Maintenance and Adjustment

Cleaning the IM-800 Front Panel Ventilation Opening

There are many small holes in the left of the front panel. Air enters here and goes out the
ventilation openings on the rear side and right side. If these holes become clogged with dust,
remove the dust with a small vacuum cleaner or other appropriate cleaning device.

Display Adjustment for DM-M820

The display adjustment procedure for the DM-M820 depends on when the unit was
manufactured.

Determining which procedure to use

Check the label on the manufacture's plate at the base of the DM-M820.
