ALARM VOLT (low receiver voltage warning)
ALARM VOLT monitors the receiver voltage. The thresh-
old 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 trig-
gered, and “

” fl ashes at top right in all “RX …” 

screen displays:

The parameter “R-VOLT“ is also highlighted in the “RX 
DATAVIEW” display:

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 “

” 

appears at top right in all receiver displays. The param-
eter “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.

The receiver servo sockets are addressed in se-
quence; this is recommended for use with analogue 
servos. At this setting the servos are automatical-
ly 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 receiv-
er 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 
especially where multiple servos are employed for 
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.

A HoTT receiver confi gured as SUMO constant-
ly generates what is known as a sum signal from the 
control signals of all its control channels. This signal 
is present, for example, at servo socket 8 of the GR-
16 and GR-24 receiver.
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.
Although primarily intended for “satellite mode” with 
two HoTT receivers, as described below, the sum 
signal generated by the receiver defi ned as SUMO 
can also be used, for example, to control a fl ybar-
less system, or to control a fl ight simulator (using the 
adapter lead, Order No. 33310).
In …
Satellite mode
… two HoTT receivers are inter-connected using a 
three-core connecting lead (Order No. 33700.1 (300 
mm) or 33700.2 (100 mm) by the highest-numbered 
servo sockets. For more details on this please visit 
www.graupner.de on the Internet.
All channels of the HoTT receiver which is confi gured 
as SUMO, and is defi ned as the satellite receiver, are 
constantly transferred to the second HoTT receiver - 
the primary receiver - via this connection . The prima-
ry receiver must be programmed as the …
SUMI (Sum signal IN). 

Note that the signal only ever moves in one direction: 
towards the SUMI.
However, if reception fails, the receiver defi ned as 
SUMI only uses the sum signal coming from the
