[. . . ] Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table below. Note: If the scanner unit is installed at a close distance in front of the wheel house, your administration may require halt of transmission within a certain sector of scanner revolution. This is possible--Ask your FURUNO representative or dealer to provide this feature.

Post a warning sign near the switch indicating it should not be turned on while the scanner unit is being serviced. [. . . ] The oldest portions of trails are erased so only the latest trail, equal in length to the trail time selected, is shown. When the elapsed time clock counts up to 60 seconds, the elapsed time display freezes at "60, " but the latest one minute of trail are erased and then trail continuous. 3. 5 Suppressing Radar Interference Radar interference may occur when near another shipborne radar operating in the same frequency band as your radar. Its on-screen appearance is many bright dots either scattered at random or in the form of dotted lines extending from the center to the edge of the display. Interference effects are distinguishable from normal echoes because they do not appear in the same place on successive rotations of the scanner. Continuous trail The maximum continuous trail time is 99 minutes and 59 seconds. When the elapsed time clock counts up to that time the elapsed time display is reset to zero and trail begins again.
