WARNING:
The DVR uses the time and date to index video on HDD that is how you find and view the images later. Changing time and
date can cause the DVR to work improperly when you try to play back video. If you set the hour ahead, this is not a problem. But if you set
the hour back there will be more than one recording at same time. Therefore, you need to be careful to date and time setting. If the time is
incorrect when you install the unit, then we recommend you to set the time immediately.
3.2.2 System Shutdown
To turn off the power, press the power button for proper shutdown of the system. Do not turn off the power by pulling the power plug.
Caution
In case the power plug is pulled off while the system is operating, the currently recording file may not be closed properly. In
addition, even though index file is not damaged, index information required for quick file search may be not saved. Therefore,
turn off system power by pressing the power button to prevent malfunction.
3.2.3 Countermeasures after abnormal shutdown
The DVR has been designed to operate for long periods without a problem.
The operation of the system can be locked up however, when major parts (such as hard disk) function abnormally due to external electric
shock, physical damage, or other various reasons.
The system stops operating during abnormal situations, and the internal watchdog circuit is activated in order to reset the system for
rebooting within 10 seconds. The system will then recover normally. However, if major parts (such as hard disk) are physically damaged, it is
impossible to recover normally. This will cause continuous rebooting by watchdog or deadlock without reset.
