2. 

After 15 minutes both the Indoor and Outdoor areas on your clock should have a 
temperature showing. If not, remove both sets of batteries, wait 15 minutes and repeat step 
one. 

3. 

After the clock receives the outdoor temperature the WWVB time code reception will 
automatically start. This reception typically takes between 5-10 minutes in good conditions. 
If after 15 minutes the WWVB time has not been received, use the 

“SET”

 key to manually 

enter the set-up mode and change either the time or date in order to activate the WWVB 
reception (see manual settings below). The clock will then automatically attempt to receive 
the WWVB time from 12:00 am through 6:00 am each day (attempts WWVB reception 
every full hour within this time frame). When this is successful, the received time will 
override the manually set time. The date is also updated with the received time (Please 
refer to notes on “

Radio controlled time

” and “

Manual time setting

”). 

4. 

After the time signal has been received or the search mode has been manually stopped the 
indoor temperature will be displayed. 

 

Note

When changing batteries in either of the units, ensure that the batteries do not spring free from 
the contacts. Always wait at least 15 minutes after removing the batteries before reinserting, 
otherwise start up and transmission problems may occur.
