•
The CQA apk can be used to verify a broken audio path. Under the “Audio” menu, select
“Mic Loopback”.
–
The “PRIMARY MIC” setting allows a mic1 to earpiece loopback
(recommended
)
•
Note* - The “DEFAULT MIC” setting also allows this, if a headset device is not plugged in.
–
The “SECONDARY MIC” setting loops mic2 to the earpiece, and so on and so forth; *Note* there
are
5
microphones
on this device.
–
If a headset is inserted, the “DEFAULT MIC” setting will loopback the headset mic if one exists
rather than the handset primary mic.
–
Selecting the other microphone paths while a headset is inserted will loopback the audio to the
headset speakers/output device.
•
If no mic-to-earpiece loopback paths are not functional, the earpiece speaker path is likely
damaged. In the “AUDIO” menu of the CQA apk, select “Ear Speaker” and the “Buzz
Sweep” should begin playing. Toggle and select “Play Harvard speech pattern” to hear
human speech to be sure the transducer is operating correctly.
•
The loudspeaker can be tested by selecting “Loudspeaker” via the CQA apk. A musical
composition should start playing and be easily heard.
•
If audio is not present on the HEADSET path, select the “Headset” entry in the main menu
of the CQA app, then plug-in the headset device to view whether the lack of audio is a
detection-cycling issue or other anomaly.
