• Install the main switch for the sonar where it can be easily accessed. Turn off
this switch when the sonar is not being used, to reduce power consumption
and to prevent the transducer from slipping by vibration.
• For AC mains, use two rectifiers RU-1746B, one for the display and transceiver
units and the other for the hull unit.
