6. Frequently Asked Questions
6.1 What should I do at first Radar installation?
At first installation its necessary to:
1) properly set up the Radar calibration
2) set up the I/O to detect the Radar
6.2 How can I turn Radar power On/Off
Radar power On/Off can be either directly controlled from the chart plotter or by
an external switch depending on how you have set up your chart plotter.
In case the power is managed by the chart plotter you can turn power On by
pressing [MENU] when in the Radar Page. Otherwise you have to turn power On
by acting on the external switch.
NOTE For a pratical matter we suggest to use Radar Powered On/Off controlled by
an external switch, because at a glance we can check the Radar status without
having to switch to the Radar page.
6.3 How should I setup the chart plotter to control the Radar
power On/Off?
Please refer to Chapter 1 for wiring schematic.
6.4 How can I turn Radar Transmission On/Off?
Press [ENTER] in the Radar page or enter the Radar Main Menu and set Trans-
mission On from the related menu voice. Transmission can be set in Stand-by
only from the Radar menu.
6.5 What is the preheating?
Each time you power On the Radar you must allow 90 to 120 seconds (depending
on the Radar model) to warm up the Radar. Operating the Radar before this time
could cause damage to it. For this reason the chart plotter doesn't allow operating
the Radar until the preheating is complete.
6.6 Some time the preheating takes less than 90 seconds, is
this normal?
Yes it is. It means that the Radar was already powered on at the time you turned
On the chart plotter so the preheating started before.
6.7 What is the Radar calibration?
Radar calibration is a set of options that allows to properly set the Radar to work
on your boat. You can set up the Heading correction, to compensate of orientation
errors due to the installation, the Radar trigger delay to properly adjust the Radar
beam as to correctly measure ranges, and finally the sensitivity of the Radar to
maximize the Radar sensitivity.
6.8 When and how should I adjust the Radar heading?
At first installation you should correct the Radar heading as to ensure that it is
perfectly aligned with your bow.
