The PA235 provides you with volume control when you are connecting ear-
phones to airplane seat outputs. It is intended only for airline use. It is not in-
tended for use with other audio sources.
To use the PA235:
1. Connect the 1/8-inch jack on the earphones to the female jack on the
PA235.
2. Turn the PA235 volume down completely (toward –).
3. Connect the PA235 to the 1/8-inch audio output of the airplane seat.
4. Insert the earphones into your ears (see Inserting the Earphones)
5. Turn the volume on the PA235 up slightly (toward +).
6. Adjust the seat volume as follows:
•
If the audio is distorted, turn down the volume at the seat.
•
If there is no distortion, but there is background noise, turn up the
seat volume.
7. Adjust the PA235 volume to a comfortable level.
NOTE: the program may be interrupted by messages from the pilot that
are much louder. To avoid discomfort, keep the overall volume just loud
enough for listening enjoyment.
