1 System Description
QUIETPRO is a digital lightweight, intelligent hearing protector and communication terminal for use by noise
exposed personnel. The main components of the system are:
• A control unit with the connectors and push-buttons
• A headset with the required transducers (microphones and loudspeakers)
• High attenuating eartips for sufficient hearing protection
• A radio cable for connection to the appropriate radio system
• An external power supply for battery charging
QUIETPRO is equipped with a user-friendly voice feedback system and indicator lights. Voice messages are given
to guide you through the steps in the menu system and will be used to communicate warnings and alerts.
QUIETPRO is designed to provide the best possible situational awareness and communication while at the same
time protecting the hearing. The unit analyses the surrounding sound and adapts the hearing protector continu-
ously to achieve this. This means that QUIETPRO only attenuates surrounding sound when needed and to the
degree that is needed. The control unit includes volume control buttons, allowing you to reduce or increase the
level of the surrounding sound.
The product uses a range of techniques to protect against noise-induced hearing loss, including high attenuating
eartips, adaptive hear-through, impulse noise protection, and digital Active Noise Reduction (ANR) to increase
attenuation of low frequency noise. QUIETPRO has a built-in fit test that alerts you at start-up if the eartips are not
properly inserted in each earcanal. The system monitors the personal sound exposure based on measurements
from the microphones inside the earpiece. These microphones capture the sound on the inside of the protective
seal, and therefore can be used to calculate the precise personal sound exposure without the need to measure or
estimate the sound attenuation properties of the hearing protection device.
Loudspeaker:
Presents an optimal mix of sound from the surroundings and the
communication system to the ear. It is also used for digital ANR.
Eartip:
High quality protective foam eartip seals off the earcanal from
ambient noise. Two special sound ports/pipes transfer sound
between the transducers and the earcanal.
Inner microphone:
Captures the sound of the human voice present in front of the ear
drum and enables radio communication without an external micro-
phone.
Outer microphone:
Situated on the outside of the hearing protection and captures
sound from the surroundings.

www.honeywellsafety.com/quietpro HONEYWELL SAFETY PRODUCTS
QUIETPRO provides noise protected two-way speech communication when connected to a radio. With the in-
ear headset for high noise scenarios, both voice pick-up and sound regeneration are done in the earcanal, on
the inside of the protective seal. This eliminates the need for a boom microphone in most sound environments,
which make QUIETPRO highly compatible with other personal protective equipment (PPE) including respirators
and masks, firefighter helmets and other head PPE. The control unit includes a push-to-talk (PTT) button for
radio keying, as well as a volume control mechanism for incoming communications.
The radio cables for use with QUIETPRO can be mated with the appropriate connector in the control unit.
All cables have an integrated memory chip with the information needed for the control unit to set up the
appropriate electrical interface to the radio.
The external power supply allows QUIETPRO to charge its built-in battery. Note that this shall not be done in
hazardous areas.

3. Reach around your head and gently pull the ear
to straighten the earcanal.
2. Fit the eartip to the earpiece. Make sure the tip
fully covers the pipes.
2 Getting started
2.1 Charging the battery
Connect the charger to the control unit and fully charge the battery before use. It takes approximately
4 hours to fully charge the battery. For further instructions regarding battery charging, see section 11.
2.2 Connect cables
Connect the cable from the headset to the connector on the control unit marked [HEADSET]. Connect the
radio cable to the communication radio and then to the connector on the control unit marked [COM].
TIP There is a red dot on the connectors to show you how to align the connectors.
! NOTE The radio cable plug has a locking mechanism. To release the connector make sure you take hold
of the locking ring and then pull straight out. By pulling the cable instead of the locking ring, the
cable may be damaged.
! NOTE Depending on your radio(s), there may be connectors with locking mechanisms also in the radio
end of the cable.
2.3 Fitting headset and eartips
A proper fit of eartips ensures good comfort during prolonged use. The eartips are therefore provided in
several different sizes.
TIP Insertion of the eartips and the comfort of the fitting improve with practice. Honeywell recommends
getting help from a QUIETPRO-trained instructor or experienced user to learn how to insert the tips in
the best way.
1. Compress the foam by rolling it into a small
crease-free cylinder.
4. Push the eartip into the earcanal while gently
twisting the earpiece. There is a difference between
the left and the right hand side earpieces.
A marking on the earpiece and cable will show you
which earpiece is made for which ear.

10
www.honeywellsafety.com/quietpro HONEYWELL SAFETY PRODUCTS
5. Keep the eartip in place until the foam has started
to expand and the earpiece stays in place in the
ear, about 5-10 seconds. It may take 20-30
seconds before the foam is fully expanded.
6. The earpiece shall be inserted well into the bowl
of the ear. The earpiece shall not protrude far out
from the earcanal entrance.
7. Fit the cable behind your neck or under your chin.
Use the clip to remove tension from the cable on
the earpieces and secure it to your shirt or jacket.
Make sure the cable is secured in a way so that it
does not get caught up during use.
NO! YES!

HONEYWELL SAFETY PRODUCTS
! CAUTION Some actions or situation can cause noise induced hearing loss. You should ensure that:
• The fit test warning is adhered to by ensuring that he eartips are properly fitted.
• The dose warning is adhered to by seeking out a quieter environment.
• The sound environment does not consist of extreme impulsive noise where the attenuation
provided by the unit is not enough to protect the hearing.
• The eartips are not used as stand alone earplugs.
• The headset is used at all times in noisy surroundings.
If the recommendations above are not adhered to, the protection afforded by the headset will be severely
impaired.
! CAUTION Remove the eartip slowly with a twisting motion to gradually break the seal.
Rapid removal may damage the eardrum.
! CAUTION Before using the QUIETPRO headset ensure your earcanals are sufficiently clean. People with
excessive amounts of ear wax or problems related to the earcanal must consult a doctor
before using the headset. Do not use headset if you are experiencing any medical issues in
your ear or earcanal.
! NOTE Always fit the earpiece with eartips. Tips mounted to the transducer housing will protect the
sound ports/pipes and prevent them from being filled with dirt or water. Dirt or water in the
sound tubes will affect the system performance and may cause permanent damage to the
equipment.
! NOTE The eartips may be adversely affected by certain chemical substances. Further information
should be sought from the manufacturer.
2.4 Starting up the unit
Press [CONFIRM] and hold for 2 seconds to turn ON. When you hear sound in the headset or see the indicator
lights you can let go of the button. At start up, QUIETPRO performs a fit test to make sure the eartips are prop-
erly fitted in each ear. At the same time, it runs a system test that detects possible errors such as a damaged
transducer or blocked sound tubes. The system also analyses the fitting of the eartips and determines which
ear that has the best seal. The microphone in the ear with the best seal will then be used to pick up speech for
radio transmission. During this system test, you will hear a complex sound sequence.
• If the test is successful, the system will enter normal use mode. No particular notification is
given, but you will typically notice that the hear-through is activated such that normal hearing
is restored.
• If the system detects an error, a voice warning will be presented (“poor fit left ear”, “poor fit
right ear”, or “poor fit both ears”) followed by a warning signal. If the fit test failed only for one
ear, the warning signal will be heard in the other. The warning can be acknowledged by double
clicking [CONFIRM]. This will silence the alarm but does not improve the fit. In order to ensure
that your hearing is protected, remove and refit the eartip(s) and restart the system to perform
a new fit test. Refer to section 2.3 for fitting instructions.

3 Menu
QUIETPRO uses a voice feedback menu to handle different settings. The settings selected at the time the
unit is turned off will be stored and activated when the unit is turned on again.
3.1 Navigation
QUIETPRO uses voice feedback together with the two buttons [MENU] and [CONFIRM] to navigate in the
menu. One press on the [MENU] button will enter the menu. The voice feedback will present the first menu
item. Continue to press the [MENU] button to cycle through the top level of the menu and you will hear
the different options being presented to you. To move to a sub-level or to activate a menu item, press the
[CONFIRM] button. Voice feedback will let you know your next option or inform you that the item has been
activated.
If no button is pressed for 3 seconds, the system will exit the menu and return to normal operation. You will
hear a time-out signal as the normal operation is resumed. If you re-enter the menu, you will always start at
the top-most menu item. It is not possible to move backwards in the menu. If you want to go to an earlier
option, either cycle through the menu with the [MENU] button until you hear the option again or wait for time
out and re-enter the menu from the top.
TIP You do not have to wait until the voice message is finished before you move to the next option or
to confirm a choice.
! CAUTION If the fit test fails, the attenuation level cannot be guaranteed, and you are at a greater risk for
hearing damage. To avoid this you have to improve the insertion of the eartip(s) and restart the
system.
! CAUTION If the fit test fails, the digital ANR functionality is disabled. To enable the ANR you have to
improve the insertion of the eartip(s) and restart the system.
TIP If the earpiece is removed from the ear with the unit turned on, feedback from the system may
occur. To avoid this, make sure the unit is turned off before removing or inserting the eartip.
2.5 Shutting down the unit
Press [CONFIRM] and hold for 3 seconds to turn off the unit. You will hear an exit sound as the unit shuts
down. The unit also switches off if the headset is disconnected from the QUIETPRO control unit.

3.3 Menu volume
It is possible to change the volume of the voice feedback. To do this, enter the menu and go to “Advanced
System Setup” – “Menu Volume”. Press [CONFIRM] and then adjust the volume using the Volume [+] and [-]
buttons.
3.4 Menu language
Two alternative languages for the voice feedback are stored in the unit. To change language enter the menu
and go to “Advanced System Setup” – “Menu Language”. Cycle through the language options using the
[MENU] button and press [CONFIRM] to select the language you wish to use.
4 Hear-Through
The system uses the outer microphones to pick up ambient sound. The sound is then analyzed in the unit
and reproduced on the inside of the eartip at a safe level (below 85 dBA). The volume level of the hear-
through is adjustable and weak sounds can be reinforced. During normal operation (i.e. when not operating
the menu) use a short press on the [+] button to increase and [-] button to decrease ambient sound level
step by step. Press and hold the [+] button to go to maximum and [-] button to go to minimum ambient
sound level. A long beep indicates that the maximum or minimum level is reached.
5 Digital Active Noise Reduction (ANR)
QUIETPRO uses digital ANR to improve attenuation. With the ANR activated, the inner microphone captures
the noise signal and from this the electronics generate the appropriate signal through the loudspeaker in
order to emit an inverted sound wave. The result is a reduced noise level. ANR works best in low frequency
noise environments. QUIETPRO will only activate ANR when the noise level is sufficiently high.
The ANR calibration takes place during system start-up and this process adapts the ANR algorithm to your
ear and the way the eartips are inserted. If the fit test fails during start-up, the ANR is disabled. The only way
to achieve a successful ANR calibration is to adjust the fit of the eartips and re-start the system. The user
initiated (through the menu) fit test will not enable ANR. It is possible to disable the ANR function through the
menu. Go to “Advanced System Setup” – “ANR Options” to turn the ANR function on or off.
! CAUTION ANR may generate high sound pressure levels in the ear if calibrated incorrectly. To avoid this,
always switch the unit off before inserting the eartips. If during use, the position of the eartips
changes significantly in the earcanals, the calibration may no longer be valid and the system
needs to be restarted. Refer to section 2.3 for further fitting instructions.
6 Indicator Lights
The indicator lights are there to support the user interface. They are used according to different principles
depending on their purpose:
• Green/yellow/red as in low/medium/high for noise dose (see section 10)
or high/medium/low for battery status (see section 11.1).
• Green pulsing to signal that a user action succeeded.
• Yellow pulsing to signal that an action is running, such as fit test (see sections 2.4 and 8).
• Red pulsing to signal a warning. All warnings are accompanied by an explanatory voice message.
• All three colors will flash as the unit is turned off.

7 Radio Interface
QUIETPRO QP100Ex is only allowed to be used together with intrinsically safe radios with ATEX/IS entity
parameters that are compatible with those of QUIETPRO QP100Ex.
! WARNING Using the system with radios that are not ATEX/IS compliant (even in non-hazardous locations)
will void the ATEX/IS certification of QUIETPRO QP100Ex. Such non-compliance could also
cause serious personal injury to the end user.
The radio cables are equipped with a small memory chip where the parameters, required for the interface
between the radio and QUIETPRO, are stored. When the radio cable is connected to the unit, it triggers the
settings for the correct radio.
7.1 Setting radio volume
To change the radio volume, enter the menu by pressing [MENU]. The radio volume will be your first option.
Press the [+] button to increase and [-] to decrease the radio volume step by step. Because this action will be
performed quite often it is handled differently than other menu items. You do not need to push [CONFIRM] to
activate the function but can start adjusting the volume directly. The voice feedback will announce the volume
level and also let you know when maximum or minimum level is reached. After the radio volume is set and no
button is pushed for 3 seconds, the system will exit radio volume mode with a time-out signal. The volume
buttons will now operate the hear-through volume again.
TIP Adjust the volume control on the radio to approximately 80%. Use the volume buttons on the
QUIETPRO control unit to increase and decrease the volume further.
TIP Setting the volume on both the radio and the QUIETPRO unit too high may cause sound
distortion. Always use the lowest possible volume setting that gives sufficient speech intelligibility.
7.2 Communication keying mode
There are two different modes for keying the communication radio; Push-to-Talk (PTT) and Open Mike. The default
at start-up is PTT mode. To switch between the different modes, enter the menu and go to “Keying Mode”. Cycle
through the options and use [CONFIRM] to select the mode you wish to use. Note that in both cases, the hear-
through function and voice messages will shut down in one ear during transmission to ensure optimal voice pick-up.
Push-to-Talk
To transmit on the radio or intercom system, press and hold the [PTT] button on the side of the control unit.
Release the button to go back to listening mode.
Open microphone
The Open Mike mode is designed for communication systems that allow constant keying, typically intercom
systems. This mode will only be enabled if the connected radio cable identifies itself as being connected to
such a system. It will key the intercom system and keep the voice pick-up microphone constantly open.
Remember that a microphone adds noise to the communication system when kept open.

8 Fit Test
QUIETPRO uses a test to verify that the eartips are fitted properly in each ear and that a minimum acceptable level
of attenuation is achieved. The fit test is automatically run when starting up the unit. It is also possible to initiate
a fit test during use. Enter the menu and go to “Fit Test”. Press [CONFIRM] to start the test. To ensure that the fit
test works optimal, the startup and manual fit test should be run in an environment with low or moderate ambient
noise. The user should also avoid speaking during the startup and manual fit test.
TIP Hot-key for fit testing – double click [CONFIRM] during normal use.
If the test is successful, the system will return to normal use mode. No particular notification is given, but you
will typically notice that the hear-through is activated such that normal hearing is restored.
If the system detects an error, a voice warning will be presented (“poor fit left ear”, “poor fit right ear”, or “poor
fit both ears”) followed by a warning signal. If the fit test failed only for one ear, the warning signal will be heard
in the other. The warning can be acknowledged by double clicking [CONFIRM]. This will silence the alarm but
does not improve the fit. In order to ensure your hearing is protected, remove and refit the eartip(s) and restart
the system to perform a new fit test. Refer to section 2.3 for fitting instructions. ANR is disabled if the fit test fails.
! CAUTION If the fit test fails, the attenuation level cannot be guaranteed, and the user is at a greater risk
for hearing damage. To avoid this you have to improve the insertion of the eartip(s) and re-run
the fit test.
! CAUTION A user initiated fit test does not enable ANR functionality. The unit needs to be restarted and a
successful start-up sequence performed to enable ANR.
7.3 Earmuff Mode
The voice pick-up for outgoing radio communication is automatically adjusted depending on the surrounding noise
environment. If you are wearing earmuffs, this feature may not work as intended as the noise level at the outer micro-
phone is attenuated by the earmuff. To improve voice pick-up in this scenario, enter the menu and select “Advanced
System Setup” – “Earmuff Mode Options” and choose “Earmuff Mode On”. The setting will be kept even if you
restart the control unit. You must enter the menu and choose “Earmuff Mode Off” if you work without earmuffs and
want to benefit from automatically noise adjusted outgoing radio communication.
TIP When using earmuffs on top of a QUIETPRO headset, the outgoing communication
quality can be improved by setting the hear-through level to minimum.

10 Dose Measurements
QUIETPRO is equipped with means of measuring the sound energy reaching your ear – your noise dose.
100% dose corresponds to the permissible exposure level, i.e., the maximum sound energy that is considered
as a safe exposure in one full work shift1. During normal operation the unit will communicate the dose that
you have been exposed to using the LED indicators.
Green light flashing slowly Less than 50%
Yellow light flashing slowly 50 to 80%
Yellow light flashing quickly 80 to 95%
Red light flashing quickly More than 95%
When the 95% mark is reached, a voice message will warn you that the dose will exceed the permissible
exposure level. This warning is followed by a wobble tone. You can turn the warning signal off by pressing
[CONFIRM] twice. This will only silence the warning. In order to protect the hearing it is important that you find
work in a quiet area for the remainder of the work shift.
Turning the unit off will not reset the dose to zero. In order to deal with situations where QUIETPRO is switched
on/off several times during a work shift, the unit calculates dose in a sliding time window. This means that at
any time, the exposure is defined to be the cumulative exposure during the latest 16 hour period. If you want to
override this functionality, it is possible to implement a procedure where you reset the dose to zero at the start
of every work shift. To do so, enter and cycle the menu using [MENU] until you hear “Dose Options” then press
[CONFIRM]. Select “Dose Reset” and “Confirm Dose Reset” using [CONFIRM].
It is possible to request the dose status. To do so, enter and cycle the menu using [MENU] until you hear “Dose
Options” then press [CONFIRM]. Select “Get Dose Status” in this new menu level using [CONFIRM]. The noise
dose status will be reported using the indicator lights and voice feedback.
1) The permissible exposure level varies between different countries and different organisations.
It is defined through system configuration.

11 Battery/Charging
QUIETPRO is powered by a lithium-ion rechargeable battery.
11.1 Battery status
The typical battery capacity for continuous use is 40 hours. Battery capacity depends on a range of factors
such as usage pattern, noise environment, battery condition and temperature. The system allows you to check
the remaining capacity of the batteries. To do so, enter the menu and go to “Get Battery Status”, then press
[CONFIRM]. It is also possible to request the battery status using the hot-key access.
TIP Hot-key for battery status: Press and hold [MENU] and [CONFIRM] for 3 seconds.
The battery status is presented by voice messages and indicator lights. The values below are valid for typical
conditions and lower battery capacities can be expected for older/used batteries. Note that for temperatures
below -20°C / -4°F, the battery capacity will be significantly lower than what is stated here.
Green steady light / “Battery level full” Typically more than 24 hours left
Yellow steady light / “Battery level medium” Typically more than 12 hours left
Red steady light / “Battery level low” Typically more than 1 hour left
Red blinking light / “Battery level very low” Unit should be charged
11.2 Low Battery Warning
The system will automatically give you a low battery warning when there is approximately 1 hour left of the
expected battery life. The warning will be repeated every 10 minutes. When the low battery warning is
announced, the unit should be charged immediately.
11.3 Automatic shutdown
To avoid full battery discharge, the system will shut down after 4 hours of inactivity (no button pressed).
A warning message will be given 10 minutes before shut down. To avoid automatic shutdown in this case,
press any button. Automatic shutdown can be disabled through the menu system under “Advanced System
Setup” - “Automatic Shutdown Options”.
11.4 Charging the battery
Connect the charger to the control unit as showed in the illustration below. It takes approximately 4 hours to
charge a completely discharged battery. A yellow indicator light will be lit during charging and this will change
to green when the battery is fully charged. The unit should be turned off before connecting the charger.

12.1 External Microphone
Depending on which version of headset you are using, it may be equipped with a connector for external micro-
phone. When the connector for the external microphone is plugged in, the external microphone will be used
for voice pick-up. No settings in the menu needs to be changed. When the external microphone connector is
disconnected, the unit will automatically enable the in-ear microphones to be used for voice pick-up.
When using the Open Mike keying mode, the unit will not detect connection or disconnection of the external
microphone. If you wish to change microphone for the voice pick-up, first set keying mode to PTT, connect
or disconnect the external microphone and then set keying mode to Open Mike again.
