Seon Maintenance and Troubleshooting Guide R004 35
The DVR is recording
intermittently.
Is the hard drive corrupted? Switch the hard drive with one you know to be
recording properly.
If necessary, reformat the original drive to see if that corrects the problem.
Check the power harness connections and condition.
Check that the ground is to the electrical system, NOT the chassis.
The DVR hangs when
powering on
Remove the hard disk and power on the unit. If the unit powers on correctly,
swap the hard drive with a good hard drive.
The DVR is on but there is
no picture on the video
monitor output.
Check the connection at the camera, as well as the connections inside the
DVR cable cover.
The voltage to the system may be too low, less than 8 VDC. If the PWR LED
on the front panel is blinking slowly; the DVR is in low voltage.
Check the power harness connections and condition.
Check the connections from the video monitor to the DVR.
You may have a problem with the camera. (See Camera Troubleshooting, “No
video display when monitor connected to DVR”).
The DVR is not recording
audio.
Check that Audio Recording is set to “On” for at least 0ne camera in the
Camera Settings menu.
The audio output on the DVR is set to channel 1 by default. Confirm which
camera is set to be the audio channel in the DVR menus.
Does your model of camera have audio capabilities?
If you are getting no live audio through your portable monitor, check that
the audio cable is properly connected and that the correct Audio Output
Channel is selected in the System Settings Menu.
(See Camera Troubleshooting for camera related audio problems).
I do not see the cameras
when connected to the
DVR
If you have a service monitor (usually in a nylon case) Check that the
monitor is charged up and switched on.
If the voltage is very low, the green light on the monitor may come on but
there may not be enough power to view the cameras.
Check camera cables.
If using a portable DVD player, again make sure the battery is fully charged.
On the supplied remote, there should be a button for switching the output
video to input video, make sure it is set as a monitor.
The DVR seems to be quite
hot to the touch
High temperatures can cause the DVR to stop recording, this is done to protect
the hard drive.
If mounted in the bulkhead is there enough air flow to circulate around the
DVR?
Take a temperature measurement at the DVR, some bulkheads on a hot day
will raise the temperature over 140 degrees F.
It may be necessary to relocate the DVR if high temperatures are causing
the DVR to stop recording.
The recorder takes a while
to start recording in cold
weather
The hard drive has an operating temperature between 32 deg F and 125 deg F.
In very cold weather when the bus is first started, the DVR has a built in heating
element that is there to warm up the hard drive. This may take time until the
hard drive reaches its operating temperature.
