Appendix 10 — Troubleshooting
Following are some frequent problems and solutions related to the DVR. Read this section before calling the dealer
or installer.
Problem: There is no image on the screen.
Solution
: Check the camera cables. If the background of the DVR system is blue, something is wrong with the
camera cable or power.
Problem: How do I access Windows?
Solution
: To protect unnecessary system crashes, Windows is blocked. See
Appendix 1 –
Accessing Windows
.
Problem: I have upgraded the software. How do I reinstall it?
Solution
: There are three steps to reinstall the software.
1. Uninstall the old version.
- Go to My Computer. Select Control Panels and the Add/Delete program, and then select the DVR model.
- The Delete button will be activated. Click Delete.
2. Scan the hard disk with the System tools under Programs/Accessories in Windows.
3. Install the new software.
Problem: The PACOM logo appears and then freezes. Sometimes the screen is black.
Solution
: There is a problem with the Main Board. Reboot the DVR. If it happens often, call your dealer or
installer.
Problem: The
Display setup is not correct
error message appears and opens up in the Windows
mode when OK is clicked.
Solution
: The DVR requires 1024x768 resolution and true color. This message will be printed on the screen when
the requirements are not met. Access Display Setup and change the values for the DVR and then reboot the system.
Problem: I am trying to change the display setup, but I cannot choose True color. The resolution
keeps jumping to a lower value.
Solution
: Some VGA cards require a few steps. Set up the resolution first. Do not worry about the color palette.
Then access Display Setup and choose True color. If it happens again, the VGA card does not support the 1024x768
resolution and True color. Change the VGA card.
Problem: The USB-serial converter has been connected to the DVR for the POS installation,
however, the dialog box asking the device driver appears.
Solution
: When connecting the POS device to the DVR using the USB-serial converter, connect the converter while
the DVR is operating. If not, the converter driver may not be operating properly and display the dialog box asking the
device driver during the system boot. However, it does not have any effect on the DVR operation. Remove the
converter, and reboot the DVR and then connect the converter again.
