TROUBLESHOOTING
Your Digital Video Recorder has passed through a series of rigorous quality
assurance tests to guarantee reliable performance. However, your new Digi-
tal Video Recorder is a sophisticated piece of equipment; the system mal-
function might occur if it is used incorrectly or if one of its components fails.
Included here are important tips and information you will need to help locate
and solve some of the problems 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 problems. If you are using periph-
erals 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 problems that you will encounter can be divided into two basic categories:
hardware problems and software problems. Hardware problems can be fur-
ther divided into electrical and mechanical problems.
You will know you have a hardware problem if the screen is dark, the com-
puter 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
