CAUTION
When setting a guard zone, make sure to properly adjust gain,
sea-surface reflection suppression level, and rain/snow reflection
suppression level so that the optimal target images are always on the
radar screen. The guard zone alarm will not be activated for targets
undetected by the radar, and it may result in accidents such as
collisions.
The simulation function is used exclusively for deciding whether or not
target tracking is properly operating. Therefore, never use this function
unless you wish to check target tracking operations.
Note especially that, if this function is used during actual navigation,
simulated targets are displayed and may become confused with other
actual targets. Therefore, never use this function during actual
navigation.
Optimal values have been set for VD LEVEL and CONSTANT; therefore,
never change their values unless absolutely necessary. Failure may
result in accidents that would lower target tracking performance.
Make sure to shut off the main power before replacing parts. Failure
may result in electric shock or equipment failure.
When replacing magnetrons, make sure to shut off the main power and
let the equipment stand for more than 5 minutes to discharge the
high-voltage circuit. Failure may result in electrocution.
Make sure to take off your watch when your hand must get close to the
magnetron.
Failure may result in damage to the watch since the magnetron is a
strong magnet.
Make sure that two or more staff member work together when
replacing the LCD. If only one person attempts to replace the LCD,
he/she may drop it and become injured.
