MOUNTING

Bottom Discrimination Sounder

Do not apply paint, rust protection, etc, to coated surface parts of the unit.
These may damage the coated surface areas.
Be especially careful not to apply chemicals to the coated connectors.
The Bottom Discrimination Sounder can be installed on a desktop, deck or on a bulkhead. When
selecting a mounting location for the Bottom Discrimination Sounder, keep the following in mind:
• Locate the unit away from areas where rain and splash can occur.
• The temperature and humidity should be moderate and stable.
• Locate the unit away from exhaust pipes and vents.
• Locate the unit where shock and vibration are minimal.
• The mounting location should be well ventilated.
• Keep the unit away from electromagnetic field-generating equipment such as motors and gen-
erators.
• Leave slack in cables for maintenance and servicing ease.
• A magnetic compass will be affected if the unit is placed too close to it. Observe the compass
safe distances noted in the safety instructions to prevent disturbance to the magnetic compass.
• Fasten the Bottom Discrimination Sounder to the mounting location with four self-tapping
screws (4×20, supplied). Fasten as specified by the drawing at the end of this book. If fastening
to an upright wall or bulkhead, mount the unit vertically, not sideways.
