is actually required. To copy the files to an SD card in the
required order, proceed as follows:
1) First, always make a backup copy of the original files that
are stored on the memory card!
2) Reformat the SD memory card.
3) Select /Copy the 16 kHz file ("16kHz.mp3") and save the file
to the root directory of the SD memory card (drag & drop).
Note: MEVAC-4 uses the 16 kHz tone for testing purposes. Always
use the original file supplied.
4) Select /Copy the preliminary microphone chime file (e. g.
"2-GONG.mp3") and save the file to the root directory of
the SD memory card (drag & drop).

A slot for standard SD memory cards
(Secure Digital) is located inside the
unit.* All announcements and sig-
nal sounds are stored in MP3 format
on the SD memory card. A sampling
rate of 256 kBit / s, 44 kHz mono is
recommended. Other formats are
also supported.
* Note: Older versions of MEVAC-4 may
alternatively include a slot for multimedia
cards (MMC). When replacing a defective
MMC card, note that, due to modified
specifications by the card manufacturers,
MMC cards manufactured after 2008
cannot be used anymore.
5) Select /Copy the alarm file (e. g. "ALARM.mp3") and save
the file to the root directory of the SD memory card (drag
& drop).
6) Select /Copy the preliminary alarm file (e. g. "ALERT.mp3")
and save the file to the root directory of the SD memory
card (drag & drop).
7) Select /Copy the text file (e. g. "TEXT1-5.mp3") and save
the file to the root directory of the SD memory card (drag
& drop).
8) Select /Copy the preliminary fireman's microphone chime file
(e. g. "F-SIRENE.mp3") and save the file to the root directory
of the SD memory card (drag & drop).
Always observe this procedure as this is the only way to
make sure that the data is stored on the memory card in the
correct order. The MEVAC-4 system will recognize the signals
by their order and not by their names. The names are for your
information only.
To check the order of the MP3 files on the memory card,
proceed as follows:
1) Press the red button PROGRAM.
2) Press the button T4.
The display of the MEVAC-4 system will indicate, one after
the other, the number of the storage location and the name
of the corresponding MP3 file.
When a file is reproduced during normal operation, the
display will indicate the respective storage location and the
file name (see chapter 6.2).
