Precaution
Do not open the equipment, only authorized Simrad technicians are qualifi ed
to do so. There is high voltage present inside the scanner which may also be
present even after the power switch has been turned off.
Power source, fuse and power cable
The radar scanner will get its power from the display unit. Ensure that the
power cable is fi rmly attached to the appropriate port on the display unit.
Note: the appropriate fuse(s) must be employed,
see fuse rating in the
specifi cations.
Maintenance safety
Beware of residual high voltages
High voltages may remain in the capacitors several minutes after you have
turned the power switch off and disconnected the cable between the radar
scanner and display unit. Wait for at least five minutes or discharge them to
ground before starting your inspection.
Main power supply must be disconnected
To prevent electrical injury due to erroneous power switching, make sure that
the main power supply and the system power switch are both OFF. Also attach
a safety label showing that service is in progress.
Avoid inhaling dust
When cleaning inside of the equipment, avoid inhaling the dust, as it could be
a temporary health hazard.
Avoid static electricity
Take care not to damage the ESDs (Electrostatic Sensitive Devices) due to
static electricity from carpeting and clothing.
Routine check
Periodically check that the scanner’s mounting bolts are tight and not cor-
