Tune control
• AUTO — the default mode. The radar tunes itself
automatically on all range scales. Raymarine
recommends that you leave the tune function in
AUTO mode to receive the maximum signal.
• MANUAL — enables you to manually set the
tuning. Adjust the control to obtain the maximum
signal strength. If you adjust the setting shortly
after powering up the radar scanner, you should
adjust it again approximately 10 minutes after
powering up the scanner, as the required setting
will change after the magnetron has warmed up.
The radar tuning control enables you to îšżne-tune the
radar scanner’s receiver for maximum target returns
on the display.
