Cleaning the Front Panel touch screen
The front surface of the touch screen should be kept free of dirt, dust, finger prints and
other materials that could degrade optical properties. Long term contact with abrasive
materials will scratch the front surface, and image quality will be degraded. For best
results, use a clean, damp, non-abrasive cloth towel and any commercially available
window cleaner to regularly clean the surface. The cleaning solution should be
applied to the towel rather than the surface of the touch screen. Do not flood the
surface of the touch screen. Fluid ingress may occur from behind the panel and cause
damage.
Backing up the iVDR
It is recommended that you back up your iVDR to support recovery in case of a
system fault. You can back up your iVDR using the following mechanisms:
• Software recovery disk image — Refer to “Using the software recovery disk
image” on page 50 . A software recovery disk image is a file that contains an image
of the entire system drive (C:) of your iVDR. When you restore your system drive
from this image you effectively “undo” any software faults that might have been
introduced into your system through ongoing use.
You should make an image when you first get your iVDR set up and configured for
operation in your facility. That way you can easily return the iVDR to its “like
new” state, yet with all your site-specific configurations intact. You should also
make an image immediately after you do an update of the M-Series system
software. This allows you to return to the baseline operating condition for that
version of software.
The image is stored on the second partition on the system drive and it is not
intended to be used to rebuild a failed system drive. Refer to
“Replacing an iVDR”
on page 46 for information on system drive faults.
The software recovery disk image does not include your media, but it does include
all elements of the Media File System. Therefore, when you make a software
recovery disk image, it contains a “snapshot” of the references that point to the
