VII. TIME 

SETTING

There are two methods by which the time and date can be set:   
A) Automatically via WWVB reception, or 
B) Manually. 

A.  WWVB (Remote Control Time) 

This method requires you to do nothing, except wait for the signal to be received, and to select a 
time zone.  Reception usually takes approximately 10 minutes during optimal conditions. The best 
conditions for reception is at night, between midnight and 6:00 am—when there is less atmospheric 
interference. To keep your time as accurate as possible, the indoor weather station conducts a 
WWVB search every night between these hours, and overrides any manually set time. The WWVB 
tower icon (appearing in the TIME LCD) will flash when a signal-search is in progress and a signal 
is being received, and will remain steady when the signal has been received.  If the WWVB time has 
not been received after 15 minutes of battery installation, you may manually set the time or leave the 
time function alone (reception will occur regardless). 

B.  MANUAL TIME SETTING

Note:

  When in the 12-hour format “P.M.” will appear to the left of the hour in the time LCD 

between the hours of noon and midnight. 

Note:

  Reception of the WWVB signal will automatically set the time. The reception of the 

signal will override any programmed time. 
 
 
 
 
1.  The hours digits will flash in the TIME LCD. 
2.  Press and release the 

MIN/MAX/+

 button to advance or the ALARM/- key to decrease the 

hours.
