The Trooper TL is designed for high reliability of operation. If you have any problems
with your system, however, read this chapter. If you cannot resolve the issue, contact

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). 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.
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.
• Is the constant and switched power harness plugged into the DVR securely?
• Are the fuses on the power supply cables blown?
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 temperature below 40°F (4°C)? Check the temperature display on the main menu. See the
Diagnostic Display menu. Wait for the DVR to warm up and start recording.

VLoss event indicated
when all cameras display
When A DVR is installed with less than the full complement of cameras connected, unused camera
input settings must be disabled to prevent the DVR from generating Video Loss (VLoss) events for
those camera inputs. In the DVR Configuration menus, disable unused camera inputs as follows:
• Record Settings menu: Camera Speed OFF, Camera Audio OFF (to save disk space)
• Record 2 Settings menu: Camera Speed OFF
• Alarms/Signals menu: Channel Speed OFF.
