To check the power cables, and connections:
•
Check the power outlet or power strip with an item that you know is functioning
properly. A lamp or radio is a convenient item for checking the power. You may also
need to check the fuses and breakers in your electric box.
•
If the outlet is controlled by a wall switch, make sure that the switch is on.
•
If the outlet is controlled by a dimmer switch, use a different outlet.
•
If your Digital Video Recorder is plugged into a power strip with an On/Off switch,
make sure the switch is on.
1. With the Digital Video Recorder's power switched off, check all cable
connections. If the Digital Video Recorder is connected to any peripheral
devices, look for loose or disconnected cables. If the Digital Video Recorder
is too close to a wall, a cable connection may be loose or the cables may be
crimped.
2. When you are certain that you have power available and all connections are
good, turn the Digital Video Recorder on again. If the Digital Video Recorder
still does not start, you may have a hardware problem.
Do not substitute the Digital Video Recorder's cable with another cable from a different
type of device even if the cables look exactly the same. The wiring inside the cables may
be different
The Power-On Self Test
The Power-On Self Test (POST) runs every time you turn on or reset the Digital
Video Recorder. The POST checks memory, the main system board, the display,
the mouse, the disk drives, and other installed options.
A few seconds after you turn on your Digital Video Recorder, a copyright message
appears on your display screen. A memory test message appears next; as the test
continues, memory size increases until all installed memory is tested.
Two classifications of malfunctions can be detected during the POST:
Error messages that indicate a failure with the hardware, the software,
or the Basic Input/Output System (BIOS). These critical malfunctions
prevent the Digital Video Recorder from operating at all or could cause
incorrect and apparent results. An example of a critical error is CPU
malfunction.
Messages that furnish important information on the power-on and boot
processes (such as memory status). These non-critical malfunctions
are those that cause incorrect results that may not be readily apparent.
An example of a non-critical error would be a memory chip failure.
