OPERATION
This 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 Stan-
dards and Technology).
Upon installation of the batteries, the unit automatically
activates its receiver. It attempts to receive the signal every
four (4) hours and make any necessary changes to the
display.
You may not receive a signal immediately. It may take as
long as 72 hours to receive a complete signal from the Atomic
/ " LCD
8
Clock. While the unit is attempting to receive a complete
signal for the first time, the clock may be set manually (see
"Manual Clock Setting" section). Best signal reception often
occurs between midnight and 4 a.m.
Successful reception of the Atomic Clock signal is depen-
dent upon positioning and location of the unit. Insufficient
signal strength or external electrical interference may prevent
unit from receiving a complete signal. Main causes for poor
reception are heavily reinforced concrete and steel structures
and/or placement of unit close to video or PC monitors.
Certain areas of Eastern United States may experience urban
interference from United Kingdom's Atomic Clock that distort
or interfere with the signal from U.S. Atomic Clock.
INSTALLING BATTERIES
1. Lift the battery compartment door on back of unit.
2. Insert 2 AA Alkaline batteries using +/- signs inside
battery compartment for correct placement.

NOTE: After installing batteries, you may wish to manually
set all functions. Instructions follow for setting calendar, time
and temperature preferences.
SETTING CALENDAR
This unit constantly displays the current month, date and day
of the week.
To set the calendar:
1. On back of the unit, slide the LOCK/TIME SET/CALENDAR
switch to the CALENDAR position.
2. Press MONTH, DATE, and YEAR buttons until the correct
settings are displayed.
3. Slide the LOCK/TIME SET/CALENDAR switch to the LOCK
position.
NOTE: An incorrect calendar setting will automatically be
adjusted (i.e., April 31 will be adjusted to April 1 and with the
exception of a Leap Year - February 29 will be adjusted to
February 1).
NOTE: Year is not viewable in LOCK or TIME SET mode. To
view year, switch to CALENDAR position.
