Using the following procedure, verify that the four following channnels inputs are recording
correctly, regardless of Audio Control Panel mode or audio (communications radio) selection:
Channel 1: Cockpit Spare Audio Input (3rd Crew Member, Public Address System)

a.
Connect the PI to the FA2100 CVR’s GSE connector as shown in Figure 6.
b.
Using the PI’s SELECT button, activate the Monitor Menu and turn HQ VOICE
CH 1 ON. While someone is speaking into the Channel 1 source, verify that the audio is clear
and distortion-free. Monitor the audio with the PI’s internal speaker or with a 600-ohm head-
set connected to the PI’s phone jack (an 8–ohm headset must be used for the 2100–1020–93
configuration).
c.
Repeat this process for CH 2, CH 3, and HQ CAM CH 4.
d.
If the GMT input has been connected to the recorder, confirm proper operation by using the
real time GMT display function of the PI. This is found under the Special Functions menu.
GMT is supplied to the recorder as a low speed ARINC 429 input using Label 125 or Label
150. GMT can also be supplied as FSK audio mixed with channel 1 or 3 with the
2100–1020–02 recorder.
NOTE:
The PI does not display ARINC 429 GMT or rotor speed in the Monitor Mode. This can
only be done with the PI in the Playback Mode.

The Bulk Erase function can occur only when the aircraft is resting on its landing gear. After
pressing and holding the Control Unit’s bulk ERASE push button for a minimum of 2 se-
conds, release it and verify Bulk Erase function by listening for a 400-Hz tone at the HEAD-
SET jack. Tone duration is approximately 4 seconds.

OPERATIONAL TESTS
5.1
Preflight Functional Check
The Preflight Functional Check assures the operator of FA2100 CVR System integrity. Therefore, it
must be performed before every flight or whenever maintenance has been performed on the aircraft which
may have affected the performance of the FA2100 CVR System.
Press and hold the Cockpit Control Unit’s TEST push button for a minimum of five seconds.
For installations containing Model S151/S161, Model S152/S162, or Model S251/S261 Control Units,
the panel-mounted TEST lamp illuminates when the FA2100 CVR has passed the testing. (The TEST
lamp stays on as long as the TEST button is pressed.)
For installations containing Model A151B or Model A152B Control Units, the meter is used as a
‘GO-NO-GO’ indicating device. The meter needle rises to and remains within, the ‘GO’ (green) section
of the meter scale when the FA2100 CVR has passed the testing. (The meter needle stays in the ‘GO’
section of the meter scale as long as the TEST button is pressed.)
