• Your weather station will search for the signal each 3 minutes every hour automatically
until it is connected.
Note: After replacing the sensor battery, you need to press and hold the CH button of the
station to receive again.
Atomic time
A) After 3 minutes reception of the signal from the outdoor sensor, the device will begin to
search for WWVB signal automatically to set the time and date. At this time, the radio
tower begins to blink on the display next to the time and the screen dims to prevent
interference with the WWVB signal, which takes about 7 minutes.
B) The atomic time signal icon will blink while searching. The tower icon will be solid
after successful reception.
C) If reception fails after 7 minutes, the radio tower will disappear. Please set the time
manually. The device will reattempt reception for the radio time signal every 1 hour until
the WWVB time is received. -- It’s only for the first use or Reset within 24 hours.
D) If the reception attempt still failed after 24 hours (from power on), the device will search
for the WWVB time signal at 1:00AM, 2:00AM, 3:00AM, 4:00AM and 5:00 AM every day.
E) If the reception attempt is successful, the radio controlled symbol will appear
permanently on the display and the correct time and date will be set automatically.
F) After successful reception, the atomic clock weather station will search for the WWVB
time signal at 1:00AM, 2:00AM, 3:00AM, 4:00AM and 5:00 AM every day.
G) The default time zone is PST, if you need to select the time zone that matches your
location, press and hold the button to exit from WWVB signal search mode, then
refer to Next chapter “Setting the basic data” to set the time zone and time.
Important:
During WWVB signal searching, only the SNOOZE/LIGHT and button can work, other
buttons are disable and the backlight will turn dark ( in order to maximum avoid the
electromagnetic interference). lf you want to carry out other operations, press and hold the
button to exit this process.
Signal reception is normally better at night and when the weather is clear. In general, the
atomic signal takes 2-5 days to synchronize, so it’s necessary for the first time using to set
the time and date manually after power on.
