About the sonar room
The sonar room is the compartment in which the Hull Unit is installed.
Other system units may also be installed in the sonar room. These are typically a Transceiver
Unit and/or a Power Supply Unit.
It is strongly recommended to use a dedicated compartment to house these units. They must
also be installed relatively close to each other due to the limited length of the cables.

Environmental requirements
The MF90 system units must be installed in a dry and dust-free environment. The units are
not fully protected against humidity, dust or moisture.
It is important that the sonar room is kept clean and dry. The system units must not be
exposed to excessive temperatures, dust, moisture or humidity. Such conditions can cause
corrosive attacks and subsequent failures to the electronic circuitry.
Make sure that installation or maintenance of other equipment in the sonar room does not
affect the MF90 system units. The use of heavy tools in the sonar room must be avoided.
This includes welding equipment, saws, hammers or similar hand or electrical equipment.
