Symptom Possible Cause and Solution
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)
Diagnostic Display. If the voltage display is turned OFF, go to the “Diagnostic
Display Menu” on page 2–9 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.
The DVR does not power on. • Is the internal temperature below 40°F (4°C)? The TEMP LED on the front panel will
be flashing.
