A constant vertical wobble appears down the screen.

TROUBLESHOTING

A constant vertical wobble appears down the screen.

∙The CAT-5 cable connecting the Local and Remote Units could be located too close to a strong power source. Reroute the cabling if possible.

∙If interference is from strong signals from a nearby broadcast transmitter, a beat pattern will appear. Change the vertical refresh rate on the monitor slightly, such as from 60Hz to 70Hz.

Picture on monitor is black and white, not color.

∙The Video cable was not attached to the PC when it was booted. Reboot the PC.

Microsoft Windows or NT will only boot into low-resolution graphics mode.

∙If your graphics card supports VESA DDC (Display Data Channel), configure the graphics driver by explicitly indicating which make and model of monitor you have rather than by using DDC.

No sound at the remote units speakers or headphones.

∙Audio cable loose or defective.

∙Audio cable in the wrong connector.

∙Sound card “Line Out” muted.

∙

No sound at the CPUs speakers when using a Microphone on the remote unit.

∙Microphone cable in wrong connector.

∙Sound card “MIC” input muted.

∙Microphone signal not amplified; increase sound card amplification by 20db. Add “MIC” jumper on remote units daughter board to increase signal. Do not add this jumper is the microphone is already a powered microphone.

CrystalView Rear Connectors INPUTS/OUTPUTSStep 1 Setting the Cable Length Jumpers InstallationINSTALLATION INSTALLATION TIP If you are using a cable that is close to the top end of the cable length range and a Video resolution of 1024 x 768 or higher, you may achieve better Video quality by selecting the jumper settings for the next higher cable length range. For example, if your CAT5 cable length is 250 feet, you might achieve better Video quality if you set jumpers JP3, JP4, and JP5 to the 301 - 600 setting. Likewise, if you are at a cable length of 500 feet, a setting of 601 - 1,000 might provide a better Video qualityFigure 4.
