To stop the servo test, re-activate the input fi eld as de-
scribed previously, then select STOP and confi rm your
choice with the INC+DEC button.
ALARM VOLT (low receiver voltage warning)
ALARM VOLT monitors the receiver voltage. The
threshold can be set to any value within the range 3.0
to 6.0 Volt. If the voltage falls below the set alarm limit,
an audible signal (interval beeping, long / short) is
triggered, and "VOLT.E" fl ashes at top right in all "RX ..."

ALARM TEMP +/- (receiver temperature monitor)
These two options monitor the temperature of the
receiver: a lower limit value "ALARM TEMP-" (-20 ...
+10°C) and an upper limit value "ALARM TEMP+" (50 ...
80°C) can be programmed. If the temperature exceeds
the upper limit or falls below the lower one, an audible
signal (continuous beeping) is triggered, and "TEMP.E"
appears at top right in all receiver displays. The parame-
ter "R-TEM" is also highlighted in the "RX DATAVIEW"
display.
Ensure that the receiver remains within the permitted
temperature range under all fl ight conditions (ideally
between -10 and +50°C).
CH OUTPUT TYPE
At this point you can select how the receiver outputs are
to be addressed.
• ONCE
The receiver servo sockets are addressed in se-
quence; this is recommended for use with analogue
servos. At this setting the servos are automatically
operated at a frame rate of 20 ms (30 ms with the
twelve-channel receiver, Order No. 33512) - regard-
less of what is set or displayed in the "PERIOD" line
of the "RX SERVO" display.
• SAME
The receiver servo sockets are addressed in parallel
blocks of four, i. e. if you are using the GR-12 recei-
ver included in the set, channels 1 to 4 and channels
5 and 6 each receive their control signals simultane-
ously.
This is recommended for use with digital servos, and
00°C
especially where multiple servos are employed for
00°C
a single function (e. g. ailerons), to ensure that the
groups of servos run absolutely synchronously.
If you are using digital servos, we recommend that
you set 10 ms in the "PERIOD" line of the "RX SER-
VO" display so that you can exploit the fast response
of these servos. If you are using analogue servos, it
is essential to select "20 ms".
If you choose the faster setting, please take par-
ticular care when selecting the receiver power
supply: since up to four servos can start moving si-
multaneously, the load on the battery is fairly severe,
so it must be a high-performance type.
• SUMO (Sum signal OUT)
A HoTT receiver confi gured as SUMO constantly ge-
nerates what is known as a sum signal from the con-
trol signals of all its control channels. This signal is
present, for example, at servo socket 6 of the GR-12
receiver.
The maximum sum signal can be set independent
from the receiver up to 16 channels, e.g. a 6-channel
receiver can be programmed on SUMO 12 and trans-
mits all 12 channels on the output.
After SUMO is selected and saved with INC+DEC,
the inverse marker jumps forward to the channel
number, here 06:
Pressing INC or DEC selects the number of chan-
nels to be transmitted in the sum signal.
saves the settings.
The receiver outputs are addressed in sequence at a
frame rate of 20 ms (30 ms with the GR-24 receiver,
Order No. 33512), even if you have set 10 ms in the
"PERIOD" line of the "RX SERVO" screen page.

two HoTT receivers, as described below, the sum si-
