S-QUA
This value is a type of evaluation of usefulness, expressed as a per-
centage, of the signal packages from the transmitter arriving at the
receiver.
This evaluation in percentage of the quality of the signal packages
from the transmitter received by the receiver's microprocessor is
shown live on the transmitter's display via the receiver's feedback
channel.
S-dBm
dBm is a logarithmic value that provides a comparative overview of
extreme differences in level. A level of 0 d Bm corresponds to 1 m W.
The dBm is positive for an output > 1 m W, and the dBm is corre-
spondingly negative for an output < 1 m W.
In practice, this means that when a remote control system is used,
generally (significantly) less than 1 mW and hence a level < 0 d Bm is
received by the receiver from a 100 mW output of a standard trans-
mitter (= 20 d Bm) because of the fanning out of the radio waves and
associated weakening of the signal on the way to the receiver. Con-
sequently, the reception shown in dBm in the display is generally
negative. The higher the number after the minus sign, the worse the
reception. This is important to remember during range tests before
using the model.
The range must be at least 50 m in an activated range test. At this
distance, a value not worse than -80 dBm may be displayed in the "RX
DATAVIEW" display under "S-dBm" to ensure safe operation. If the
value is lower, such as -85 dBm, the model should not be put into
operation, but the installation of the receiving system and the posi-
tion of the antennas should be checked.
During operation, the reception should not fall below -90 d Bm; if this
is the case, you should reduce your distance to the model. Normally
before this level is reached, the acoustic range warning is triggered
(one beep every second) which reflects the signal strength of the
feedback channel to ensure safe operation.
