CLOCK BATTERY REPLACEMENT 

 
When the display begins to look dim, it is time to replace the batteries in the clock. 
 
Remarks: 

 

Do not mix old and new batteries 

 

Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel cadmium) 
batteries. 

 

For longer battery life, alkaline batteries are recommended. 

 

TROUBLE SHOOTING 

 
When your clock displayed irrelevant time, calendar or temperatures, which might be 
caused by interferences of electrostatic discharge or other wireless signal in the air e.g. 
TV, computer monitor, radios, walkie-talkie etc, press the WAVE button once, the clock 
will start receiving WWVB signal and update to correct WWVB time 
 
If  such  situation  still  persists,  press  the  RESET  button  once  to  set  the  clock  to  factory 
default  setting.  The  clock  will  receive  WWVB  signal  again  to  update  itself  to  correct 
WWVB time.
