Parallel Orientation; Vertical Orientation - Siemens SICLOCK DCFRS Betriebsanleitung

2.3.2.1 Parallel orientation

With parallel erection the erection is done on a cubicle or suspended from the ceiling. After connection
to the PC the LED must flash or light up. To establish optimum orientation the antenna should be
rotated in parallel to the earth's surface until the LED ceases to flash or flashes irregularly (on or off).
At that position the antenna is at reception minimum. To achieve reception maximum the antenna
0
must be rotated 90 to the left or to the right.

2.3.2.2 Vertical orientation

With vertical orientation erection is done on a wall. For this the antenna underside should be parallel to
the floor. If the LED does not flash regularly every second, a different antenna location should be
chosen which is a 90° angle to the current location.

The antenna should not be fixed in place until there is interference-free reception.
