How to resolve the error
 Clean all optical components
through which the laser beam
passes
 Check and correct the alignment of
the transmitter unit in relation to
the receiver unit
 If the error occurs repeatedly or
continuously: Have the error re-
solved by authorized service per-
sonnel
 Clean all optical components
through which the laser beam
passes
 Remove any foreign matter that
may be present and that may in-
terrupt the transmission of the la-
ser beam
 Check and correct the alignment of
the transmitter unit in relation to
the receiver unit
 Remove any foreign matter that
may be present and that may in-
terrupt the transmission of the la-
ser beam
 Check that the transmitter unit
and receiver unit are securely in-
stalled
 Check and repair the electrical
connection between the transmit-
ter unit and receiver unit
 Reduce the measurement period
for determining the average value
 Check and repair the electrical
