Display Lamp
To read the Trip 500AL at night, use the display lamp. To
toggle the display lamp on and off, press PLUS when view-
ing the Current Readings screen. Be aware that the display
lamp does not work when the unit is operating on battery
power.
NOTE: The display lamp automatically shuts itself off after 10 min-
utes if the vehicle is stopped.
Restarting the Trip 500AL
If Trip 500AL display “locks up,” you may restart the Trip
500AL by pressing and releasing MODE and PLUS at the
same time. No log data, settings, or code information is lost
when you restart the unit.
NOTE: The tamper indicator will appear if you restart the unit in this
way, provided you use a security code other than 0000.
T ROUBLESHOOTING G UIDE
While the Trip 500AL is designed to provide years of trou-
ble-free operation, occasional problems may arise. If you are
having a problem with your unit, please check the following
guide before calling the factory. You will be able to solve
many of the problems yourself. If, after checking this guide,
you are still unable to solve the problem, please call the fac-
tory at 1-510-732-7814 for further instructions. You may
also check the support section of our website (www.davis-
net.com) or send e-mail to tech support (support@davis-
net.com).
Please do not return your unit for repair without prior
authorization.
Many of the troubleshooting suggestions below relate to the
positioning of the magnet and sensor in driveshaft mounted
Trip 500AL units. If you have a VSS version, you should
ignore these suggestions.
NOTE: We will be glad to answer any questions you may have
regarding the operation of the Drive-Right unit itself. We can-
not, however, answer any questions relating to the installa-
tion of the unit in your vehicle.
