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 inside battery compartment).

3. Replace compartment cover.

DO NOT SET THE CLOCK.

SETTING UP:
Alkaline batteries are recommended for use in both units. Avoid using
rechargeable batteries.

NOTE: Do not set the clock until the outdoor temperature is displayed.

1. Place batteries in the outdoor sensor first, then into the atomic clock. DO NOT PRESS
ANY BUTTONS FOR 10 MINUTES.

2. Once the batteries are in place, all segments of the LCD will light up briefly. Following the
indoor temperature, date, weekday, and the time, as 12:00, will be displayed. If they are not
shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds
before reinserting them. Once the indoor data is displayed proceed to the next step.

3. After the batteries are inserted, the atomic clock will start receiving data sign al from the
sensor. The outdoor temperature should then be displayed on the atomic clock. If this does
not happen after 3 minutes, the batteries will need to be removed from both units and reset
from step 1 and the signal reception icon is no longer shown.

Note:
In the event of changing batteries of the unit ensure that the batteries do not spring free from the

1. The ON digit will start flashing on LCD2. Set the DST ON or OFF by pressing the + key.

2. Press and release the SET key to enter the “Language Setting“.

Note:

The DST default is “ON”, meaning that the WWVB will automatically change the time according to
Daylight Saving Time in the spring and fall. For areas that do not recognize DST changes
(Arizona and parts of Indiana) turn the DST “OFF”.

LANGUAGE SETTING

The weekdays can be displayed in LCD2 with the pre-set languages: US English=US, French=F,
Spanish=E and German= d.

1. Set the desired language for the weekday display in LCD2 by use of the + key.

2. Press and release the SET key to enter the mode “Manual Time Setting”.

MANUAL TIME SETTING

In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time can be manually set. The clock will then work as a normal Quartz clock.

Note:

The unit will still try and receive the signal every day despite it being manually set. When it does
receive the signal, it will change the manually set time into the received time. During reception
attempts the WWVB tower icon will flash. If rece pti o n has been unsuccessful, then the WWVB
tower icon will not appear but reception will still be attempted the next hour.

WWVB reception occurs daily at 12:00 am and 06:00 am. If the reception is not successful at
12:00 am, then the next reception takes place the next ho ur and so on until 06:00am, or until the
reception is successful. If the reception is not successful at 06:00 am, then the next attempt will
take place the next day at 12:00 am.

The other times WWVB reception takes place are upon setup and after manual time set exiting
mode. Reception is generally not possible during daylight hours due to the interference of the sun.
