5.3.10 TAWS Audio Check (For Units With TAWS Only)
While on the ground turn the 500 Series unit on in Configuration Mode. The audio panel should also be
turned on for this test.
The TAWS audio volume has an initial default of 60% of the maximum volume value. The TAWS volume
needs to be set so as to ensure that aural alerts are audible under all anticipated noise environmental
conditions.
1. Select the configuration page labeled ‘TAWS AUDIO CONFIG 1’.
2. Go to the
PLAY MSG field. Rotate the small right knob to play the various TAWS audio
messages. There are a total of 24 audio clips. The first audio clip is a 5 second 1 kHz audio tone.
The second audio clip is a "beep-beep" annunciation tone. The remaining 22 audio clips are the
various TAWS system, caution, and warning messages.
3. Select and play a number of the TAWS audio messages. Adjust the volume so the TAWS
messages are audible under all anticipated noise environmental conditions.

small right knob. Turn the knob to the right to increase the volume and to the left to decrease
the volume.
5.3.11 TAWS System Check (For Units With TAWS Only)
While on the ground turn the 500 Series unit on following normal power-up procedures. The audio panel

TAWS unit.

2. Press the MENU key.

Test Terrain? field and press the ENT key.

message.

The aural message “TAWS System Test OK” will be annunciated if the TAWS system is
functioning properly.

The aural message “TAWS System Failure” will be annunciated if the TAWS system is NOT
functioning properly.
