Operation Manual

9.15. Remote Control Output (Optional)

The FMD55 can be supplied with an output for control from an

external relay. The control output works parallel to the backlighting

of the display. This switches off automatically in the stand-by mode

and, depending on the setting, switches on automatically in the

timer mode.

9.16. Adjusting Contrast of LCD Display

The contrast of LCDs is generally dependant on temperature

fluctuation. The FMD55 has an integrated compensator, which,

through a wide range in temperature, enables a rich in contrast

display. However during a greater fluctuation it is sometimes

necessary to adjust slightly. Before adjusting, the unit should have

completed the warming up phase i.e. working for about one or two

hours. Adjust, using the screwdri ver supplied, the small screw to the

right and above the volume control knob.
