Starting up the transmitter
Introductory remarks on the mz-18 HoTT and mz-24 HoTT transmitters
Theoretically, the Graupner-HoTT system allows
more than 200 models or remote-control systems to
be operated 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. Generally however, more models can be operated
at the same time within the 2.4 GHz band than was
previously the case within the conventional 35/40 MHz
frequencies.
Battery charged?
Since the transmitter is delivered with an uncharged bat-
tery, you will need to charge it observing the instructions
on page 15. Otherwise, a warning signal will sound
after a short time and a related message will appear
in the basic display after a certain voltage is reached
(normally 4.8 V with the mz-18 HoTT transmitter and
3.6 V with the mz-24 HoTT transmitter) which can be
changed in the line "Bat. warning threshold" in the sub-
menu "Etc.Set" page 202, within the system menu.

Transmitter startup
As of fi rmware version V 1.023 or higher, switching on
the transmitter in the as-delivered state generally also
activates the HF transmissions and the display appears
in the centre of the transmitter display as previously:
Warning
Thr.HOLD
Thr.POS
Thr.CUT
QLink
Please select RF ON/OFF
ON
Normal signal
OFF
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 maintaining the
HF transmissions by manually tapping the ON button
with your fi nger or the provided stylus, or switching them
off by tapping the OFF button.
You can switch off a receiver that is on and then fi rst
touch ON for demonstration purposes. You are then in
the basic display of the mz-18 HoTT or mz-24 HoTT
transmitter:

The blue switch symbol at the top left between the red
"RX" and the green "TX" means that the high-frequency
transmission of the transmitter is on.
The red "RX" and green "TX" 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 appears
next to the red "RX" and right next to the green "TX",
and the yellow numeric display underneath shows the
current voltage of the receiver power supply, for exam-
