Quick setup manual
SET UP:
INSTALL BATTERIES IN THE TRANSMITTER:
Remove the screws and the battery cover from the back of the
W186-E transmitter with a small screwdriver.
Select the channel to transmit the outdoor temperature to the display.
NOTE: if using more than one transmitter, set each to a different
channel to be displayed on the clock.
Insert two fresh AAA alkaline batteries into the transmitter,
observing the correct polarity (see markings in battery compartment).
Select Fahrenheit or Celsius for the sensor display.
Press TX button to send a signal to the clock.
Keep transmitter 5-10 feet from the clock
The transmitter display should be showing a temperature reading.
If not please check battery polarity or try a new set of batteries.
INSTALL BATTERIES IN THE CLOCK:
Remove the battery cover from the clock:
Insert a finger in the rounded depression at the bottom of
the battery cover.
Lift up and pull out to remove battery cover.
Install three fresh AA alkaline batteries according to the polarity
markings.
Replace battery cover.
Once the batteries are in place, all segments of the LCD will light up
briefly. Then the indoor temperature will be displayed. If the indoor
temperature is not shown in the LCD after 60 seconds, remove the
batteries and wait for at least 60 seconds before reinserting them.
Within three minutes the outdoor temperature should be displayed on
the clock. If the outdoor temperature is not displayed within three
minutes, remove the batteries from both units and start again.
In order to ensure sufficient 434 MHz transmission, the outdoor
transmitter should be placed a distance of no more than 100 feet (30
meters, open air) from the Atomic clock.
WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, Colorado and
transmits the exact time signal continuously throughout the United States at
60 kHz. The signal can be received up to 2,000 miles away through the
internal antenna in the atomic clock. However, due to the nature of the
Earth’s Ionosphere, reception is very limited during daylight hours. The
atomic clock will search for a signal every night when reception is best.
If the tower icon flashes, but does not set the time or the WWVB tower does
not appear at all, then check the following:
Recommended distance from any interfering sources like computer
monitors or TV sets is a minimum of 6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures), the
received signal is weakened. In extreme cases, please place
the unit close to a window and/ or point its front or back towards the
Fort Collins, Colorado, transmitter.
During nighttime, the atmospheric disturbances are usually less severe
and reception is possible in most cases. A single daily reception is
adequate to keep the accuracy deviation below 1 second.
WWVB RECEPTION icon with full signal strength will appear on
screen if the reception of atomic time is successful. The atomic clock will
have a daily synchronization at 02:03 and 03:03 everyday. Each reception
cycle is minimum 2.5 minutes and maximum 10 minutes.

WEATHER FORECAST ICONS:
The unit predicts weather condition of the next 12 – 24 hours based on the
change of atmospheric pressure. The weather forecast is about 70-75%
correct. As weather conditions cannot be 100% correctly forecasted, we
cannot be responsible for any loss caused by an incorrect forecast.
