When replacing batteries...

Leave the batteries out of the clock for at least ten seconds before inserting new batteries. Follow one of the three methods below.

  • Install the clock's batteries between 39 minutes past the hour and 6 minutes after the next hour. It should set the time right away if it's near a transmitter. 

  • Install the batteries at any time of the day. The clock will set its time at the next 39 minutes after the hour.

  • Power cycle the nearest transmitter. It will then broadcast for 8 consecutive hours and clocks will set immediately on power-up.
