Settings related to the device itself such as display parameters, colors, time, password protection and reset of all

settings.

Parameter

Description

 6.3.1. Date and time

PLA44 corrects internal clock according to NTP servers while it is connected to Internet. NTP time synchronization
has always priority above the manual clock settings. Clock synchronization by NTP is fully automatic and there is no

need to set anything. 
The selection of closest NTP server is adjustable in software PMS. For the finding the closest NTP server refer to the
following link 

http://support.ntp.org/bin/view/Servers/StratumOneTimeServers

.

Parameter

Description

Daylight start

Beginning of the summer time season

Daylight stop

End of the summertime season

Daylight offset

Time shift for summertime season

 6.3.2. Reset

Reset device to the factory settings. All settings including communication interface configuration will be erase and set

to the factory settings.
