General

Digital clock is for indoor application with time display that has 4 digits and colon as time.
The digits consist of 7 segments.
The Digital clock can be configured to show the time/date/temperature alternately in 0-
25sec intervals. Temperature sensor is not included. It is an option.
The clock is prepared for time synchronization by Network Time Protocol (NTP) from an NTP
server. If the connection to the NTP server is lost the clock will continue to run on the built-
in time base.
Configuration of network settings, light intensity and other parameters is done via a WEB-
browser.
The factory default setting for the IP address assignment is DHCP with fallback IP address
192.168.3.10. Please note if default settings are used no configuration is needed.
If the function is activated in summer and winter time, this takes place on the last Sunday in
March and the last Sunday in October, respectively.
The clock has adjustable light intensity.
If power failure occurs the display is turned off. An internal clock counts the time for approx.
48 hours.
After power failure the display is turned on and it will show bars until it is synchronised by a
NTP server. The colon will flash when time from the NTP server is accepted.
