Low voltage warning (ALARM VOLT): if the receiver voltage falls below the selected voltage, the
transmitter’s RF module generates a low voltage warning in the form of a “general alarm sound”: a stea-
dy beeping at intervals of about one second or the voice announcement „receiver voltage“.
Temperature warning (ALARM TEMP): if the receiver temperature falls below the selected temperature,
the transmitter’s RF module generates a temperature warning in the form of a “general alarm sound”: a
steady beeping at intervals of about one second or the voice announcement „receiver temperature“.
Cycle time (PERIOD): with the use of only digital servos, a cycle time of 10 ms can be set. In mixed operation
or with use of only analog servos, 20 ms should absolutely be set, because the latter can otherwise be „over-
strained“ and react with „shaking“ or „quivering“ as a result.
HoTT Sum signal (SUMH):
if the digital HoTT sum signal at channel 6 is activated, the sum signal with up to
eight channels is generated at this socket instead of a servo signal. This is important for optional devices which
require this signal.
Voltage measurement (VOLTAGE at CH5): if voltage measurement at channel 5 is activated, a voltage up to
max. 25.5 V DC can be monitored via this input using the circuit described below, instead of a servo. The volta-
ge is then displayed on the screen instead of the receiver voltage. This provides a direct means of monitoring
the fl ight battery without the need for an additional sensor.
Note: Additional sensors can not be connected to the receiver at the moment!

that this is the case.
Individual markings indicate which materials can be recycled and re-used. You can make an
important contribution to the protection of our common environment by re-using the product, recycling
the basic materials or recycling redundant equipment in other ways.
Remove batteries from your device and dispose of them at your local collection point for batteries.
In case of R/C models, you have to remove electronic parts like servos, receiver, or speed controller
from the product in question, and these parts must be disposed of with a corresponding collection point
for electrical scrap.
If you don’t know the location of your nearest disposal centre, please enquire at your local council of-
fi ce.
