on the Desktop Director™. The LED beside this button will light to indicate that
these microphones are muted. Pressing this button again will cancel the muting
function.

These buttons can be used for control of equipment external to the Telos phone
system. For instance the ?#@! button may used to control your obscenity delay
dump, etc.
For details on the output circuitry and pin-outs for these buttons see section 2.9.1.
(user button) – This button controls an output on the parallel control port. This
output will go low for the duration that the button is pressed. This output can control
equipment external to the TWOx12 such as the “delay dump” input on an obscenity
delay unit.

recorder. Pressing this button once cause the Record Start output (pin 3) on the
Parallel Control Port to go true for 1 second. The LED next to this button should now
illuminate.
Pressing the record control button again will cause the Record Stop output (pin 4) on
the Parallel Control Port to go true for 1 second. The LED next to this button should
now go out.
