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 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.
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 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 10 minutes and repeat step one.
3.After the clock receives the outdoor temperature, set your time zone using the manual settings below. The default (factory) 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-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”).
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.

ATOMIC CLOCK LCD SCREEN DESCRIPTIONS
The atomic clock's LCD is divided into 2 sections and once the batteries are inserted, all the segments will light up briefly before displaying the information for time, date, indoor and outdoor temperatures.

WEATHER FORECAST
The weather forecasting feature is estimated to be 75% accurate. The weather forecast is based solely upon the change of air pressure over time. The WS-8157 averages past air-pressure readings to provide an accurate forecast, creating a necessity to disregard all weather forecasting for 12-24 hours after the unit has been set-up, reset, or moved from one altitude to another (i.e. from one floor of a building to another floor). In areas where the weather is not affected by the change of air pressure, this feature will be less accurate.
Weather Icons
There are 3 possible weather icons that will be displayed in the LCD 2:
Sunny—indicates that the weather is expected to improve (not that the weather will be sunny).
Sun with Clouds—indicates that the weather is expected to be fair (not that the weather will be sunny with clouds).
Clouds with Rain—indicates that the weather is expected to get worse (not that the weather will be rainy).
The weather icons change when the unit detects a change in air pressure. The icons change in order, from “sunny” to “partly sunny” to “cloudy” or the reverse. It will not change from “sunny” directly to “rainy”, although it is possible for the change to occur quickly. If the symbols do not change then the weather has not changed, or the change has been slow and gradual.
Weather Tendency Arrows
Other possible displays in LCD 2 are 2 weather tendency arrows, one that points up (on the left side of the forecast) and one that points down (on the right side of the forecast). These arrows reflect current changes in the air pressure. An arrow pointing up indicates that the air pressure is increasing and the weather is expected to improve or remain good. An arrow pointing down indicates that the air pressure is decreasing and the weather is expected to become worse or remain poor. No arrow means the pressure is stable.
MANUAL SETTINGS
Note:
If the atomic clock has already successfully received the WWVB time signal and displays the correct time and date, then the Manual settings can be skipped.
After completion of the above described procedures in “Setting up” the manual setting modes can be entered by pressing and holding the SET key for 3 seconds. The following settings can now be programmed:
•Time zone setting
•DST ON/OFF
•Language display setting
•Manual time setting
•Year setting
•Month setting
•Date setting
•Weekday setting
•12/24 hour time display setting
•ºC or ºF setting
TIME ZONE SETTING
After entering the manual setting mode as described above, the time zone can be set between the –1 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),
