R
WARNING! NEVER apply AC voltage to the
DC connector of the display unit. This may pose a fire
hazard, result in an electric shock or damage the dis-
play unit.
R
WARNING! NEVER apply more than 42 V DC
to the DC connector of the display unit. This may pose
a fire hazard or damage the display unit.
R

temperature below –15˚C (+5˚F) or above +55˚C
(+131˚F).
DO NOT use harsh solvents such as benzine or alco-
hol when cleaning the display unit, as they will damage
the display unit’s surfaces.
DO NOT place the display unit in areas that will block
air passage or put anything around the display unit.
This will obstruct heat dissipation.
DO NOT use the display unit near any magnetic
materials, such as a loudspeaker or a large power
transformer, as this can cause distortion of the CRT
display.

The display unit meets IPX4 requirements for splash
resistance when the supplied connection cable, scan-
ner unit are connected.
However, if it is dropped, splash resistance cannot be
guaranteed because of possible damage to the case
or the waterproof seals.
For Scanner unit:
R
DANGER: HIGH VOLTAGE! NEVER open
the scanner unit. The scanner unit contains high volt-
age that could be fatal. And there are no user adjust-
ment points. All repairs and adjustments MUST be
made by a qualified electronics technician at your
Marine Navigation Dealer.
For qualified electronics technician only:
R
DANGER: HIGH VOLTAGE! High volt-
ages of up to 3,500 volts are used in the scanner
unit. Although prudent measures for safety have
been adopted, sufficient 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! To prevent
an electric shock, turn the
radar
’s power is OFF and
do not reach inside the scanner unit until you have:
• discharged the capacitors by disconnecting the system
cable from the radar unit for 5 minutes.
• checked that no electric charges remain inside the de-
vice.
Also, it is safest to wear dry insulated rubber gloves.
NEVER use both hands simultaneously; keep one
hand in your pocket.
R
WARNING: RADIATION HAZARD!

beginning work on the scanner unit.
DO NOT use or place the scanner unit in areas with
temperature below –25˚C (–13˚F) or above +70˚C
(+158˚F).
NEVER immerse the scanner unit in the water.
The scanner units meet IPX6
*
requirements for high-
pressure water jet resistance.
However, if these items are dropped, high-pressure
water jet resistance cannot be guaranteed because
of possible damage to the cases or the waterproof
seals.
*
Except for the cable connectors. They meet IPX4 require-
ments while connecting to the radar unit.
