PA235 LEVEL ATTENUATOR
The PA235 provides you with volume control when you are connecting
earphones to airplane seat outputs. It is intended only for airline use. It is not
intended for use with other audio sources.
To use the PA235:
Connect the 1/8-inch jack on the earphones to the female jack on the
PA235.
Turn the PA235 volume down completely (toward – ).
Connect the PA235 to the 1/8-inch audio output of the airplane seat.
Insert the earphones into your ears (see Inserting the Earphones)
Turn the volume on the PA235 up slightly (toward +).
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.
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.

SAFE USE
Use a slow twisting motion to remove the earphones. Never pull
on the earphone cord.
Warning: If a sleeve becomes lodged in your ear, seek skilled
medical assistance to remove the sleeve. Damage to the ear
may be caused by non-professionals attempting to remove the
sleeve.
Prior to inserting the earphone, always recheck the sleeve to
make sure it is firmly attached to the nozzle.
Turn up the volume control only far enough to hear properly.
Ringing in the ears may indicate that the volume level is too high.
Try lowering the volume.
If you connect these earphones to an airplane’s sound system,
listen at low levels so that loud messages from the pilot do not
cause discomfort.
Have your ears checked by an audiologist on a regular basis. If
you experience wax buildup, discontinue use until an audiologist
has examined your ears.
Stop using the earphones if they are causing great discomfort or
infection.
