Life of Parts

Magnetron

When a magnetron reaches the end of its life, target echoes become weak and do not 
appear on the display. If long-range performance appears to have declined, contact 
your dealer about replacement of the magnetron.

Antenna Motor

When an antenna motor reaches the end of its life, the antenna’s rotation may stop or 
abnormal noise sounds from the antenna unit. If such symptom occurs, contact your 
dealer about replacement of the antenna motor.
