TO INSTALL AND REPLACE BATTERIES IN THE ATOMIC CLOCK 

The Atomic Clock uses 2 x AA, 1.5V batteries.

To install and replace the batteries, please follow 

the steps below:

1.  Insert finger or other solid object in the space at the bottom center of the battery compartment 

and lift up to remove the cover. 

2.  Insert batteries observing the correct polarity (see marking). 

3.  Replace compartment cover. 

DO NOT SET THE CLOCK. 

TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE 

TRANSMITTER 

The transmitter uses 2 x AA,1.5V batteries. To install and replace the batteries, please follow the 

steps below: 

1.  Remove the cover. 

2.  Insert the batteries, observing the correct polarity (see marking). 

3. 

Replace the battery cover on the unit.

Alkaline batteries are recommended for use in both units 

SETTING UP: 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 5 minutes and repeat 

step one. 

3. 

After the clock receives the outdoor temperature, set your time zone using the 

manual settings below.  The default time zone is Eastern Standard Time. 

4. 

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 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”). 

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 5 minutes after removing the batteries before reinserting, otherwise 

start up and transmission problems may occur.
