OVERVIEW
The Sensear SM1 and SM1x models hearing defense systems are state-of-the-art hearing protectors.
The systems have sophisticated electronics and algorithms to enhance speech in noisy
environments. As a result, Sensear SM1 and SM1x users do not need to remove their hearing
protection to hear speech in noisy environments.
In addition, the SM1x units incorporate Bluetooth technology, external audio pass-through and twoway radio connectivity. This enables users to effectively answer a phone call, listen to an MP3
player or use a two-way radio whilst wearing their hearing protection.
The SM1 unit is functionally identical to the SM1x in every respect, with the exception of the
Bluetooth connectivity function. The SM1 communication features include face-to-face and twoway radio connectivity.
The SM1 Ultra and SM1x Ultra models include a noise cancelling boom microphone for extreme
noise environments. Standard models may be upgraded by purchasing the boom microphone
upgrade kit.
The SM1 and SM1x are available in over-the-head headband or helmet mount models. Helmet
mount adaptors are available for a wide range of helmets. The SM1 and SM1x were tested with
Protector HC600 safety helmets and may give different levels of protection if fitted to different
helmets.
The basis of the SM1 and SM1x units consists of advanced signal processing algorithms that
process sound. The output of these algorithms is referred to as the SENS processed sound. In the
SENS processed sound, the speech of nearby speakers is enhanced while at the same time, the
surrounding noise is suppressed. The SENS processed sound is the sound delivered to the SM1
and SM1x users.
WARNING: The reported attenuation will be obtained only if the SM1/SM1x is in good condition and
worn as directed (Refer to AS/NZS 1269.3 for guidance).
Noise reduction will be adversely affected by anything that impairs the seal of the earmuff
cushions against the head, such as thick spectacle frames, balaclavas, etc. Cushions may
deteriorate with use and should be renewed regularly.
4
GETTING STARTED
To fully utilise the functionality provided by the Sensear SM1 and SM1x models, please ensure
that the Sensear SM1 and SM1x are worn correctly. See the inside front cover for illustrations of
fitting the SM1/SM1x.
It is recommended that the SM1/SM1x are fitted, adjusted and maintained in accordance with
Sensear’s instructions; the ear-muffs are worn at all times in noisy surroundings and the cushions
are regularly inspected for serviceability. If these recommendations are not adhered to, the
protection afforded by the ear muffs will be severely impaired.

BLUETOOTH
Configuring the SM1x to be a Bluetooth headset for a cell phone is a two-step process.
Firstly, the SM1x must be paired with the cell phone. Secondly, the SM1x must be connected to
the cell phone. Pairing is required only once. When completed, each time the SM1x is powered up,
the SM1x automatically connects to the cell phone it was last paired with.
Pairing and Connecting with a Cell Phone
Pairing represents the exchange of a security key to enable secure communications between the
SM1x and the cell phone. To complete pairing, the following steps should be followed:
Step 1. Enter “Pairing Mode”, which makes the Bluetooth module on SM1x
discoverable:
• Press and hold the “Multi-Function” button for five seconds. The Blue LED will illuminate solid
blue and an audible message will be played. The user can now use a cell phone to find the
Sensear SM1x and commence the pairing process.
Step 2. Find the SM1x on a cell phone:
• Ensure that Bluetooth is enabled on the cell phone. Perform a search for Bluetooth devices on
the cell phone and select Sensear SM1x from the list of discovered devices.
Step 3. Enter the PIN (Passkey) on the cell phone:
• The PIN (Passkey) is “0000” (zeros). The pairing will then be completed. Note at this point, some
cell phones will automatically connect to the SM1x. If so, Step 4 is not required.
Following pairing, the Sensear SM1x will be stored in the list of paired devices on your cell phone.
Similarly, your cell phone is stored in the memory of the SM1x.
Step 4. Connect the SM1x to the cell phone:
• Press and hold down the “Volume Down” button for one second. An audible message will play,
notifying the user that the SM1x is attempting to connect to the cell phone. When connection
is completed successfully, the SM1x plays the message “Connection Completed” and the Blue
LED flashes at the normal rate. On some cell phones the user may have to “authorise” the
SM1x to complete the connection.
IMPORTANT NOTES:
The SM1x stores pairing information for only ONE cell phone at a time. Each cell phone
paired over-writes the previously paired phone in the memory of the SM1x. Any cell phone
that is not registered in the memory of the SM1x, regardless if it has previously been
paired, will require pairing with the SM1x again.
If pairing is not completed within two minutes after entering “Pairing Mode”, the system
will leave “Pairing Mode” and notify the user with a message.
NOTE: The SM1x can only enter the “Pairing Mode” if the two-way radio interface is NOT
operational. Ensure that the two-way radio is unplugged before attempting to enter the
“Pairing Mode”. Alternatively, leave the two-way radio plugged into the system, ensuring
that the radio is turned off.

Using Bluetooth Functions
The user must first have connected the SM1x to the cell phone to use Bluetooth functions on the
SM1x.
The functions are described below:
Accepting an incoming call
• When the phone is ringing, press and release the “Multi-Function” button. Note that when the
phone is ringing, a ring tone will also be delivered by the SM1x. In addition, the Blue LED will
flash at the faster rate.
• After accepting the call, a brief “Call Accepted” sound will be heard and the Blue LED will
continue to flash at the faster rate.
Rejecting an incoming call
• When the cell phone is ringing, press and hold the “Multi-Function” button for one second.
A “Call Rejected” sound will be heard and the Blue LED will return to flash at the normal rate.
If “Call Divert” is enabled on the cell phone, the caller will be directed to voicemail.
Ending an active call
• When the user is on a phone call, press and hold the “Multi-Function” button for one second.
A “Call Ended” sound will be heard and the Blue LED will return to flash at the normal rate.
Adjusting the Bluetooth phone call volume
• While the user is on a phone call, press and release the “Volume Up” button.
• While the user is on a phone call, press and release the “Volume Down” button.
Disconnecting the cell phone from SM1x
• Using the cell phone, navigate through the “Active Bluetooth Devices” menu, select the SM1x
and select “Disconnect”. The Blue LED will turn off.

TWO-WAY RADIO INTERFACE
Connecting a two-way radio unit to the SM1/SM1x requires a 2-way radio audio adapter cable
available from your Sensear stockist. Several adaptors are available to suit a wide range of
Motorola, ICOM and Kenwood radios. Insert the six pin connector into the 2-way radio interface
socket on the SM1/SM1x. Attach the audio adapter to the two-way radio unit. Contact your nearest
Sensear distributor to obtain the required adapters for two-way radios.
The SM1/SM1x will deliver the incoming two-way radio transmission. Note that the incoming twoway audio is mixed with the SENS processed sound.
To speak over the two-way radio, use the following function:
Push-To-Talk (PTT)
• Press and hold the “Multi-Function button”, which has the same effect as pressing the “PTT”
button on the two-way radio. Speak normally and the user’s voice will be sent through the
Sensear system to the two-way radio.
IMPORTANT NOTES:
Always use the “Multi-Function” button and not the “PTT” button on the two-way radio,
to activate the PTT.
The volume of the two-way radio played back cannot be changed using the SM1/SM1x
volume controls. The volume is controlled only by the two-way radio unit.
PTT functionality is disabled if there is an incoming Bluetooth phone call, or if the user
is currently on a phone call via Bluetooth.
The two-way radio interface can be enabled/disabled as described in “SYSTEM SET-UP”.
If the interface is enabled, the user will be able to use the SM1/SM1x as a two-way radio
accessory to communicate on two-way channels. Note that the factory setting for the twoway radio interface is “Enabled”.

BOOM MICROPHONE POSITIONING AND USE
The SM1 Ultra and SM1x Ultra are fitted with flexible boom microphones that allow 2-way radio and
mobile phone call operation in extreme noise situations. The standard SM1 and SM1x may be
upgraded by purchasing a the Ultra Boom Microphone Upgrade – see ACCESSORIES AND
SPARE PARTS. The upgrade kit contains an Allan key, M5 nut and boom clamp.
Remove the rubber microphone attachment cover and attach the boom microphone and clamp as
shown in Figure 3. Lightly tighten M5 screw so that the boom position can just be adjusted by hand.
Place the ear-muffs on the head and adjust the boom position until the end of the microphone is
adjacent to the corner of the mouth. Remove the ear-muffs and tighten the M5 screw using the
Allan key provided, Insert the 2.5mm audio connector into the audio jack.
For optimum use, the boom microphone should be positioned within 5mm of the mouth.

TWO-WAY RADIO VOX OPERATION
The SM1 and SM1x support Voice Operated Switch (VOX) functionality, allowing hands free
operation of 2-way radios. Note that this option is only available if a boom microphone is attached.
By default the VOX setting is disabled. Follow the steps in SYSTEM SET-UP to enable the VOX.
Once enabled, the VOX function detects speech through the boom microphone and automatically
activates the radio transmitter.
VOX operation is not recommended in windy conditions.
EXTERNAL AUDIO PASS-THROUGH
If the external audio pass-through has been enabled, (Factory setting is “Disabled” - see important
notes following), the SM1/SM1x can be used as a stereo headset to listen to audio from external
devices. External devices that can be used include iPods, other portable MP3 players, PC’s,
laptops, portable CD/cassette players, FM/AM radios and any other device with “line-out” audio
output.
Connecting an external audio device to the SM1/SM1x requires an optional audio cable, available
from your Sensear stockist. Insert the threaded 3.5mm end of the cable into the Audio socket on
the SM1/SM1x. Insert the other 3.5mm end of the audio cable into the external audio device.
Note that the audio coming from external devices is mixed together with the SENS processed
sound and delivered to the user. External audio pass-through can also be permanently disabled.
To complete this, take the following steps:
Step 1
• When the SM1/SM1x is turned off, while pressing and holding down the “Multi-Function” button
and the “Volume Down” button, press and release the "Power" button.
Step 2

TROUBLE-SHOOTING
If the Sensear SM1 or SM1x is not functioning correctly, first refer to this Section for simple
trouble-shooting. This can save time and effort, however if symptoms persist, consult your
nearest Sensear Service Centre.
The SM1/SM1x does not power up.
Ensure that the battery is sufficiently charged. Charge the battery according to the instructions
given in the Section, “CHARGING”.
Bluetooth is not working.
Ensure that the Bluetooth is enabled in the System Set-up.
Two-way radio interface is not working.
Ensure that the two-way radio interface is enabled in the System Set-up.
External audio pass-through is not working.
Ensure that the external audio pass-through has not been permanently disabled and that it is
enabled in the System Set-up.
Volume of the two-way radio is too loud or too quiet.
Adjust the volume on your two-way radio.
The volume of the two-way radio cannot be adjusted using the volume controls on the SM1/SM1x.
Volume of the external audio device is too loud or too quiet.
Adjust the volume on your external audio device.
The volume of your external audio device cannot be adjusted using the volume controls on the
SM1/SM1x.
Unable to enter “Pairing Mode” (i.e., unable to make the Bluetooth module on the SM1x
discoverable).
The SM1x can only enter the “Pairing Mode” if the two-way radio interface is not in use. Ensure the
two-way radio is unplugged before attempting to enter the “Pairing Mode”. Alternatively, leave the
radio plugged into the system, however ensure that the radio is turned off.
The SM1x does not connect, either automatically or manually, to the cell phone it was
last paired with.
Ensure that the cell phone is ready to accept Bluetooth connections. This means that Bluetooth is
enabled on the cell phone and the phone is not connected to other Bluetooth devices.
Please note that on some phones, the user may also need to “authorise” the SM1x to connect to
the phone.
The SM1x does not connect, either automatically or manually, to a previously paired
cell phone after another cell phone has paired with the SM1x.
The SM1x stores pairing information for only one cell phone at a time. If another cell phone has
paired with the system since last paired with it, the user will need to pair with the system again.

The SM1x connects, either automatically or manually, to another cell phone.
The SM1x contains pairing information for the other cell phone. Press and hold the “Multi-Function”
button for five seconds to enter “Pairing Mode”.
This will clear the current pairing memory, which will ensure that the SM1x does not connect to
another cell phone.
The SM1x does not re-connect to the cell phone when powered on immediately after it
was powered off while connected to the cell phone.
If the SM1x is powered off while connected to the cell phone, it can take up to 20 seconds for the
phone to become ready to accept a new Bluetooth connection.
If the SM1x is powered back up during these 20 seconds, the automatic connection at the powerup will fail. To prevent this, ensure that 20 seconds lapse between powering off and back up.
If the automatic connection fails, the user can still connect manually to the cell phone once the
phone becomes ready to accept a new Bluetooth connection.
Bluetooth connection is lost after an incoming call is accepted using the cell phone’s
“Answer” button.
When an incoming call is accepted using the cell phone’s “Answer” button, a small proportion of cell
phones automatically close the connection to their Bluetooth headset, (in this case, the SM1x) and
re-route the audio to the phone’s speakers. They do this on the assumption that by answering the
call using the phone, the user wishes to use the phone’s microphone and speaker and not those on
the Bluetooth headset. To prevent this from happening, always use the “Multi-Function” button on
the SM1x to accept incoming calls.
