TCXO AND RTC CIRCUIT
The Display contains a RTC (Real Time Clock) circuit allowing
the display to maintain an accuracy of ± 1 minute per year
to the last known Time Code input (± 165 mSec per day)
when Time Code is not present or cannot be decoded (i.e.
freewheeling mode).
MAINTENANCE-FREE RECHARGEABLE BATTERY
The RTC is maintained continuously from a rechargeable
battery circuit during periods of power outage. Minimum
holdover period is two weeks with a fully-charged battery
under constant drain.
DEFAULT CONFIGURATION
The factory defaults may be restored by using the
WinDiscovery program, or by using the reset button at the
rear of the TCDS-A.
Your TCDS-A display ships from the factory with the
following configuration as defined below. The TCDS-A
firmware interprets incoming time signals as UTC.
