Operating Environment
The ADC-A12C31 clock contains a stepper motor and microprocessor control electronics designed to
operate indoors between 32˚ to 140°F (0˚ to 60˚C) with 0-90% relative humidity, non-condensing.
The ADC-A12C31 is not water or moisture proof. Treat it as you would any other delicate
electronic device and do not expose it to water, excessive heat or physical abuse.
Operation
After applying power, the clock will go through an internal check. Time from the RTC backup will be
applied until a Time Code reference is acquired.
During this period the red status LED will be on solid and the hands will move in either a clockwise or
counter clockwise motion.
Status LED
The red LED on the ADC-A12C31 clock face, located at the 6:00 indicates;
LED STATE
STATUS INDICATION
Off
The clock acquired valid time code and has synchronized its internal
RTC to the time code reference. The internal clock time is considered
accurate. The clock hands may be adjusting/correcting rapidly either
clockwise or counter-clockwise during a correction.
On Solid
The clock is not able to decode the time code reference or the
reference is not present. Time displayed on the face of the clock is
based upon internal and TCXO and should not be considered
accurate.
Correction Behavior
The correction cycle engages when there’s a change to the internal RTC as compared to the time
code reference.
