Notes:
1. Master Blanking Mode has priority over Night Mode. Use to disable the clock on
weekends (eg clock is in office), or during office hours (eg clock is at home). Complete
HV shutdown to save power and tube life.
2. Night time neons mode is active when night mode is set to dim. During night time
blanking the tubes AND neons are disabled.
3. Clock is fully functional without GPS / XTERNA synchronisation. Set time manually.
4. Enter your time zone offset from the synchronisation source. Note that GPS transmits
UTC.
5. Visual effect / cathode poisoning prevention – all digits on all tubes are cycled for 10
seconds.
6. Date will be displayed each minute between 50 and 55 seconds past the minute.
7. Press ‘SET’ briefly during Night Mode to show time for prescribed period.
8. Set this parameter to ‘1’ to restore factory configuration settings. Internal operations
will then load all the original settings and restore the value to ‘0’
