RESILIENT KEYBOARD CONTROL
The resilient-keyboard control, located to the left
of the impression control indicator, provides the op-
erator with a means of varying the resistance of the
key levers to suit her touch (Figure 6). This added
resistance is supplied by flat springs, mounted in the
path of travel of the keylevers. and is determined by
varying the position of the flat springs. Three major
settings are available to the operator:
1. L - No flat spring contact.
2. M - Some flat spring contact.
3. H - Maximum flat spring contact.
