Operating Environment
The CLKTCD clock contains a stepper motor and microprocessor control electronics designed to
operate indoors between 0‐50°C with 0‐90% relative humidity.
The CLKTCD 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 CLKTCD will go through an internal checkout. UTC (Universal Coordinated
Time) from the RTC (Real Time Clock) backup will then be displayed plus any Time Zone and/or DST
(Daylight Saving Time) offsets, until a time code signal is acquired. If time code is not “locked”, the
red status LED will be on solid until time code is acquired.
Status LED
The red LED on the CLKTCD 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 reference as compared to the
time code reference.
