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.

Headband
The Profile headset can also be equipped with a fully adjustable, lightweight
headband.
Installation

2. Align the mounting post on the receiver over the headband mounting
ring (covered by a foam cushion). The mounting post fits into a notch
on the headband mounting ring (see Figure 10).
3. Place your thumbs over the boom turret.
4. With your fingers behind the headband (on the foam cushion), use your
thumbs to pop the headband onto the receiver.

ring (covered by the foam cushion).
3. With your thumbs on the receiver, push outwardly until the headband
pops free of the receiver.

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.

Connecting toYourTelephone
An amplifier is often needed to connect the headset to the telephone or
telephone system. For these applications, the headset is equipped with a Quick
Disconnect plug which mates to a Quick Disconnect jack on the amplifier.
Follow the instructions supplied with the amplifier to connect the headset and
amplifier to your telephone or telephone system (see Figure 18).
Some telephones do not require amplification. For these applications the
headset is equipped with a cable with a modular plug on the end. The
modular connector plugs directly into a headset port (modular jack) on the
telephone or console. The modular plug cable also has a mated Quick
Disconnect assembly (see Figure 19).
Disconnecting at the Quick Disconnect allows you to move around without
having to remove your headset. If you are on a call, disconnecting at the Quick
Disconnect effectively puts the other party on hold until you return.
For mobile applications, the headset is equipped with a 2.5 mm phono plug
which connects directly into any mobile phone with this size port. For many
mobile telephones without built-in headset ports, adapter kits are available
from your service provider (see Figure 20).
Maintenance
The foam covers on the headband and microphone can be washed in mild
soap and water. Replacement covers are available from your GN Netcom
distributor.

Cautionary Notes to Computer Users
When using any headset with a computer, care should be taken in dry or low humidity environments to protect the user from
electrostatic discharge from the monitor (CRT). Computer monitors can induce a substantial electrostatic charge when turned on or off, or
when there is a power failure, and the resulting electrostatic discharge can be passed through the headset to ground.
A user in close proximity to or touching the computer may feel a common “shock” sensation, similar to touching a doorknob after
walking across a carpet, causing no harm to the user. This discharge is entirely due to the computer monitor; the headset is merely the
shortest path to ground.
To minimize the possibility of electrostatic discharge through the headset, you can:
• Use a grounded screen in front of the monitor.
• Use static dissipative wrist straps.
• Increase the relative humidity in the room to 60% or more.
• Install static dissipative carpets or floor coverings (anti-static sprays can be helpful).
• Remove the headset before turning the computer on or off.
GN Netcom, Inc. Profile headsets meet all OSHA, UL, FCC and CSA standards.
FCC Notice to Users

Part 68 registered device or system. Include the FCC Registration Number and the Ringer Equivalence Number (REN) located on the
amplifier label.
The telco has the right to make changes to their network, which may affect the operation of your equipment, provided you are given
adequate advance written notice to permit correct operation.
