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.
