SAFETY INSTRUCTIONS

WARNING

Radio Frequency Radiation Hazard

The radar scanner emits electromagnetic radio frequency (RF) energy which can be
harmful, particularly to your eyes. Never look directly into the scanner aperture from a
close distance while the radar is in operation or expose yourself to the transmitting
scanner at a close distance.

Distances at which RF radiation levels of 100 and 10 W/m

 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.
