Do not touch the equipment with hands or gloves wet with water.
Otherwise, an electric shock or a malfunction may occur.
• Do not place any object on the operation panel.
In particular, if a hot object is placed on the operation panel, it can cause
deformation of the surface of the operation panel.
• Do not apply any undue shock on the operation panel, trackball and dials.
Otherwise, a malfunction may result.
Make sure that the main power is turned off before inspection or replacement
of parts.
Otherwise, an electric shock, a fire, or a malfunction may occur.
Since the image within the previous observation range is displayed by
expanding/contracting for the period from immediately after switching of the
observation range from the next image updating, do not use this image for
navigation.
If this image is used for navigation, an accident may occur.
In the case of turning on the power under the condition of low temperature,
do pre-heat more than 30 minutes.
Otherwise, an operation failure may occur and an accident may occur.
Normally, use the automatic tuning mode.
If you use the manual tuning mode, an accident may be caused by a
transmission/reception problem.
Use the manual tuning mode only when you cannot bet the best tuning
conditions in the automatic tuning mode.
Always keep the sensitivity adjusted to the best condition.
If you raise the sensitivity excessively, the visibility of the target will be
reduced by unwanted signals including receiver noise and pseudo image.
This may cause an accident.
If the sensitivity is reduced excessively, detection of a target such as a ship
or hazardous material will be interrupted.
Adjust the preset of the observation scene according to the oceanographic
condition, with the thorough understanding of the features of the radar signal
processing setting. The optimum radar performance may not be able to be
demonstrated due to the contents of the changed setting or the oceanographic
condition at that time.
Information is displayed in addition to a warning or a caution in the alert status
area.
Information is used to report operation errors and so on to the users.
Unlike other alerts, no detail display is provided for Information.
