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.

TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE SENSOR

The sensor 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 rechargeable batteries.

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 user may 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 2 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 contacts. Always wait at least 10 minutes after removing the batteries before reinserting, otherwise start up and transmission problems may occur.

TIME ZONE SETTING

After entering the manual setting mode as described above, the time zone can be set between the +12 to –12 hour or Greenwich Mean Time (GMT) range in LCD2. To do this:

1. The time zone (LCD2) will start flashing (Default setting "-5h“). Select the desired time zone by pressing and releasing the + key.

Note: The time zones from –4 to –10 hours will be displayed with 3 characters abbreviations:

 -4 ATL (Atlantic time),  -5 EST (Eastern time; default time zone),  -6 CST (Central time),  -7 MST (Mountain time),  -8 PST (Pacific time),  -9 ALA (Alaska time),  -10 HAW (Hawai i ti me).  "GMT” will be displayed if set to GMT (0).

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

DST SETTING (daylight saving time)

1. The ON digit will start flashing on LCD1. 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 LCD1 with the pre-set languages: US English, French, Spanish and German (US, F, E, d).

1. Set the desired language for the weekday display in LCD1 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 (dist urbances, transmitting distance, etc.), the time can be manually set. The clock will then work as a normal Quartz clock.

Note: In 12 hours mode the time will be displayed with an additional “PM” for the time from 12:00 noon until 11:59.

1. The hour digits will start flashing on LCD1.

2. Set the desired hours by pressing and releasing the + key followed by pressing the SET key.

3. Now the minute digits will start flashing.

4. Set the desired minutes by pressing and releasing the + key . If the + key is held, the units will increase by 5.

5. Press and release the SET key to move to the “Year Setting”.

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 reception 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 hour and s o on until 06: 00 am, 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.

YEAR SETTING

The year can be selected sequentially from 2001 to 2029 and will then start over again (default setting 2006). Only the last 2 digits of the year will be visible on LCD2.

OUTDOOR TEMPERATURE SENSOR:

The temperature is measured and transmitted to the atomic clock every 4 seconds. The atomic clock will update the outdoor temperature display every 4 seconds. The range of the outdoor temperature sensor may be affected by the temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when positioning the sensor. Also the batteries may be reduced in power during periods of extreme cold temperatures.

915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE SENSOR

The atomic clock will receive the temperature data within 3 minutes. If the temperature data is not being received 3 minutes after setting up (the display shows “- - -”), then please check the following points:

1. The distance of the atomic clock or outdoor temperature sensor 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.
