SureFit Flexible Earhook
The Profile SureFit headset comes out of the box with the SureFit flexible
earhook installed (see Figure 2). The earhook is worn on the ear and can be
reshaped for a comfortable and secure fit.
SureFit Flexible EarhookWearing
Use your fingers to grasp and reshape the gray area of the earhook. Black areas
cannot be reshaped. The earhook retains its shape until reformed.
To put on your new SureFit earhook (see Figure 3):
1. Straighten out the earhook so that it points away from the speaker.
2. Swing the hook away from the speaker and slide the SureFit earhook
behind your ear until the saddle of the hook rests on the uppermost part
of your ear.
3. Adjust the flexible hook with your thumb until it rests comfortably along
the back of the ear.
4. Lightly press the speaker against the ear for proper positioning.
To remove, simply lift the Profile SureFit off your ear. The SureFit earhook
retains its custom contouring for the next time you put it on. Just slip it into
place and gently snug up the flexible portion of the hook.
Refer to the Microphone Positioning section for additional information.

Earloop
The Profile SureFit headset can be fitted with a choice of earloop sizes. An
earloop completely encircles the ear and positions the speaker directly over
the ear canal. Four earloops are supplied, each marked as follows: X (Extra
Small), S (Small), M (Medium) and L (Large). The size mark appears near
the thinnest portion of the earloop. The earloop connects to the receiver
using a T-hinge (see Figure 7).
Installation
1. Remove the earhook or headband.
2. Select the desired earloop size.
3. Snap the T-hinge onto the center portion of the earloop.
4. Hold the receiver firmly in one hand and press the stub end of the
T-hinge with the other hand into the mounting post on the receiver until
it snaps into place.
5. Pivot the earloop so that it encircles the receiver.
Removal
1. Rotate the boom 90° (see Figure 8).
2. Pivot the earloop away from the receiver and rotate the earloop so it is
perpendicular to the receiver body.
3. Firmly grasp the earloop by placing your fingers through the ring.
4. While grasping the receiver housing, pull apart until the T-hinge pops
free of the mounting post.

Changing Ears
To accommodate left or right ear wearing styles, rotate the microphone boom
over the headband (see Figure 12). Do not force the microphone boom
beyond the built in stops!
HeadbandWearing
Position the headset lightly on your head (see Figure 13). The Stay-Put™
click-stop headband lengthens and shortens to the desired length for a custom
fit (pull to lengthen, push to shorten). The headband retains its length and will
not need adjusting each time it is put on. The stabilizer cushion rests just
above the ear on the side of your head opposite the speaker.
Refer to the Microphone Positioning section for additional information.

Microphone Positioning
For all Profile SureFit headsets, the microphone boom should be adjusted so
that the microphone is approximately one half inch (12 mm) below and away
from your lower lip (see Figure 14). The 405-FLEX-SF and Profile Mobile are
equipped with a noise-canceling microphone, and the 405-UNC-SF is
equipped with an ultra-noise-canceling microphone. These directional
microphones reject background noise and are better suited for noisy
environments. Proper microphone positioning is necessary to take advantage of
the noise-canceling qualities of these microphones.
Depending upon the model purchased, your Profile SureFit headset has either
a fixed or a flexible microphone boom:
Flex boom models (405-FLEX-SF and Profile Mobile) have a flexible boom
that can be reshaped until the microphone is correctly positioned in front of
your mouth. One hand should grasp and steady the receiver end of the boom.
The other hand can then flex the boom (see Figure 15).
Fixed boom models (405-SF and 405-UNC-SF) have a telescoping
microphone boom that can be adjusted by pulling the boom in or out of the
receiver assembly. The fixed boom also pivots (at the receiver) away from or
toward your mouth (see Figure 16). Do not bend a fixed boom!
CAUTION: Never forcefully rotate the microphone boom past its stop point in
the receiver assembly!
Clothing Clip
The clothing clip should be fastened for comfortable wearing (see Figure 17).
It is designed to prevent the weight of the cord from dislodging the headset.
Position the clip conveniently on your clothing. To reduce excess slack,
reposition the clip by sliding it up and down the cord.
