5. TROUBLESHOOTING
5.0 The Radar page is not available
Configure the I/O setup. Enter the I/O Connections menu, see procedure at Par. 2.7 and
select the Radar on the serial port to which the Radar is connected.
5.1 The message "Turn Radar On" is displayed on the Radar window
· Check the Radar On/Off switch. It is in the off position or has not been wired.
· Verify that the correct serial port is set in the I/O Connections menu, in case try setting
the Radar on another serial port (following procedure shown at Par. 2.7).
· Check that the Radar is connected to the chart plotter, to the same serial port as set
in the I/O Connections menu, in case try connecting it to another serial port.
· Verify that all the connections in the Junction box are done properly.
· Verify using a Voltage Meter that the Radar power supply level at the Junction Box is
at least 12V. The Radar is able to operate with 10V but some volts may be dropped due
to the cable length.
If everything above is correct, try shortening the green and the blue cable coming from the
Radar. If the Radar still doesn’t work you need to call the Standard Horizon Marine Product
support for assistance at (800)767-2450 for assistance.
5.2 After the Radar On/Off Switch is turned on the “Radar warming up”
window counts down but restarts counting down over and over.
The power supply level is too low. This may be caused by battery low, cable too long, cable
section to narrow.
5.3 Too much clutter near the Radar screen center
This is a typical phenomenon with Radar. Echoes from nearby vessel may hit other objects
like other vessels or other objects randomly and reflections can be received by Radar
antenna due to very short distance between the objects. This is normal condition in a port
where nearby targets (such as sailboat masts) may cause multiple reflections. In this case,
increase the SEA clutter and decreasing the GAIN.
If during navigation in open sea the center of the screen is covered by a large spot. If this
happens it means the most probably the Transmission Trigger Delay and/or the Main Bang
Suppression need to be correctly tuned (refer to Par. 3.1).
5.4 The screen center is always covered by a spot
The Transmission Trigger Delay or the Main Bang Suppression needs to be tuned (refer
to Par. 3.1).
5.5 After turning transmission On, the Radar page remains completely black
The Radar is probably not properly tuned. Execute the Automatic Tuning procedure to
restore optimal performance (refer to Par. 3.1).
