6. HOW TO OPERATE THE CLOCK
The three buttons have the following functions:
SET: Exit tube test routine on cold power-up;
Show date;
Set: time, date;
Enter configuration menu;
ADJ: Call WWVB / DCF / MSF;
Adjust: time, date, alarm time, configuration parameters;
ALARM: Set alarm time; snooze; cancel snooze/alarm;
Entering configuration mode:
The principal settings of the clock are stored in flash memory – your
preferred configuration is stored even after powering off the clock for
extended periods. To access the configuration mode press and hold the
‘Set’ button. After 2 seconds the seconds will become highlighted.
Continue holding the button a further 2 seconds until the clock displays
in this format:
00-XX-
99.
The ‘99’ in the seconds digits tells you that you are in the
configuration menu.
In configuration mode the hours digits diplay the current parameter
being adjusted, and the seconds digits display the current value stored
against the parameter.
For each parameter, and referring to the table below, scroll through the
range of possible values by pressing the ‘ADJ’ button. When the desired
value has been reached, move on to the next parameter by pressing the
‘SET’ button. When the last parameter has been set, pressing ‘SET’ one
more time will revert the clock back to time display mode. The first
parameter (0) cannot be changed as it is the software revision number.
It will show for several seconds and then move to parameter 1.
In all correspondence on support issues, please quote the board type,
revision date and software version.
