be processed. Set the possible settings for the following menu item.
SETTINGS & DATAVIEW - If you select this item, you will open the
menus for settings of the receiver or the sensors connected. Select
the desired sensor or module through the selection keys . (See
the manual of the sensor or of the module)
SENSOR: List of the sensors connected and detected (only display,
no manual selection possible)
DISPLAY RF STATUS - Top row: Level of channels 1 … 75 coming
from the receiver of the 2.4 GHz band in dBm to the transmitter. Bot-
tom row: Level of channels 1 … 75 coming from the transmitter of
the 2.4 GHz band in dBm to the receiver.
SELECT ANNOUNCE - In the first line, assign a switch and set the
repetition time to start the voice output. In the next line "NEXT
ANNOUNCE" assign a switch to switch the announcements through.
In the "VARIO" line, assign a separate switch for the vario signals.
Select automatical (AUTO) or a specific sensor (GPS, EAM, GAM)for

Tap the SET button in the "TRANSMITTER, RECEIVER" line. In the list
that is now displayed, set which messages should be active for the
transmitter or receiver.

back channel (telemetry transmission). Use this function if the back
channel of the receiver is influenced by the back channel of another
receiver.
In the "ON" position the telemetry signals are processed continu-
ously. In the "1" position, the telemetry signals are processed with a
slight delay; the telemetry signals are processed in a very delayed
manner in position "10".
