TO INSTALL AND REPLACE BATTERIES IN THE WIRELESS
TEMPERATURE SENSOR
The wireless temperature sensor uses 2 “AA” Alkaline Batteries. To
install and replace the batteries, please follow the steps below:
1. Remove the battery cover.
2. Insert the batteries, observing the correct polarity (see
marking).
3. Replace the battery cover on the unit.

Note: In the event of changing batteries in any of the units, all units need to be reset by
following the set-up procedures. This is due to a random security code assigned by the
wireless temperature sensor at start-up. This code must be received and stored by the
wireless weather station in the first 3 minutes of power being supplied to the wireless
temperature sensor.
TO INSTALL AND REPLACE BATTERIES IN THE WIRELESS WEATHER
STATION
The wireless weather station uses 2 “AA” Alkaline Batteries. To install and replace the
batteries, please follow the steps below:
1. Push down on the top center of the
battery cover and pull away from the
unit to remove the cover.
2. Insert batteries observing the correct
polarity (see marking).
3. Replace compartment cover.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure
optimum accuracy of these units.

47
Please participate in the preservation of the environment. Return
used batteries to an authorized depot.
SETTING UP
1. First, insert the batteries into the wireless temperature sensor (see “To install and
replace batteries in the wireless temperature sensor”)
2. Within 4 minutes of activating the wireless temperature sensor, insert the batteries
into the wireless weather station (see “To install and replace batteries in the
wireless weather station”). Once the batteries are in place, all segments of the
LCD will light up briefly and a short signal tone will sound. If the indoor
temperature and indoor humidity are not displayed after 15 seconds, remove the
batteries and wait for at least 3 minutes before reinserting them. Once the indoor
data is displayed proceed to step 3.
3. After inserting the batteries into the wireless temperature sensor, the wireless
weather station will start receiving data from the temperature sensor. The outdoor
temperature should then be displayed on the wireless weather station. If this does
not happen after 3 minutes, the batteries will need to be removed from both units
and reset from step 1.
4. The wireless weather station can receive up to 3 temperature sensors. If you have
purchased additional temperature sensors, repeat from step 1 for all extra
temperature sensors. However, ensure that you leave 10 seconds in between the
reception of the last temperature sensor and the set-up of the following
temperature sensor. The wireless weather station will number the temperature

48
sensors in the order of set-up, i.e. the first temperature sensor will have the
temperature displayed with the number 1 against it and so on.
5. With less than 3 temperature sensors received, the wireless weather station will try
to pick up the remaining one in approximately another 3 minutes. If 3 temperature
sensors are received, the wireless weather station will stop further reception.
6. Once the outdoor temperature has been received and displayed on the wireless
weather station, the WWVB time code reception is automatically started. This
takes typically between 6-8 minutes in good conditions.
7. If after 10 minutes, the WWVB time has not been received, use the SET key to
manually enter a time initially. The clock will automatically attempt to receive the
WWVB time from 12:00 to 6:00 a.m. for a successful reception. When WWVB
reception signal is successful, the received time will override the manually set
time. The date is also updated with the received time. The next reception attempt
will occur on the following day. (Please refer to notes on “About WWVB Radio
controlled Time” and “Manual Time Setting”).
Your wireless weather station is now operational!
RESETTING WIRELESS WEATHER STATION
The wireless weather station and the wireless temperature sensor need to be reset when
one of the following conditions occur:
•Unsuccessful 433MHz signal reception of the wireless temperature sensor.
•Malfunction of the units.
•Batteries need replacement.

49
In order to establish proper communication between the display and outdoor sensor it is
important that they be set up as follows:
1. Bring any units outside, inside and place all units 3-5 feet apart with nothing in-
between them.
2. Remove batteries from all units.
3. Press any of the buttons on the display at least 10 times to clear the memory.
Verify that the display is blank before proceeding.
4. Using good quality alkaline batteries, place the batteries back into the wireless
temperature sensor(s); making sure that they are installed according to the
diagrams in the battery compartment.
5. Taking care not to press any buttons, re-install the batteries in the weather station
according to the diagram in the battery compartment.
6. Do not press any buttons for at least 15 minutes after installing the batteries.
(This is to let them establish a good connection.)
ABOUT WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology—Time and Frequency
Division) WWVB radio station 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 weather projection
station. However, due to the nature of the Earth’s Ionosphere, reception is very limited

50
during daylight hours. The wireless weather station will search for a signal every night
when reception is best.
The WWVB radio station receives the time data from the NIST Atomic clock in Boulder,
Colorado. A team of atomic physicists is continually measuring every second, of every
day, to an accuracy of ten billionths of a second per day. These physicists have created
an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-
133 atom in a vacuum. For more detail, visit http://www.boulder.nist.gov/timefreq.htm. To
listen to the NIST time, call [phone]. This number will connect you to an
automated time, announced at the top of the minute in “Coordinated Universal Time”,
which is also known as Greenwich Mean Time (GMT). This time does not follow Daylight
Saving Time changes. After the top of the minute, a tone will sound for every second. It is
possible that your wireless weather station may not be exactly on the second due to the
variance in the quartz. However, the clock will adjust the quartz timing over the course of
several days to be very accurate; under 0.10 seconds per day.

Note:
The unit will still try to receive the signal between 12:00 to 6:00 a.m. every day even if the
time has been manually set and if the WWVB time reception function has been set ON.
When it does receive the signal, it will change the manually set time into the received
time. During reception attempts the WWVB tower icon will flash. If reception has been
unsuccessful, then the WWVB tower icon will not appear but reception will still be
attempted the following hour.
CALENDAR SETTING
The date default of the wireless weather station is 1. 1. in the year 2005. Once the radio-
controlled time signals are received, the date is automatically updated. However, if the
signals are not received, the date can also be set manually:
1. The year starts flashing.
