• No obstacle should be in the fore direction since it causes a shadow zone and aerated
water, resulting in poor sonar performance.
• The physical distance between the hull unit and the transceiver unit should be no more
than 5 m.
• The space shown in the figure on the next page is required around the hull unit for wiring
and maintenance.
• If the ambient temperature around the unit will be below 0°C, provide the sonar
compartment with a heater to keep the temperature above 0°C.
Note: After mounting the equipment, install anti-vibration stays, referring to page 1-7.
