3.5 Speaker
The Intellicom comes with a 35 Ω speaker that is controlled through the Dynamic C func-
tion
call. The maximum average volume was measured to be 75 dBA @ 30 cm (12 inches) from
the speaker. Figure 13 shows typical volume measurements for various frequencies with the
speaker grille open and closed to maintain water resistance for the front mounting panel.

3.6 Vacuum Fluorescent Display
A vacuum fluorescent display (VFD) may be
substituted for the LCD by removing R22 and
substituting a VFD for LCD. Note that a VFD
has no backlighting and no contrast control.
The instructions for accessing the display are
similar to those for accessing the keypad insert
in Appendix B, “Keypad and Plastic Enclosure.”
