If signal level is weak and time reception is not successful, move the unit away from any source 

of possible interference and try again in another location.  The R/C clock will attempt a daily 

synchronization at 1:00 AM everyday.  If not successful, the R/C clock will search for the time 
signal every hour.  Each R/C reception cycle lasts from 2 to 5 minutes.  To avoid interference, the 

unit will disable the other button functions during Radio Controlled Time reception.  This is not a 

defect.  Simply press the SET button to turn Radio Controlled Time reception temporarily off. 

 

To Set Clock Manually: 

In case the clock is not able to receive the time signal quickly, you can still enter the time 
manually. 

 

Set desired time zone first ( see above, Entering Time Zone) 

 

Hold the SET button for 3 seconds: Press the “+” or “-“ to adjust the setting and press 
SET to confirm the setting sequence.  The sequence is: 

Year/Month/Date/Hour/Minute/12/24hr/DST on/off/Exit 

 

DST on/off is the Daylight Saving Time function.  ON means it is enabled and OFF means 
it is disabled.  Even if we are not currently observing DST and you are a state that 

observes DST you want to make sure that it is set for ON. 

 
ALARM 

Enter the alarm setting mode by pressing and holding the ALARM button for 3 seconds.  The 

hour digit will begin to flash.  Set the required hour by pressing the “+” or “-“ buttons on the 

front of the unit.  Be sure to pay attention to the proper AM or PM setting to ensure your alarm 

will sound at the correct time.  Press the alarm button again and the minutes will flash.  Set the 

correct time using the “+” or “-“  buttons located on the front of the unit.  Press the alarm button 
again to exit the set up and return the display to the current time.  

 

Activate or Stop Alarm 

To activate the alarm you want to press and release the “+” button on the front of the unit. To 

stop the alarm, press the ALARM button to stop the alarm for 24 hours.  The alarm can also be 

silenced by pressing the “+” button on the front of the unit with the bell symbol over it.  This will 
turn off the alarm until you press this button again to reactivate it. 

 

SNOOZE/LIGHT 

Press the snooze/light button to enter the SNOOZE mode.  The alarm will sound again in 8 

minutes.  A green backlight will also illuminate for 3 seconds each time this button is pressed. 

 
Min/Max Memory 

Press the “MEMORY” button to view the maximum temperature and humidity values for both in 

indoor and outdoor.  Press again to view the minimum values.  After 5 seconds the display will 

return back to the present readings.  The Min/Max button will be cleared every night at midnight. 

 

Temperature & Humidity Trends (Outdoor Temperature & Humidity) 
If the temperature increases by more then 1 degree or the humidity increases by 3%, the trend 

arrow will point up showing a rising trend.  If the temperature change is less than 1 degree or 

the humidity changes less than 3% the trend arrow will be level showing a steady reading.  If the 

temperature drops more than 1 degree or the humidity drops 3% the trend arrow will point down 

showing an falling trend.  Trend icons update every hour. 
 

Moon Phase 

The unit will display the current moon phase according to the time and calendar. All phases will 

flash once in sequence but the current moon phase will remain displayed for 5 seconds.  This 

feature requires no adjustment on the user end.
