Alkaline batteries are recommended for use in both units. Avoid using rechargable
batteries.
NOTE: Do not set the clock until the outdoor temperature is displayed.
1. Place batteries in the outdoor transmitter first, then into the atomic clock. DO NOT
PRESS ANY BUTTONS FOR 10 MINUTES.
2. After the 10 minutes both the Indoor and Outdoor areas on your clock should have a
temperature showing. If not, remove both sets of batteries, wait 10 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 10 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:
In the event of changing batteries of the unit ensure that the batteries do not spring free from the
contacts. Always wait at least 10 minutes after removing the batteries before reinserting, otherwise
start up and transmission problems may occur.

segments will light up briefly before displaying the information for time, date, indoor and outdoor
temperatures.
