1.2 How to Install the Sonar
This sonar can be installed on a deck or on a bulkhead. When selecting a mounting
location, keep the following points in mind:
• Install the unit indoors.
• The operating temperature range of this unit is -15°C to 55°C (-27°F to 99°F). Be
sure the mounting location satisfies this requirement.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away from electromagnetic field-generating equipment such as mo-
tors and generators.
• Observe the minimum recommended maintenance space shown in the outline
drawing at the back of this manual. Also, leave slack in cables for maintenance and
servicing ease.
• A magnetic compass may receive interference if it is placed too close to this unit.
Observe the compass safe distances noted in the safety instructions to prevent in-
terference to the magnetic compass.
• For mounting on a bulkhead, the connectors must face downward.
Fasten the unit to the mounting location with four self-tapping screws (5×20, supplied),
referring to the outline drawing at the back of this manual for mounting dimensions.
