OPERATION
The unit contains a pre-tuned internal radio receiver that receives a 60 kHz frequency
signal generated by the U.S. Atomic Clock. The U.S. Atomic Clock is located in
Boulder Colorado and is operated by NIST (National Institute of Standards and
Technology).
Upon installation of the battery, the time zone will flash on the display. Press the
ZONE button to select the desired time zone:
PST = Pacific Standard Time
MST = Mountain Standard Time
CST = Central Standard Time
EST = Eastern Standard Time
Once a time zone has been selected, the unit automatically activates its receiver.
Upon successful reception of the signal from the Atomic Clock, it then attempts to
receive the signal every four (4) hours and make any necessary changes to the
display.
The unit may not receive a signal immediately. It may take as long as 72 hours to
receive a complete signal from the Atomic Clock. While the unit is attempting to
receive a complete signal for the first time, the clock may be set manually (see the
"Manual Clock Setting" section). Best reception often occurs between midnight and 4
a.m.
The successful reception of the Atomic Clock signal is dependent upon the positioning
and location of the unit. Insufficient signal strength or external electrical interference
may prevent the unit from receiving a complete signal. The main causes for poor
reception are heavily reinforced concrete and steel structures and/or placement of the
unit close to video or PC monitors. There are certain areas of the Eastern United
States where urban interference or signals from the United Kingdom's Atomic Clock
may distort or interfere with the signal from the U.S. Atomic Clock.
SELECTING TEMPERATURE UNIT OF MEASURE
While the time-of-day is on the display, each press of the SET button toggles the
temperature display from °F and °C.

if Daylight Saving Time is on, "DST" will appear to the left of the Signal Strength
Indicator.
