Troubleshooting

NOTICE!
A
Stop the vehicle immediately and investigate the situation (getting
out if necessary), if the following happens while you are manoeu-
vring:
when manoeuvring, the device first indicates an obstacle and the
tone sequence speeds up normally (e.g. from slow to medium).
Suddenly the signal tone slows down, or no obstacle is indicated at
all.
This means that the original obstacle is in the blind spot of the sen-
sors (construction-related characteristic), and it is possible to hit it.
