La Crosse Technology WS-9057U Battery Change, Device Reset, About Wwvb Radio Controlled Time

∙When the weather station is receiving the WWVB time signal, the outdoor transmitter data signal will temporarily not be received by the weather station. During this short period of time, the outdoor readings shown on the weather station will not be renewed until the WWVB time signal is successfully received.

TO INSTALL AND REPLACE BATTERIES IN THE THERMO- HYGRO TRANSMITTER

The Thermo-Hygro Transmitter uses 2 x AA, IEC, LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Remove the cover.

2. Insert the batteries, observing the correct polarity (see marking).

3. Replace the battery cover.

Note:

In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is due to a random security code assigned by the transmitter at start-up. This code must be

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.

Please participate in the preservation of the environment. Return used batteries to an authorized depot.

DEVICE RESET

The Weather Station and the Thermo-hygro transmitter need to be reset when one of the following conditions occur:

∙Unsuccessful 915 MHz signal reception.

∙Malfunction on the units.

∙Batteries replacement.

For resetting, remove all batteries from the units. Wait at least for 1 minute before powering up the Weather station again. Proceed from step 1 in “Setting Up”.

received and stored by the Weather Station in the first 3 minutes of power being supplied to the transmitter.

TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION

The Weather Station uses 2 x C, IEC LR14, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1.Insert finger or other solid object in the space at the bottom center of the battery compartment and lift up to remove the cover.

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 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 (303)499-7111. 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
