you
encounter
a
problem,
first
read
the
"What
to
do
if
..."
table
(see
Table

where
the
most
frequently
asked
questions
of
the
dispenser
users
about
the
problems
encountered
at
the
fuel
station
are
described.
In
the
event
of
a
dispenser
defect,
the
electronic
counter
that
controls
the
dispenser
displays
a
fault
message
in
the
form
of
a
numeric
code.
The
fault
codes
for
the
individual
types
of
electronic
counters
are
listed
in
the
chapter

respond
to
the
removal
of

means
that
the
dispenser
is
without
the
power
supply,
or
the
delivery
nozzle
on
the
dispenser
is
poorly
hinged,
or
that
the
dispenser
is
