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 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,1.5V batteries. To install and replace the batteries, please follow
the steps below:
1.
2.
3.
Remove the battery cover by pushing down towards bottom of transmitter and sliding
cover out.
Insert the batteries, observing the correct polarity (see marking inside battery
compartment).
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,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.
2.
3.
Insert batteries observing the correct polarity (see marking inside battery compartment).
Replace compartment cover.
DO NOT SET THE CLOCK.
BATTERIES CHANGE:
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.
