Warning
When used outdoors, a lightning conductor must also be installed.
Note
One end of the shielding of the radio clock cable must be connected to a suitable
point at the place of installation.
Functional check
The "RADIO CLOCK" LED on the front panel must flash at about 1Hz when the
SICLOCK DCFRS is received correctly.
The parameter /Inputs/Input 1/Status (0.20.02) must change to "DCF77" after
about three minutes reception.
Note
If possible select a location for the aerial where there is no electromagnetic inter-
ference on the DCF77 carrier frequency, because this is crucial for the quality of
reception. Do not mount the aerial anywhere near electric drives, neon tubes,
monitors or other emitters of interference.
