Question about Measuring Tools & Sensors
SOURCE: Set the clock
You are in luck. I had to replace the batteries in my DWS-150 & couldn't find the instruction manual to reset the time. Fortunately, I remembered a while back I had the same situation & thought I might have downloaded the manual - while it was still available. Ifound I have it saved as a pdf file on my pc. Here are some excerpts:
About the Atomic Clock
The National Institute of Standard and Technology (NIST) in Fort Collins,
Colorado broadcasts the time signal (WWVB at 60kHz AM radio signal) with
an accuracy of 1 second per every 3,000 years. The signal will cover a
distance up to 2,000 miles from the source. Like a typical AM radio, your
Atomic Clock will not able to receive the WWVB signal in places
surrounded by heavy concrete or metal panels. The reception of the time
signal can be affected by mobile phones, TV, electrical appliances or other
electronic interference. To get the best performance of the Atomic clock,
please install the home receiver near a window and away from large metallic
objects. If the unit is not working properly, change the unit position. There
may be some interference at this location.

The home receiver will start synchronizing the clock after the 1st channel of
the RF thermometer is registered.
1. At normal mode, hold the “ - ” button located on the back of the home
receiver for 3 seconds to force synchronization.
2. The antenna icon will appear during the synchronization process (on the
right side of the time display).
3. If the icon disappears afterwards, radio time signal is not available at that
moment. Try setting the home receiver in other locations. Remember to
place the unit away from sources of interference such as mobile phones,
appliances, TV etc.
4. Antenna icon will appear on screen if the radio time reception is
successful. The radio-controlled clock will have a daily synchronization at 1:00 am everyday. If previous attempts of reception were
unsuccessful, the home receiver will attempt synchronization
each hour until successful.
5. Each reception cycle is minimum 2 minutes and maximum 10 minutes.
