Technical messages and errors
1
Clock Error
The VOLVO ALCOLOCK receives its
time signal from the vehicle’s tachograph.
Should the tachograph fail or be removed
for servicing, a “Clock error” message
will be displayed for several seconds. The
handset will operate correctly, but dates will
not be correctly displayed until a properly
functioning tachograph is connected.
2
Technical Error
Should the handset detect an internal power
failure “Technical error” will be displayed.
In this state, the motor can be started by
pressing the right button and turning the key
in the normal sequence. No breath test is
required when a technical error is detected.
3
Error codes
The handset will display error code 10,
20, 30, 40, 45 or 50 if a technical fault is
detected. The handset will reset to allow
the user to attempt another breath test. If
the condition persists the ALCOLOCK will
require servicing.
