, Sunday, October and select 2 in the o'clock field.
Daylight Saving Time ends in the European Union on the last Sunday of October. All of the
time zones in the European Union stop using Daylight Saving Time at the same moment
(1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday,
October. The time you select in the o'clock field depends on your time zone. In
Germany for instance, you would select 2 because Germany's time zone is one hour
ahead of GMT or UTC (GMT+1).
