Installation Notes
generally do not survive such a high number of charge
/ discharge cycles as is claimed for other batteries,
such as Nanophosphate® types. The comparatively
high nominal voltage of 7.4 Volt of a two-cell LiPo pack
presents no problems to Graupner HoTT receivers, nor
to those servos, speed controllers, gyros, etc. which are
expressly approved for use at these higher voltages.
Please note, however, that virtually all servos, speed
controllers, gyros etc. sold in the past, and also
most of those currently available, are only approved
for use on an operating voltage in the range 4.8 to 6
Volt. If you wish to connect these devices to the recei-
ver, it is essential to use a stabilised regulated power
supply, such as the PRX, Order No. 4136; see Appendix.
If you neglect this, there is a danger that the connected
devices will quickly suffer permanent damage.

Program description: servo settings
Servo travel „Dual Rate“
To adjust servo travel symmetrically, i. e. to adjust travel
equally on both sides of neutral for elevator, rudder and
aileron. The adjustment range is fi xed and can be selec-
ted between 70% (switch in lower position) and 100%
(switch in upper position) of servo travel.
Note:
With the optional Smart-Box the servo travel can be
programmed separately and also asymmetrically for all
channels. See the section „telemetry“ on page 113.
The mx-10 HoTT can adjust the servo direction and
servo travel - dual rate.
Servo rotating direction
The direction of servo rotation can be adjusted to suit
the actual installation in your model. This means that
you don’t need to concern yourself with servo directions
when installing the mechanical linkages in the model,
as you can reverse them as and when necessary. The
rotationg direction is be set individually for each channel
with the servo reverse - switches on the front of the
transmitter. The direction is symbolized by „NOR“ for
normal rotation and „REV“ to reverse the direction of
rotation.

Fail Safe
In its default state (as delivered) the receiver is set to
Hold” mode, i.e. if a fail-safe situation occurs, all the ser-
vos connected to it maintain the last position detected
as valid. In this mode the green LED on the receiver
expires when interference occurs, and the orange LED
on the transmitter starts fl ashing 3-times for a short pe-
riod. In addition the transmitter also starts beeping in the
same way like the Status-LED as an audible warning.
You can exploit the safety potential of the fail-safe option
by at least programming the throttle channel to respond
to a fail-safe situation: the throttle channel of an engine-
powered model should be set to idle, the throttle channel
of an electric-powered model to “stop”, and the throttle
channel of a model helicopter to “Hold”. If interference
should occur, these settings will help prevent the model
ying out of control, possibly causing personal injury or
property damage.
IMPORTANT:
The two functions “Binding” and “Range check” descri-
bed above can be used regardless of the method you
last employed to program the transmitter, i.e. using
the programming button or the SMART-BOX; neither
of these two options causes signifi cant changes to the
settings saved in the receiver. However, if you call up
the Fail-Safe function using the programming button
as described below, this resets ALL the settings of the
SMART-BOX at the Fail-Safe screen (RX FAIL SAFE)
- and this includes the settings available through the
facilities of the programming button. At the same time
the Country setting will revert to Universal if you have
previously selected “France” using the programming
button. You MUST therefore select the Country setting
again if necessary. For this reason, wherever
