S-QUA (signal quality)
This value is a type of evaluation of usefulness, ex-
pressed as a percentage, 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 (reception level)
dBm is a logarithmic value that provides a comparative
overview of extreme differences in level. A level of 0 dBm
corresponds to 1 mW. The dBm is positive for an output
> 1 mW, and the dBm is correspondingly negative for an
output < 1 mW.
In practice, this means that when a remote control sys-
tem is used, generally (significantly) less than 1 mW and
hence a level < 0 dBm is received by the receiver from
a 100 mW output of a standard transmitter (= 20 dBm)
because of the fanning out of the radio waves and
associated weakening of the signal on the way to the
receiver. Consequently, 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.
Perform a range test before each flight as described
on page 77, and simulate all servo movements that
could occur during the flight. The range must be at least
50 m on the ground in an activated range test. At this
distance, a maximum of -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, you should not operate your model. Check the
installation of the receiver and antenna position.
During operation, the reception should not fall below
-90 dBm; 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.
S-STR (signal strength)
The signal strength (S-STR) is displayed in percentage.
In general, an acoustic range warning (1 beep every
second) is emitted once the receiver signal in the
feedback channel becomes too weak. Since the
transmitter's output is significantly higher than the
receiver, the model can always be operated safely. The
model distance should nevertheless be reduced for
reasons of safety until the warning tone stops.
R-TEM. (receiver temperature)
Make sure that the temperature of your receiver remains
within the permissible range under all flight conditions
(ideally between -10 and +55 °C).
The receiver temperature threshold which triggers a
warning can be set in the submenu "RX SERVO TEST"
under "ALARM TEMP+" (50 … 80°C) and "ALARM
TEMP-" (-20 … +10°C). When the temperature is too
high or too low, a continuous warning tone sounds, and
"TEMP.E" appears in red at the top right in the receiver
menu "RX". On the display page "RX DATAVIEW", the
parameter "R-TEM" is also displayed in red.
