Please take the following steps to safely update
the system software.
1.
Turn off the DVR.
2.
Insert the SD card into the built-in SD slot of the
unit.
3.
Turn on the DVR.
4.
The DVR sounds a tone and displays the
message “

”. Now the

take approximately 90 seconds to process.
5.
The DVR displays the message “
PLEASE
REMOVE SD CARD
”. The process is complete.
Please remove the SD card, and the DVR will
restart automatically. (If you have already followed
procedures 1
~ 5 and the unit is still unable to turn
on, then please first check if the SD card you are
using is functioning and the file is intact. And then
start procedures 1 ~ 5 all over again.)
6.
Verify the version of the system software (please
refer to the section

Caution

1. Before carrying out the updating procedures, please
ensure the SD card is working and the file of the
system software is intact.
2. Don’t Interrupt the process while the unit is updating
itself, as this will cause the unit to crash.
