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.
The atomic clock has four easy to use keys:
SET key : To enter into the set mode for the following functions: time zone, DST ON/OFF
(daylight saving time), language, hour, minute, year, month, day, weekday, 12/24
hour, ºC or ºF temperature display
+ key : To toggle between the second, temperature or weekday display
To change any values in manual set mode
ALM key : To enter into the alarm set mode
To set the alarm ON/OFF
SNZ key : To activate the snooze function during alarm
To display the alarm time in normal mode display
To exit the setting modes
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.
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.
