TO INSTALL AND REPLACE BATTERIES IN THE ATOMIC CLOCK
The atomic clock uses 3 x AA, 1.5V batteries. To install and replace the batteries, please follow
the steps below:
1. Pull down on the tab at the top of the battery cover and lift up to remove the cover.
2. Insert batteries observing the correct polarity (see marking inside battery compartment).
3. Replace compartment cover.
DO NOT SET THE CLOCK.
SETTING UP:
Alkaline batteries are recommended for use. Avoid using rechargeable
batteries.
1. Place batteries in the atomic clock. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
2. After 15 minutes the indoor area on your clock should have a temperature and humidity
showing. If not, remove batteries, wait 15 minutes and repeat step one.
3. After the clock receives 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 the unit, 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
problems may occur.
