Function

The facsimile equipment incorporates the following firmware switch functions (WSW01 through
WSW36) which may be activated with the procedures using the control panel keys and buttons.
The firmware switches have been set at the factory in conformity to the communications standards
and codes of each country. Do not disturb them unless necessary. Some firmware switches may not
be applicable in some versions. The firmware switch data list indicates "Not used." for those
inapplicable switches.
