1.3 Maintenance
Perform unmount operation before extracting an SD card (USB memory).
Android operating system caches data when reading or writing SD card (USB
memory) data. If you do not unmount the SD card and extract it, the cache data is
not written back to the USB memory causing to damage the SD card. Android
operating system unmounts memory devices when it is shut down.
When you insert an SD card (or USB memory), make sure that it is mounted.
SD card (or USB memory) may not be mounted automatically when you insert it.
Especially in maintenance operations, please confirm whether the SD card is
mounted or not when you insert or extract it before the operation. On V-R100, Z
report data is not stored in an SD card if it is not mounted.
SD card (USB memory) is not unmounted just by the main power switch off.
SD card (or USB memory) is not unmounted when you turn the main power switch
off without unmounting it. SD card may be damaged if you turn the powe switch off
and extract it without unmounting.
Especially, the SD card (USB memory) is damaged with high probability if you
change it without unmounting after the power off.
Shut down the system after using the Machine.
If V-R100 or V-R7000 is not used for a while, do not turn the power off without
shutting down the system. Please shut the system down then turn the power off.
Otherwise an unmounted SD card or USB memory may be damaged.
1.4 Operation
Do not turn the mains power off during a finalization or a Z report operation.
The unit updates the database of details during finalization operation (from
finalization key depression to receipt issue completion). Do not turn the power off
while finalization operation is in process.
Also during Z report operations (from starting Z report operation to completing Z
report print), the unit creates sum data from the database of details. Therefore
please do not turn the mains power off during Z reporting operations.
It is necessary to mount an SD card for storing Z report data.
For V-R100, Even an SD card is inserted in the card slot of the unit, Z report data is
not stored if it is unmounted. If an message noticing that an SD card is not inserted
is shown, please confirm that an SD card is inserted.
V-R7000 or V-T500 has Internal Storage then you do not have to care it.
