Security Code Screen
If you are concerned about unauthorized changing of Trip
500AL settings, you may enter a security code from the
DriveRight Vehicle Management Software. The Trip 500AL
will not allow access to the rest of the settings screens until
the correct 4-digit security code is entered. The unit allows
five attempts to enter the correct security code before
returning to the Current Readings screen and activating the
tamper indicator (pressing MODE to move to the next set-
tings screen is considered an “attempt”). The time and date
of the unsuccessful tamper attempt is stored and may be
viewed using the DriveRight Vehicle Management Software.
NOTE: Use security code 0000 (four zeros) if you do not want to
password-protect calibration, since the unit defaults to that
code when first displaying the Security Code screen.
Security Code Screen
You have the following options from the Security Code
Screen:
❏ Enter the Security Code
The flashing digit in the code is the active
digit. Press and release PLUS or MINUS to
cycle forward or backward through the avail-
able entries for the active digit (0 to 9). To
change the active digit, press and release
SET/CLEAR. Each time you press SET/CLEAR,
the next digit becomes active. Once the cor-
rect security code has been entered, press
MODE to move to the next settings screen.
NOTE: If the entered code is correct, the clear all
log data screen appears when you press
MODE. If the entered code is not correct,
the word NO appears on the display. You
may attempt to enter the correct code five
times before the unit returns you to the
