Never directly touch the internal components of the 
antenna, receiver/transceiver, or indicator.    Direct 
contact with these high-voltage components may cause 
electrocution.    For maintenance, inspection, or 
adjustment of equipment components, consult with our 
branch office, branch shop, sales office, or our distributor 
in your district. 
Do not get close to the radiant section of the antenna.    It 
is a rotating part, and it may cause injuries if it suddenly 
starts rotating and consequently hits the body.    It is 
recommended that the radiant section be installed at a 
high place such as on the roof of the wheelhouse, on the 
flying bridge, on the trestle, or on the radar mast so that 
no one can get close to it.    When any work must be done 
on the antenna, make sure to turn the antenna switch off.
