Troubleshooting
Video film does not display smoothly (“jerking” image):
1. Make sure that you are using a USB-2 cable to connect the device to the computer.
2. Make sure that the device is connected to a USB 2.0 High Speed port in your
computer. Verify that the CPU Chipset’s drivers correspond to this requirement.
3. Make sure that you are using a suitable graphics card, preferably the latest generation
of nVidia
®
or ATI
®
products.
4. Update the drivers of the graphics card to the latest available at the manufacturer’s site
5. Perform a full-system virus and ad-ware/spyware scan and hard-disk defragmentation
6. Lower the resolution or color depth of your computer monitor via the Settings tab under
Control Panel > “Appearance and Themes” > “Display”.
7. Adjust your screen refresh rate in Control Panel > “Appearance and Themes” >
“Display” > Settings > Advanced > Monitor.
8. Use an nVidia
®
Ver. 2 MPEG 2 decoder or a more advance version of this product.
Signal quality is not satisfactory:
1. The
Cat’s Eye
USB 3560 device receives all its power input from the USB 2.0 High
Speed port in your computer. It is possible that insufficient power supply causes
unsatisfactory signal quality. To verify and correct this situation, proceed as follows:
a. Connect the
Cat’s Eye
USB 3560 device to another USB 2.0 High Speed port
on your computer. Compare the signal quality received on each port. Leave
the device connected to the port in which a better signal is produced.
b. If connecting the device to each of your USB 2.0 ports results in zero or poor
signal quality and/or lack of video image, use a USB 2.0 Hub with an external
power source to connect the device to the computer.
2. If, after verifying a correct power transfer to the device, the signal is too weak, use
VBox’s SignalMeter utility (included in the Installation CD-ROM’s Utilities folder) to align
the antenna according to the maximum signal strength measured.
3. If the signal is too strong, it is recommended for you to consider the following
alternatives:
•
Use the VBox SignalMeter utility to align the antenna according to the
maximum signal quality measured.
•
Use an attenuator between the antenna and the tuner.
•
Reduce the amplification, in case you use an antenna with regulated
amplifier.
