GLOSSARY OF COMMON TERMS

NIST* The National Institute of Standards and Technology maintains the primary frequency standard for the United States. The NIST also coordinates the United States time and frequency standards with other world standards. The NIST provides time and frequency services for United States clientele.

WWVB

* The WWVB is an AM radio station in Ft. Collins, Colorado, managed by the NIST. The WWVB’s function is to broadcast time-of-day information derived from the NIST atomic clock, located in Boulder, Colorado.

ATOMIC CLOCK An atomic clock is an extremely accurate time device measuring time by the movements of electrons in cesium atoms. The NIST atomic clock is one of the most precise clocks in the world, accurate to 10 billionths of one second. The NIST’s atomic clock contributes to the international group of clocks calculating the Coordinated Universal Time (UTC)—the official world time.

RADIO-CONTROLLED TIME A radio-controlled time device is often confused with an atomic clock. However, a radio-controlled time device receives its time information from the atomic clock each day through an internal antenna. The radio-controlled time device searches for an exact time signal every night when the signal from the WWVB is the strongest. The signal can be received up to 2,000 miles away through a radio-controlled time device.

LCD “LCD” is an acronym for ”Liquid Crystal Display”. This is a common type of display screen used in televisions, computers, watches, and digital clocks.

CELSIUS (°C) Celsius is metric system’s unit of measurement used to calculate temperature.

FAHRENHEIT (°F) Fahrenheit is the common unit of measurement used to calculate temperature in the United States.

TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER (INSTALL BATTERIES IN TRANSMITTER BEFORE

INSTALLING BATTERIES IN RADIO-CONTROLLED CLOCK)

The transmitter uses 2 x AA, Alkaline batteries. To install and replace the batteries, please follow the steps below:

1. Remove the battery cover by pushing down towards bottom of transmitter and sliding cover out.

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

3. Replace the battery cover on the unit.

ALKALINE BATTERIES ARE RECOMMENDED FOR USE IN BOTH UNITS. AVOID USING RECHARGEABLE BATTERIES.

TO INSTALL AND REPLACE BATTERIES IN THE RADIO-CONTROLLED CLOCK

The radio-controlled clock uses 2 x AA, Alkaline batteries. To install and replace the batteries, please follow the steps below:

1. Remove the battery cover.

2. Insert batteries observing the correct polarity (see marking inside battery compartment).

3. Replace compartment cover.

DO NOT SET THE CLOCK. Note:

In the event of changing batteries of the unit, ensure that the batteries do not spring free from the contacts. Always wait at least 15 minutes after removing the batteries before reinserting, otherwise start up and transmission problems may occur.

REPLACEMENT OF BATTERIES

For best performance, batteries should be replaced at least once a year to maintain the best running accuracy. Ensure that the batteries used are new and the correct size.

Please help in the preservation of the environment and return used batteries to an authorized depot.

WARNING!

• Do not mix old and new batteries.

• Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel cadmium) batteries.

SETTING-UP:

NOTE: Do not set the clock until the outdoor temperature is displayed.

1. Place batteries in the outdoor transmitter first, then into the radio-controlled clock.

2. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

3. After 15 minutes both the Indoor and Outdoor areas on your clock should have a temperature showing. If not, remove both sets of batteries, wait 15 minutes and repeat step one.

4. After the clock receives the outdoor temperature, and 15 minutes have elapsed,

set your time zone. The default time zone is Eastern Standard Time (EST). If you live in the Eastern Time zone move to step 6.

5. To set the time zone:

• Push and release the “SET” function button.

• The time zone (LCD2) will start flashing (Default setting -5EST).

• Push the (+) function button to change the default setting (-5EST) to the desired

time zone.

-6 CST (Central Time Zone)

-7 MST (Mountain Time Zone)

-8 PST (Pacific Time Zone)

6. After the clock receives the outdoor temperature the WWVB time code reception will

(See “Time Zone Setting” if you live outside the USA)

automatically start. The clock will automatically set itself to the exact time, day and date after receipt of the WWVB time code reception. This typically takes over night. For best reception place your clock next to a window facing Colorado over night. Once a successful reception is received the Radio Reception ( ) icon will appear above the blinking colons. Once a successful reception is received relocate your clock to a desired location. The clock will then automatically attempt to receive the WWVB time from 12:00 am through 6:00 am each day (attempts WWVB reception every full hour within this time frame). When this is successful, the received time will override the

manually set time. The date is also updated with the received time (Please refer to

notes on “Manual time setting”).

ICON DESCRIPTION

Successful reception of WWVB time signal

Currently searching for the WWVB time signal (tower blinking)

Unsuccessful reception of WWVB signal. Will work as normal quartz clock. Will search for the WWVB time signal overnight.

FUNCTION KEYS

The radio-controlled clock has 4 easy to use keys: SET key : To enter into the set mode for the following functions: time zone, DST

ON/OFF (daylight saving time), language, hour, minute, year, month, day,

weekday, 12/24 hour, ºC or ºF temperature display + key : To toggle between the seconds, temperature or weekday display To change any values in manual set mode ALM key : To enter into the alarm set mode To set the alarm ON/OFF SNZ key : To activate the snooze function during alarm To display the alarm time in normal mode display To exit the setting modes

LCD SCREEN DESCRIPTIONS

The radio-controlled clock's LCD is divided into 2 sections. When batteries are inserted, all the segments will light up briefly before displaying the information for time, date, and indoor and outdoor temperatures.
