release the slot's latch then pull out the memory card.
Data acquisition / storage
The storage of data on the SD card is coupled to the
fl ight timer. If this timer is started – when a suitable
memory card is inserted in the card slot and a
telemetry link to the receiver exists – data acquisition
is also started. Data acquisition will stop again when
the fl ight timer is stopped. The fl ight timer is started
and stopped as described in the section "Timers
(general)" on page 153.
While data acquisition is ongoing, the on-screen card
image will blink continuously at a slow rate.
The amount of data written on the memory card is
presented as a black bar graph which grows from left
to right as data fi lls the memory card.
After a data acquisition session is fi nished, there
will be an (empty) folder "Models" and a "LogData"
folder on the memory card. Within the "LogData"
folder there will be log fi les in sub-folders that are
designated with names in the format 0001_year-
month-day.bin, 0002_year-month-day.bin, etc. If a
model memory folder is still "unnamed" when the
memory card is removed from the transmitter and
inserted into the card slot of a PC or laptop, the
respective log fi les can be found in a sub-folder
designated "NoName". There is a PC program
available on the transmitter's download web page at
www.graupner.de with which the stored data can be
evaluated on a compatible PC.
Importing voice fi les
As mentioned in section "Headsets", here at the right,
the transmitter's acoustic signals as well as those
signals and announcements associated with the
telemetry menu can be output by way of the headset
connector. These announcements are made in
German language by default. These announcements
are summarized in a voice packet which is stored in a
transmitter-internal memory but can be replaced by a
24 General operating notices - Face-side connections
voice packet of a different language at any time. More
information about this can be found in the section
»SECRET MODE« beginning on page 32.
Importing/exporting model memories
Any model memory can be stored to an inserted
memory card or from an inserted card into the
transmitter. This feature is intended to support data
exchange between identical transmitters or even use
as data backup. More information about this can be
found in the section »Copy / Erase« beginning on
page 71.
Note:
Some special symbols that can be used in model
names are subject to specifi c restrictions associated
with the FAT or FAT32 fi le system used by the
memory cards and these special symbols will be
replaced during the copy process with a tilde (~).

Headset connector

Once the right face-side cover has been moved away,
mc-20
the HoTT transmitter's headset connector is
accessible:
The jack is intended for connecting conventional
earplugs or a headset by way of a 3.5 mm TRS
plug. (not included in the set) An appropriate symbol
will appear in the basic display when a headset is
connected.
