Actions to be taken every month
Once a month we recommend that you inspect and clean the various main units comprised by the SN90 system.
1 Inspect the sonar room. Make sure that the ambient temperature in the room meets the environmental specifications.
2 Inspect and clean the display.
3 Inspect and clean the Processor Unit.
4 Inspect and clean the Operating Panel.
5 Inspect and clean the Transceiver Unit.
6 Inspect the Hull Unit. (if applicable)
A hull unit may be provided as an option. It allows you to lower and hoist the transducer. All information and tasks related to the hull unit may be disregarded and omitted if the SN90 system is installed without this unit.
