GETTING STARTED

-   Remove the battery door.
-   Install 3 new AAA size batteries as per the polarity information 
    marked in the battery compartment.
-   Once the batteries are installed, the full segments of the LCD will 
    be shown before entering the radio controlled time reception mode.
-   The radio controlled (RC) clock will automatically start scanning for
     the radio controlled (RC) time signal within 8 seconds.

NOTE:

If no display appears on the LCD after inserting the batteries, press the

[ RESET ]

 button by using a pointed instrument. In some cases, you 

 

 

 

may not receive the signal immediately. Due to atmospheric disturbances,

 

the best reception often occurs during nighttime.

RECEPTION OF WWVB RADIO SIGNAL                                                

-   The unit must receive the WWVB Radio Signal to automatically set 
    the time, date and day of the week.
-   The unit automatically starts the WWVB signal search after replacing or

 

    inserting batteries, as indicated by the flashing "signal tower" icon.  
-   Everyday at 2:00 am, the unit automatically carries out the 
    synchronization procedure with the WWVB signal to correct any 
    deviations to the exact time. If the attempt is not successful, the 
    "signal tower" icon will disappear from the display and the unit will 
    automatically attempt synchronization at 3:00 am. This procedure 
    is repeated automatically again at 4:00 am if necessary.
-   Each synchronization process will take between 3 to 16 minutes, 
    depending on the signal strength received. If no signal is detected, 
    the unit will automatically exit the process in 6 minutes.
-   Once the unit is synchronized successfully to the WWVB signal, 
    the "signal tower" icon will be turned on until 2:00 am of the following day.
-   The unit also conducts periodic checking of WWVB radio signals 
    at 8:00 am, 2:00 pm, and 8:00 pm. Any successful attempts to connect
    at these hours will lead to the display of the "signal tower" icon until 
    2:00 am, the following day.
-   To manually start the WWVB signal reception, press the 

[ RCC / °C/°F ]

 button. Cancel the process by pressing the 

[ RCC / °C/°F ]

 button. 

SETTING TIME ZONE

Your clock is designed to display time for different time zones. Please 
refer to the Manual Clock setting to set your desired time zone in 
the following order:
               PST: Pacifi c                           MST: Mountain
               CST: Central                          EST: Eastern
               AST: Atlantic                          NST: Newfoundland

NOTE:

After selecting the time zone, the "signal tower" icon will be turned 
off as the unit is no longer synchronized to WWVB radio signal. User 
may press the 

[ RCC / °C/°F ]

 button to re-start the synchronization 

process, or let the clock automatically carry out the synchronization 
procedures daily starting at 2:00 am.

SIGNAL STRENGTH INDICATOR                                                        

The  signal  indicator  displays  signal  strength  in  4  levels.  Wave 
segment fl ashing means the time signal is being received. The signal 

 

quality is classified into 4 types:

  No signal

  Weak signal quality           

  Acceptable signal quality         Excellent signal quality

If the RC clock receives the signal successfully, the signal tower icon 

 

 

Thank you for purchasing this radio controlled atomic clock.

The utmost care has gone into the design and manufacture of your 

clock. Please read the instructions carefully and keep this manual for 

future reference.
