tion is very limited during daylight hours. The Wireless Weather Sta-
tion will search for a signal every night when reception is best. The
WWVB radio station derives its signal from the NIST Atomic clock in
Boulder, Colorado. A team of atomic physicists continually measure
every second of every day to an accuracy of ten billionths of a second
a day. These physicists have created an international standard, mea-
suring a second as 9,192,631,770 vibrations of a Cesium 133 atom in
a vacuum. For more information about WWVB please see the NIST
website at http://www.boulder.nist.gov/timefreq/stations/wwvb.htm
QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable
batteries.
1. Have the Wireless Weather Station and remote temperature sen-
sor 3 to 5 feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then
Wireless Weather Station.
(All remote temperature sensors must be started before the
Wireless Weather Station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and remote temperature sen-
sor will start to talk to each other and the display will show both the
indoor temperature and humidity, and an outdoor temperature. If the
Wireless Weather Station does not display both temperatures after
the 15 minutes please retry the set up as stated above. After both
indoor and outdoor temperatures are displayed for 15 minutes you can
place your remote temperature sensor outdoor and set your time.
The remote temperature sensor should be placed in a dry, shaded
area. The temperature sensor has a range of 330 feet. Keep in mind
that the 330 feet is in open air with no obstructions and that radio
waves DO NOT curve around objects. Actual transmission range will
vary depending on what is in the path of the signal. Each obstruction
(roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal
range in half.
Example: A Wireless Weather Station with a 330 feet range is mounted
on an interior wall, so that the signal has to pass through one interior
wall, one exterior wall, and across the 10 feet width of the room be-
tween the 2 walls. The first wall will reduce the range to 165 feet, and
the second wall will reduce the range to 87 feet. Factoring in the 10
foot room, this leaves a maximum of 77 feet of remaining signal range.

This allowance is typically enough for a frame wall with non-metallic
siding; however certain materials can reduce range even further. Metal
siding, stucco, and some types of glass can reduce signal range by as
much as 3/4 or more, compared to the 1/2 reduction typical of most
obstructions. It is possible to receive a signal through these materials,
however maximum range will be much less due to their tendency to
absorb or reflect a much larger portion of the sensor's signal.
DETAILED SET-UP GUIDE
I. BATTERY INSTALLATION (When one temperature sensor is
being used)
1. First, insert the batteries to the temperature sensor (see "A. Re-
mote Temperature Sensor" below).
2. Within 2 minutes of powering up the sensor, insert the batteries to
the Weather Station (see "B. Wireless Weather Station" below).
Once the batteries are in place, all segments of the LCD will light
up briefly. Following the indoor temperature and humidity, and the
time as 12:00 will be displayed. If they are not shown in LCD after
60 seconds, remove the batteries and wait for at least 60 seconds
before reinserting them. Once the indoor data is displayed user
may proceed to the next step.
3. After the batteries are inserted, the Weather Station will start re-
ceiving data signal from the sensor. The outdoor temperature should
then be displayed on the Weather Station. If this does not happen
after 2 minutes, the batteries will need to be removed from both
units and reset from step 1 and the signal reception icon is no longer
shown.

Battery Compartment
1. Remove the mounting bracket. The bracket snaps on and off easily.
2. Remove the battery cover, by sliding the cover down.
