Starting up the transmitter

Preliminary remarks

Theoretically, the Graupner-HoTT system allows more
than 200 models or remote-control systems to be op-
erated at the same time. This number will be signifi -
cantly less in practice since permits are required for
combined remote operation within the 2.4 GHz ISM
band. The ultimate limiting factor should be overall the
dimension of the available fi eld.
Battery charged?
Since the transmitter is delivered with a partially
charged battery, you will need to charge it observ-
ing the charge instructions included in the Part 1 of
the manual. Otherwise, a warning signal will sound
after a short time, and a related message will appear
in the basic display after the voltage drops below a
certain threshold which can be changed in the line
"Batt warning" in the sub-menu "ETC.

Transmitter startup

After the transmitter is switched on by a motor pow-
ered fi xed wing model the actual control impulse of
the output 1 or by helicopter model the throttle ser-
vo or rpm controller connected to the output 6 are
checked. If this impulse is outside a specifi cally se-
lected band width for idle and then there is the danger
that the motor can start, the RF module remains off
for safety reasons.
4 Starting up the transmitter
In all other cases by switching on the transmitter the
RF module will be switched on too and in the center
of the display it will appear the message:
At the same time, audible warning signals sound for a
few seconds.
You now have the option of waiting a few seconds
until the display disappears automatically or maintain-
ing the HF transmissions by manually tapping the
button, or switching them off by tapping the
button.

You can turn off a receiver that is on and then fi rst
touch ON for demonstration purposes. You are then

The green "TX" and white "RX" on the left and right
of this switch symbol mean that the currently active
model memory has once been linked to a Graupner-
HoTT receiver but is presently not linked.
Once this link exists, the fi eld strength display ap-
pears to the left of the green "TX" and to the right of
the white "RX", and the numeric display underneath
shows the current voltage of the receiver power sup-
ply, for example:
