Display Problems
If you install a printer using the Video port on the computer, the Windows operating
system changes the screen size to 1024 x 768 pixels. The normal resolution is 1280 x 1024
pixels. This is a limitation of the Windows operating system and cannot be changed. If you
need greater resolution on the screen, you must connect to the printer using the USB or
parallel port on your computer.
If you must connect a separate monitor to the laptop, you can purchase third party cables.
You will need a VGA cable. Please note that the ultrasound images can only be optimized
for display on a single monitor.
VCR/TV Problems
If you connected a VCR or TV to the computer but the VCR or TV is not working, refer to
the owner’s manual for the specific VCR or TV. Some VCRs require you to select Line 1,
others Line 2, others Composite Video. The type of connection required is determined by
the VCR, not by the laptop or the Terason software.
The owner’s manual for the VCR should contain instructions for connecting it to various
devices, including computers and the TV.
Please note that only video output is sent to the VCR; you cannot record the audio output
of Pulsed-Wave Doppler scans.
CD Writing or Reading Problems
If you get errors when writing to a CD, check these items:
• Filenames for CDs are restricted to 64 characters, however, Windows supports
filenames with up to 256 characters. For any files that you want to archive or move to a
CD, make sure the filenames do not exceed 64 characters.
• Make sure you do not exceed the available space on the CD. For example, if you choose
100 MB to add to a CD, but the CD only has 80 MB available, the CD writer may let
you start the copying process, but will generate an error during the write process.
• If you closed the CD when you created it, you cannot add any more files to that CD.
When you copy to a CD, you can close the session, but if you want to write to the CD
again, you should not close the CD. See
Backing Up Files on a CD on page 142 for
guidelines.
If you cannot access files on a CD, you may not be able to recover those files. To avoid
possible problems reading files from a CD, follow these guidelines:
Caution: A VCR or TV installed within the patient environment may result in non-
conformance to safety standards. Use of non-medical grade peripherals
will result in non-compliance of safety and EMI standards. Non-
conformance to these standards can result in risks to the patient and
operator of this equipment.
