6.1 THE CONTROL LEDS
The NeoClock receiver is equipped with two control LEDs that indicate the
status of the receiver at any time. The operation of these LEDs depends
on the system of antennas (DCF77 or France Inter) used by the NeoClock
receiver.
6.1.1 DCF77 antenna system
POWER LED
(or left LED in front view on the desk version)
red blinking:
Indicates that the NeoClock receiver has not yet been able to decode the
time data coming from the atomic clock since it has been powered. Also
indicates that the time data coming from the atomic clock could not be
decoded without error by the NeoClock receiver for the past 24 hours.
green blinking:
Indicates that the time data coming from the atomic clock could be
decoded without error. These data were sent to the connected PC through
the V24/RS232 connection and were also used to synchronise the
autonomous quartz clock of NeoClock.
RADIO SIGNAL LED
(or right LED in front view on the desk version)
off:
Indicates that the signal DCF77 is not received correctly.
green:
Indicate that the DCF77 signal is received correctly during more than 2
seconds. This LED must be lit without interruption so that the radio signal
can be decoded without error.
This LED switches on as soon as the signal is picked up. It switches out
during 2 seconds each time the reception is interrupted. If this happens,
move the receiver until the LED switches on again.
