TO DEACTIVATE THE ALARM:
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.
Alarm icon ((())) (ON)
Weather Tendency Arrows
The alarm will be automatically ON when the alarm time is set. To deactivate the alarm (OFF),
press and release once the ALM key in normal mode display. The alarm icon will disappear, the
alarm is now off.
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.
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:
WEATHER FORECAST
The temperature is measured and transmitted to the radio-controlled clock every 4 seconds.
The radio-controlled clock will update the temperature display every 20 seconds.
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.
The weather forecasting feature is estimated to be 75% accurate. The weather forecast is
based solely upon the change of air pressure over time. 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:
915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The radio-controlled clock will receive the temperature data within 4 seconds. If the temperature
data is not being received 2 minutes after setting up (or the display shows “- - -”), then please
check the following points:
1.
The distance of the radio-controlled 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.
Sunny—indicates that the weather is expected to improve (not that the weather will be sunny).
2.
3.
Avoid placing the receiver onto or in the immediate proximity of metal window frames.
Using other electrical products such as headphones or speakers operating on the same
signal frequency (915MHz) may prevent correct signal transmission and reception.
Neighbors using electrical devices operating on the 915MHz signal frequency can also
cause interference.
Sun with Clouds—indicates that the weather is expected to be fair (not that the weather will be
sunny with clouds).
4.
Clouds with Rain—indicates that the weather is expected to get worse (not that the weather
will be rainy).

Note: When the 915 MHz signal is received correctly, do not re-open the battery cover of either
the outdoor temperature transmitter or radio-controlled clock, as the batteries may spring free
from the contacts and force a false reset. Should this happen accidentally then reset all units
(see Setting-up above) otherwise transmission problems may occur.
FOLDOUT TABLE STAND
The foldout table stands legs are located on the backside. Unfold the stands out,
below the battery compartment. Once the foldout table stands are extended, place
the radio-controlled clock in an appropriate location.
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature
transmitter to the radio-controlled clock (in open space). However, this depends on the
surrounding environment and interference levels. If no reception is possible despite the
observation of these factors, all system units have to be reset (see Setting-up).
WALL MOUNTING
1)Using a straightedge, horizontally space at 3.93“ (100 mm) three screw
positions on a wall.
Note: In case the radio-controlled clock is not able to detect the WWVB-signal (disturbances,
transmitting distance, etc.), the time can be manually set (please refer to notes on Manual time
setting).
2)
Install three mounting screws (not included) into a wall within transmission
range—leaving approximately 3/16 of an inch (5mm) extended from the wall.
Place the radio-controlled clock onto the screws, using the hanging holes on
the backside. Gently pull the radio-controlled clock down to lock the screws
into place.
3)
POSITIONING
Before permanently mounting, ensure that the radio-controlled clock is able to receive WWVB
signals from the desired location. Also, extreme and sudden changes in temperature will
decrease the accuracy of the radio-controlled clock, and changes in elevation will result with
inaccurate temperatures readings for the next 12 to 24 hours. These changes will require a 12
to 24 hour wait before obtaining reliable data.
Note: Always ensure that the radio-controlled clock locks onto the screws before releasing.
POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER
The outdoor temperature transmitter can be mounted with the use of screws:
MOUNTING WITH SCREWS
To achieve a true temperature reading, avoid mounting where direct sunlight can reach the
outdoor temperature transmitter. It is recommended to mount the outdoor temperature
transmitter on a North-facing wall or in any well shaded area. The maximum transmitting range
is 330 feet (100 meters) obstacles such as walls, concrete, and large metal objects can reduce
the range.
1)
2)
Remove the mounting bracket from the outdoor temperature transmitter.
Place the mounting bracket over the desired location. Through the two screw
holes of the bracket, mark the mounting surface with a pencil.
Where marked, start the screw holes into mounting surface.
Screw mounting bracket onto the mounting surface. Ensure that the screws are
flush with the bracket.
3)
4)
Place both units in their desired location, and wait approximately 10 minutes before
permanently mounting to ensure that there is proper reception. The outdoor temperature
transmitter is not waterproof and should not be placed anywhere it will become submerged in
water or be directly in the rain.
