CAUTIONS
Here are some general tips to follow for safe use of this product:
•Always turn the volume down before plugging the earphones into a
sound source.
•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 are connecting these earphones to an airplane's sound system,
please use the level attenuator provided with the E5c earphones, and
make sure that the level attenuator volume is all the way down. This pre-
vents loud messages by the pilot from causing hearing discomfort.
•Shure recommends that you have your ears checked by an audiologist
on a regular basis. If you experience wax buildup in your ears, stop us-
ing the earphones until an audiologist has examined your ears.
•Wipe the earphones with an antiseptic before and after use to avoid in-
fections. Stop using the earphones if they are causing great discomfort
or infection.

EARPHONE COMPONENTS
1) Earphones. The earphone with the BLUE marking fits in the left ear,
while the earphone with the RED marking fits in the right ear. When
properly inserted, the Shure logo will appear right-side up on the outside
of the earphone with the cable exit pointing forward and upward.
2) Sleeves. The earphones come with a pair of foam sleeves (installed),
and a trial assortment of flex sleeves -small, medium, and large.
3) Adjustment Tube. For a secure fit, slide the adjustment tube back and
forth to adjust the slack of the cables leading to the earphones.
4) In-line Crossover. Optimally blends the frequencies of the two drivers.
5) Input Connector. 3.5 mm (1/8-inch) plug connects to the 3.5 mm ste-
reo earphone output of a listening device.

INSERTING THE EARPHONES
1. Insert the earphones using the following guidelines:
•Note the difference between the right and left earphones:
earphone with blue dot = left ear
earphone with red dot = right ear
•When inserting the earphones, pull the ear upward and outward to
straighten out the ear canal.
2. Wrap the form-fitted wire over the top and down the back of the ear.
3. Use the adjustment tube to secure the cables comfortably.
•Flex sleeves -Try the different sizes to
determine the best fit for comfort and
isolation.
•Foam sleeves -Compress the foam sleeve
at the end of the earphone by rolling it be-
tween your thumb and forefinger before in-
serting it. Hold the earphone in place for
about 10 seconds while the foam expands
and creates a tight seal.
•The quality of the frequency
response and sound isolation
depend on how well the sleeves seal.
If the earphone seems to be lacking in low
frequency response, insert the earphone deeper into the ear canal to obtain
a better seal, or try one of the other sleeve options.

LEVEL ATTENUATOR
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.

SLEEVE VARIETIES
CHANGING SLEEVES
The sleeves at the end of the earphones can be replaced by sliding them off
and on. A combination of twisting and pulling is recommended for sleeve
removal.
Flex Sleeves. These reusable sleeves, made of a clear pliable
plastic (PA756) or a soft, gray silicone rubber (PA758), fit com-
fortably in the ear and allow for ease of insertion. Choose from
3 sizes—small, medium or large—for the best fit. These should be
cleaned regularly, using alcohol wipes or an antiseptic.
Foam Sleeves. These disposable foam sleeves compress to
fit in the ear canal. Once in the ear, the foam expands to form
a tight seal that holds the earphones firmly in place.
Triple-Flange Sleeves. These reusable sleeves form a
tighter seal than flex sleeves while holding the earphones
firmly in place. These should be cleaned regularly, using al-
cohol wipes or an antiseptic.
NOTE: On each foam sleeve there is a rough side and a
smooth side. For greater comfort, Shure recommends that you
place the smooth side facing out, away from the earphone.

CARE OF THE EARPHONES
Follow these tips to prevent service costs and ear infections:
•Avoid getting moisture in the nozzle, as this can adversely affect sound
quality. Sweat entering the nozzle may cause the earphone to tempo-
rarily stop working. However, normal operation often returns after the
earphone dries out.
•Avoid striking or dropping the earphones. Extreme shock can damage
them.
•Use the supplied wax removal tool to clean the nozzles after each use
(see figure 1).
FIGURE 1: Wax Removal
•Return earphones to carrying pouch when not in use.
•Foam sleeves should be disposed of and replaced regularly.
