Control Company 1077 ATOMIC WALL CLOCK - Manual

Traceable ® is a registered trademark of Control Company ©2007 Control Company. 92-1077-00 Rev. 3 121807
SPECIFICATIONS
Receiver: Integrated radio receiver for reception of the
time signal
Internal Timing: Quartz Crystal
Accuracy: 1/10,000 of a second when receiving signal
Signal Reception: Seven (7) times per day
OPERATION
The clock 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).
Prior to installing the battery, slide the time zone switch to the desired time
zone:
P = Pacific Standard Time
M = Mountain Standard Time
C = Central Standard Time
E = Eastern Standard Time
Once the desired time zone has been selected, install the battery. Upon
installation of the battery, the clock will activate its receiver and initiate signal
reception (See the “Signal Reception” section).
SIGNAL RECEPTION
Upon installation of the battery, or upon pressing the REC button, the clock will
initiate signal reception:
The seconds hand will advance rapidly and stop near the 12 o’clock
position.
The minutes hand advance rapidly and stop near the 12 o’clock position
once the hours hand reaches the 12, 4, or 8 o’clock position (whichever is
closest).
The clock will attempt to receive the Atomic Clock signal every hour over
the next 24 hours. While attempting to receive the signal during the first 24
hours, the clock hands will not move until a complete signal has been
received.
The clock may not receive a signal immediately. It may take as long as 24
hours to receive a complete signal from the Atomic Clock. Best reception
often occurs between midnight and 4 a.m.
Upon successful reception of the signal from the Atomic Clock, the clock will
display the correct time and will attempt to receive the signal seven times per
day and make any necessary adjustments.
If the clock is unable to receive a complete signal within the first 24 hours,
the clock hands will start moving; however, the incorrect time will be
displayed. After 24 hours, if the clock hands are moving and displaying the
incorrect time, the clock should be moved to a different location that provides
for better signal reception (See the “Manually Initiating Signal Reception”
section).
The successful reception of the Atomic Clock signal is dependent upon the
positioning and location of the clock. Insufficient signal strength or external
electrical interference may prevent the clock from receiving a complete
signal. The main causes for poor reception are heavily reinforced concrete
and steel structures, structures with few or no windows, and/or placement of
the clock 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.
MANUALLY INITIATING SIGNAL RECEPTION
When the clock is moved to a new location, it is recommended that you
manually initial signal reception to insure that the clock will receive a
complete signal in the new location.
To manually initiate signal reception, press and hold the REC button until the
seconds hand begins to advance rapidly (See the “Signal Reception”
section). Pressing the REC button while the clock is already in signal reception
mode will have no affect.
DAYLIGHT SAVING TIME
The DST switch should remain in the ON position unless the clock is being
utilized in a location that does not observe Daylight Savings Time. For
locations that do not observe Daylight Savings Time, slide the DST switch
to the OFF position.
MANUAL CLOCK SETTING
Setting the clock manually is only recommended if the clock is being utilized
in a location that is unable to receive a signal from the Atomic Clock.
To set the clock manually, press and hold the M.SET button until the correct
time appears on the clock.
ALL OPERATIONAL DIFFICULTIES
If this clock does not function properly for any reason, replace the battery
with a new high quality battery (see “Battery Replacement” section). Low
battery power can occasionally cause any number of “apparent”
operational difficulties. Replacing the battery with a new fresh battery will
solve most difficulties.
BATTERY REPLACEMENT
Open the battery cover door. Remove the exhausted battery and
replace with a new AA alkaline battery. Close the battery cover door.
Upon installation of the battery, the clock automatically initiates signal
reception (See the “Signal Reception” section.)
