Turn off the echo sounder otherwise it will start giving no paper alarm and that is really annoying.
Open the paper cover by pressing the paper cover open button.
Set the paper in the correct direction (Earlier days we used to cut the paper to have a triangular tip so that it rolls inside easily but now we don’t need that technique.)
Shut the cover after putting the paper roll with its tip inside.
While closing push both sides together.
Care and maintenance to keep echo sounder in good working condition.
Use a soft cloth (dry) to wipe out the dust you can also use a brush for dusting echo sounder.
Do not use solvents like thinner to clean the body.
Check frequently and make sure nuts and bolts are tight.
