Setting the Daylight Savings Time Feature
The Daylight Saving Time feature allows you to instruct the DX-120 to automatically switch the system clock to coincide
with Daylight Savings Time changes.
When enabled, the DX-120 automatically changes the system time at the start
and end of the Daylight Saving Time period (i.e., the spring and fall).
When turned off, the system does not make a
time change to correspond to Daylight Savings Time.
NOTE
The DX-120 uses information provided by Astronomical Application Department of
U.S. Naval Observatory to determine when to make these time changes.
