DVR
All Problems Many system problems are caused by issues with the power supplied to the
DVR. Check the following:

The voltage to the system may be too low. Check the voltage display (On or
Off). If the voltage display is turned OFF, go to the
“
Diagnostic Display
Menu” and turn Voltage Display to ON. The voltage range should be
between 8 to 32 VDC.

The power harness from the DVR must be connected as close to the battery
as possible. Check the wiring to the battery.

Check the in-line fuses and fuse holders. If a fuse is blown, determine the
cause before replacing it.

Try swapping out the DVR to see if there is any change.
The DVR does not power
on.

Is the temperature below 40
°
F (4
°
C)? The TEMP LED on the front panel
will be flashing.

Is the constant and switched power harness plugged into the DVR securely?

Are all fuses good?

Is the system grounded to the chassis?

Are the wiring connections contacting metal? No paint in between?

Is the red wire attached to a constant power source?

Is there a battery kill switch? Be sure it is not engaged.

Is the Yellow wire attached to a clean 12 VDC source that is only active
when the ignition switch is in the on position?
The DVR does not power
off. This could be due to residual voltage on the yellow wire. Check the voltage on
the yellow wire power connector, at the DVR, when the ignition is off.
The DVR turns on but does
not start recording.

Check the ignition wiring from the power input harness. Is the yellow wire
connected to an ignition switched circuit?

Is the drive installed properly with the key in the locked position on the
front panel?

Is the hard drive functioning properly? Switch the current drive with one
you know to be healthy.

Is the temperature below 40
°
F (4
°
C)? Check the temperature display on
the main menu. Wait for the DVR to warm up and start recording.

Is the temperature above 122
°
F (50
°
C)? Check the temperature display
on the main menu.

Check the battery voltage.

Check the settings for Record Delay-On time in the Record menu.

Are the timers on? Check the Timer Settings Menu. If “Enable Timers” is set
to “On”, the DVR will only record on the days and times set.

In the Recording Settings menu, is “Repeat Record” set to “Off”?
