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 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: 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 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.

Note:
Weather Icons
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.
There are 3 possible weather icons that will be displayed in the LCD 2:
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:
Sunny—indicates that the weather is expected to improve (not that the weather will be sunny).

Time zone setting

DST ON/OFF
Language display setting
Manual time setting
Year setting
Month setting
Sun with Clouds—indicates that the weather is expected to be fair (not that the weather will be sunny
with clouds).
Date setting
Weekday setting
Clouds with Rain—indicates that the weather is expected to get worse (not that the weather will be
rainy).
12/24 hour time display setting
ºC or ºF setting
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.
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:
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.
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),
