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 inside battery compartment).
3. Replace the battery cover on the unit.
Alkaline batteries are recommended for use in both units. Avoid using rechargable
batteries.
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 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 15 MINUTES.
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.

7
3. Press and release the SET key to confirm the DST setting and continue to the Radio-
controlled time 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”.
RADIO-CONTROLLED TIME SETTING
1. The word ON will start flashing in the lower LCD display.
2. Press and release the +key to select radio-controlled time ON or OFF.
3. Press and release the SET key to confirm the radio-controlled time setting and continue to

2. Press and release the +key to select the desired language.
3. Press and release the SET key to confirm the language setting and enter the Manual Time
setting mode.
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.
1. The hour digits will start flashing in the upper LCD.
2. Select the desired hours by pressing and releasing the +key.
3. Press and release the SET key to advance to the minutes setting.
4. Now the minute digits will start flashing.
5. Select the desired minutes by pressing and releasing the +key. If the +key is held, the
units will increase by 5.
6. Press and release the SET key to confirm the Time setting and continue to the Year setting.
Note:
The unit will still try to 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 reception has been unsuccessful, then the WWVB
tower icon will not appear but reception will still be attempted the following hour.
WWVB time reception takes place from 12:00 am through 6:00 am each day (attempts WWVB
reception every full hour within this time frame). When the time signal is received for example at
1:00 am, the atomic clock will not attempt to receive the WWVB signal for the remaining hours
until 6:00 am. Therefore, the next signal attempt will take place between 12:00 am and 6:00 am
the next day. 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.
YEAR SETTING
The year can be selected sequentially from 2003 to 2029 and will then start over again (default
setting 2004). None of the digits of the year will be visible on the lower LCD display however the
year must be correct as it affects the day of the week display.

SNOOZE SETTING
The snooze can only be activated during alarm time for a snooze duration of 10 minutes by
pressing the SNZ key on the back of the clock.
OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the atomic clock every 1 minute. The atomic
clock will update the temperature display every 5 minutes.
The range of the outdoor temperature transmitter may be affected by the temperature. At cold
temperatures the transmitting distance may be decreased. Please bear this in mind when
positioning the transmitter. Also the batteries may be reduced in power during periods of extreme
cold temperatures.
433MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The atomic clock will receive the temperature data within 4 minutes. If the temperature data has
not been received 4 minutes after setting up (the display shows “- - -”), then please check the
following points:
1. The distance of the atomic clock or outdoor temperature transmitter should be at least 6 feet (2
meters) away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.
