10. Internal microphone connector (3-pin MIC2) (on audio models only)
This connector connects to an optional front panel audio module using
a 3-pin audio cable. If your chassis has this audio module, you can
connect a microphone to the front panel connector .
The front panel microphone may not work properly when there is
another microphone connected to the Microphone (pink) jack on the
rear panel. You may only use one microphone at a time.

11. Chassis alarm lead (4-1 pin CHASSIS)
This lead is for a chassis designed with intrusion detection feature.
This requires an external detection mechanism such as a chassis
intrusion sensor or microswitch. When you remove any chassis
component, the sensor triggers and sends a high-level signal to this
lead to record a chassis intrusion event.
If you do not wish to use the chassis intrusion lead, place a jumper cap
over the pins labeled "Chassis Signal" and "Ground" to close the
circuit.
