Static electricity, electromagnetic radiation and other electrical phenomena can cause
corruption or loss of data stored on the CF card. For this reason, you should always make
backup copies of important sound files on other media such as computer hard disk or CD.
CF card problems can usually be corrected by formatting the card. Formatting a CF card
deletes all information stored on the card, including sound files and profiles. Before
formatting a card you should copy all files you wish to keep on other media. If you plan to use
the D500X where you don’t have access to other storage devices, it is a good idea to take
along a few extra CF cards just in case you experience an unexpected CF card problem.
Formatting is recommended for any CF card that you suspect contains corrupted files or for
newly purchased CF cards.
Caution. Formatting a storage medium erases all data previously stored. Make
sure you don’t inadvertently format a card or other storage device that contains
data you wish to retain!
Using more than one CF card
The D500X can use up to four CF cards. The first card must be located in slot #1 and the next
in slot #2 etc. The CF card indicator on the display shows the remaining total space on all of
the cards. When the unit is set up for an automatic (level-triggered) recording session, all the
CF cards should be newly formatted (i.e. not contain any previous recordings).
The switching between cards is made automatically. When the remaining space on the current
card is not enough to make another recording with the current settings (sampling frequency,
file length) and the unit is used in the automatic (level-triggered) recording mode, it switches
to the next card and makes the next recording there. If the detector is used in the manual
recording mode, it is not always possible to know the recording length on beforehand. In this
case, the unit switches to the next available CF card if there is less space than 10 seconds at
the chosen sampling frequency. This means that if the remaining recording time is e.g. 15
seconds and you attempt to make a recording of 20 seconds, this recording will be interrupted.
The active CF card (the card currently used to make recordings to) is shown on the display
before the file name. The remaining space on the active CF card is shown after the file name.
Choosing CF card type
SanDisk CF cards should be used. We have successfully
tested SanDisk Ultra, Ultra II, Extreme and Extreme III cards
in sizes up to 32 GB.
In order to make it easier to remove a CF card from the
D500X, a small “handle” can be made with a piece of tape
(see the picture).
