Storage Media
It is recommended that only storage media provided by SIGMATEK
(CompactFlash cards, microSD cards etc.) be used.
The number of read and write actions have a significant influence on the
lifespan of the storage media.
Il est recommandé d’utiliser uniquement les supports de stockage fournis par
SIGMATEK (Cartes CompactFlash, cartes microSD, etc).
Le nombre de lectures et d'écritures ont un effet significatif sur la durée de vie du
support de stockage.
Buffer Battery
The exchangeable buffer battery ensures that programs and data in the expanded
memory (SRAM) as well the clock time (RTC) are preserved in the absence of a supply
voltage. A lithium battery is installed at the manufacturer.
The battery has enough capacity to preserve data in the absence of a supply voltage for
up to 2 years.
We recommend however, that the battery be replaced annually to ensure optimal perfor-
mance.
