3.4 Updating System Software
If the system software of the 16CH DVR needs to be upgraded, please take the following steps to safely
update it.
Important: Before carrying out the following procedures, please ensure the SD card is working
and the system software file is intact.
1. Create a directory named DVRVIDEO in the SD Card; if you already have a directory, move to Step2.
2. Copy the file of UPDATE.BIN to the DVRVIDEO-directory.
3. If 16CH DVR is running, please power it off first.
4. Insert the SD card into the built-in SD slot of the unit.
5. Hold down the Up and Down buttons simultaneously, and then turn on the unit while still
holding down the buttons.
6. Keep holding down the buttons until the 16CH DVR sounds a note and displays the message “ LOAD
PROGRAM . . .” Now the 16CH DVR is updating the system software, taking approximately 150
seconds to complete.
7. Restart the unit by turning off the DVR when the device displays the message “ PLEASE POWER OFF
RESTART”. Then turn on the DVR again. The process is complete.
(If you have already followed procedures 1~6, 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 repeat procedures 1 ~
6.)
8. Verify the version information of the system software. (Please refer to the section 5.7 DEFAULT
SETTING option)
Warning: Don't interrupt the process or use an SD card lacking the proper system
software, as this could damage the unit.
