 in a file that (usually) uses the system model 

name with a “*.bin” extension, e.g., “NBG4615.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 NBG4615.

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 type 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 type in the o'clock field depends on your time zone. In 
Germany for instance, you would type 2 because Germany's time 
zone is one hour ahead of GMT or UTC (GMT+1).
