This could cause an electric shock or damage the
display unit.
R WARNING! NEVER apply AC voltage to the DC
connector of the display unit. This could cause a re
or damage the display unit.
R WARNING! NEVER apply more than 42 V DC
to the DC connector of the display unit. This could
cause a re or damage the display unit.
R WARNING! NEVER touch or operate the display

R
DANGER: HIGH VOLTAGE! High voltages of
about 3,500 volts are used in the scanner unit.
Although prudent measures for safety have been
adopted, sufcient care must be taken in the
operation, maintenance and adjustment of the
scanner unit.
Electric shock of 1,000 volts or more may cause
electrocution and death; even an electric shock of
only 100 volts may be fatal.
R DANGER: HIGH VOLTAGE! DO NOT turn OFF the
radar
’s power and do not reach inside the scanner
unit before you have:
• discharged the capacitors by disconnecting the

(+158˚F).
NEVER immerse the scanner unit in the water.
The scanner unit meets IPX6
*
requirements for high-
pressure water jet resistance.
However, if the scanner unit is dropped, high-
pressure water jet resistance cannot be guaranteed
because of possible damage to the cases or the
