The Siemens optiPoint 500 telephone is certified with
FCC under Part 68 as a component device for connection
behind FCC Part 68 certified Siemens PBX systems. In
order for the FCC certification of the Siemens optiPoint

not certified, Siemens is required to obtain FCC Part 68

filing to the FCC before that new component can be
used;
• Any modification/update made to the Siemens
optiPoint 500 telephone will require a Part 68
compliance evaluation. Siemens may need to test and
make a modification filing to the FCC before that
modified component can be used;

will continue to comply with all the applicable rules
and regulations in Subpart D of the FCC Part 68 rules

independently or as part of a system), please supply this
manual to the new owner.
