FlashDrive should be unplugged or any key pressed.

”Automatic write of registered data”
- this option allows activating of automatic data
storage to the Flash Drive plugged to USB socket.
Automatic data writing is made periodically, after recording about 70 kB of new data,
what keeps the usage of internal memory below about 1%.
Autostorage frequency depends on recording settings (number of channels, and
recording period). Minimum period between successive data storages is about 50 min. (8
channels recorded every 1 sec.).
•
In case of error while auto data writing, device displays a proper message and
waits for user acknowledge. While waiting for acknowledge,
DEVICE DOES
NOT EXECUTE ANY AUTOSTORAGES
, but all data is recorded to internal
memory of the device. Due to the possibility of occurrence of: write error,
FlashDrive or USB malfunction, and other incidental problems, autostorage
function should be controlled by user from time to time. Lack of control can
cause overwriting of data in internal memory or stopping of data recording due
to impossibility of data storage on FlashDrive.
•
If “
Password for USB disk write
” parameter has been set, then after power
off / on sequence it is necessary to enter this password to run “Auto data write”
function. To omit this requirement it is recommended to use function “

” or disable of “
Password for USB disk write
”.
•
While “Auto data write” is active and FlashDisk is plugged to USB connector,
pressing the
[ENTER]
key in any presentation mode will force the storage of
current data to the Flash Drive (other functions of
[ENTER]
key are disabled).
To allow default functions of
[ENTER]
button, it is necessary to unplug Flash
Drive from USB connector.
•
Depending on the recording settings, periods between successive storages can
be long. To be sure that current data (up to now) had been written, force data
storage (pressing
[ENTER]
in any data presentation mode) before disconnecting
the Flash Drive from USB (see the previous note).
