Clock Setting:

“Set Clock” allows you to set the timekeeping mode and the time of day.  Timing modes may be 
changed without affecting the time of day, so it is possible to switch between seconds and hundredths
of a minute, or change the precision “on the fly”.  (Note: If you intend to switch between 12 and 24 
hour time, please set the clock initially to 24 hour time.)

The clock is always set at the top of a whole minute.  Use 

  

 

switch to set the hours and minutes to 

the next whole minute.  As your official time source (official clock or WWV receiver, for example) 
reaches that time, press HOLD to set the clock.

Bump Clock:

If the time is off by a fraction of a second after setting, you may use the “Bump Clock” feature to 
synchronize it.  When selected, this mode displays the clock, and the 

  

 

switch advances or retards 

the clock a fraction for each operation.  When the clock is synchronized with the official source, use 
the HOLD button return to normal operation.
