For more details, consult the user manual of NTP version "NTP-option-
LEDI-LEDIWORLD-HANDI" and "GT NETWORK MANAGER" configuration's
tool available on the DVD CDG020 delivered with the clock.

2.1.6. DHW 869.525MHz Radio Version

the clock is automatically synchronized according to the transmitter setting (emitting
period). the clock is automatically updated after reception.
Extinction of the two second dots: 10 seconds without synchronization

2.1.7. Radiosynchronised version using a DCF antenna

Frequency received: 77.5 kHz
Position the DCF antenna so the LED flashes every sec and goes off at the 59th second.
Extinction of the two second dots: 600 seconds without synchronization
DCF sync source (transmitter in Germany) (UtC + 1h00 + summer or winter time)

2.1.8. Radiosynchronised version using a tDF antenna

tDF frequency received: 162 kHz
install the antenna in such a way that the screen printing and the indicator are on a
horizontal plane.
Extinction of the two second dots: 600 seconds without synchronization
tDF synchronization source (transmitter in France) (UtC + 1h00 + summer or winter time)
☛
After less than a minute, when reception conditions are correct, the
indicator will start flashing every second and go off at the 59th second. If
the indicator is still not flashing after 15 minutes, it is better to find another
