Note: 

 

The minutes and seconds of the digital clock cannot be manually set. It will 
receive the WWVB time from the analog clock.  

 

The time format is fixed to "12-hr" time display. "PM" will be shown in hours 
from noon to midnight. 

 

The calendar will also be updated once the WWVB signal from the analog 
clock has been received. 

 

WORLD TIME SETTING

This feature allows you to display a 2

nd

 time from anywhere in the world.  

The world time can be manually adjusted by 1 hour increments (24 hour time 
zone).

 

 

1. 

Press the Time Set key to enter world time setting. 

2. 

Press the Time Set key again to set the desired world time. Each key press 
will increase the world time by 1 hour. 

 

Note: 

 

Once the WWVB signal has been received by the digital clock, the manually 
adjusted world time will be updated.  

 

If a world time has been manually set prior to reception of the WWVB time, 
the time in the digital clock will change correspondingly with the analog clock. 

 

The calendar (month/day) will not follow the set world time; it can only be 
updated from the WWVB signal. 

 

When DST changes, the digital and analog times will set ahead or back 

one 

hour

 in accordance with the NIST signal. To maintain proper World Time, 

you may have to manually adjust the hour.
