ROUBLESHOOTING
Your Digital Video Recorder has passed through a series of rigorous quality assurance
tests to guarantee reliable performance. However, your new Digital Video Recorder is a
sophisticated piece of equipment and as such may malfunction if used incorrectly or if
one of its components fails. Included are important tips and information you will need to
help locate and solve some of the problem you may encounter.
An Approach to Troubleshooting
In general, troubleshooting involves an organized systematic approach to problem
solving. Try to isolate the problem and identify the defective device (hardware) or
improper setting (software). When you have a problem, you should do a thorough visual
inspection of the Digital Video Recorder. If none of the indicators are lit and you cannot
hear the HDD spinning, then the Digital Video Recorder is probably not receiving power.
Make sure the power cord is plugged in, and securely connected. If you are using a
power strip or surge protector, ensure that these devices are turned on.
Improperly connected cables cause often problem. If you are using peripherals such as a
mouse or keyboard, make sure they are properly connected to their respective ports.
Ensure that none of the connectors' pins are bent or broken. Check all cables connected
to the Digital Video Recorder. If any are cut, frayed, or damaged in any way, replace
them right away.
Never use a damaged cable. A damaged cable is not only a fire hazard; it may also
cause a short circuit, resulting in irreparable damage to the Digital Video Recorder.
Isolating the Problem
The problem that you will encounter can be divided into two basic categories: hardware
problem and software problem. Hardware problem can be further divided into electrical
and mechanical problem. You will know you have a hardware problem if the screen is
dark, the computer cannot read the disk drives, or you get an error message during the
Power-On Self Test (POST).
Software errors can occur at several levels. In addition, each application software
package has its own set of error messages. It is important to determine whether the
software error message you are getting is from the operating system. Once you know
this, you can refer to your dealer for a solution to the problem.
