To function properly, the digital wall clock must be started correctly using good quality alkaline batteries and the time must be set.


Section 1 - Time Display

Question 1   Display is blank

Check the polarity on your batteries to make sure they are installed according to the diagrams in the battery compartment. Also make sure that you are using a new good quality alkaline battery.

Question 2   Time is incorrect or not displaying at all
  1. If you have not yet installed the batteries or plugged in the clock and it shows a time, remove the scratch-guard from the LCD panel.
  2. This clock receives a signal from Ft. Collins, Colorado (WWVB) to set the clock to atomic time. Sometimes, due to adverse weather or atmospheric conditions you will not be able to receive a signal immediately. The best way to get a signal is to put your clock in a window facing Colorado until you see the tower icon appear.
  3. If your time is off by an increment of 1 hour, change your time zone to match your location.
