OVERVIEW

The Sensear SM1, SM1x and SM1x SR 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, SM1x and SM1x SR users do not need to remove their hearing protection to hear speech in noisy environments.

In addition, the SM1x SR units incorporate FM short range connectivity, Bluetooth technology, external audio pass-through and two-way radio connectivity. This enables users to communicate to other SM1x SR users wirelessly, effectively answer a phone call, listen to an MP3 player or use a two-way radio whilst wearing their hearing protection.

The SM1x unit is functionally identical to the SM1x SR in every respect, with the exception of the FM short range connectivity. The SM1x communication features include Bluetooth technology, external audio pass-through, face-to-face and two-way radio connectivity.

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 (SR) 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, SM1x and SM1x SR are available in over-the-head headband or helmet mount models. Helmet mount adaptors are available for a wide range of helmets. See section Helmet Mounts.

The basis of the SM1, SM1x and SM1x SR 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, SM1x and SM1x SR users.

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.

GETTING STARTED

To fully utilise the functionality provided by the Sensear SM1, SM1x and SM1x SR models, please ensure that the Sensear SM1, SM1x and SM1x SR are worn correctly. See Figure 1 for an illustration of ﬁ tting the SM1/SM1x(SR).

It is recommended that the SM1/SM1x(SR) are ﬁ tted, 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 chemical impaired.

The basic functions of getting started with the Sensear SM1, SM1x and SM1x SR are described below.

IMPORTANT NOTE: The SM1/SM1x(SR) cannot be powered down while charging is taking place. While the user is in the “System Set-up”, or on a telephone call, the volume of SENS processed sound cannot be changed.

Please refer to the Sections, “BLUETOOTH” and “SYSTEM SET-UP” for more information.

BLUETOOTH

Conﬁ guring the SM1x(SR) to be a Bluetooth headset for a cell phone is a two-step process. Firstly, the SM1x(SR) must be paired with the cell phone. Secondly, the SM1x(SR) must be connected

to the cell phone. Pairing is required only once. When completed, each time the SM1x(SR) is powered up, the SM1x(SR) 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(SR) 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(SR) discoverable:

• Press and hold the “Multi-Function” button for ﬁ ve seconds. The Blue LED will illuminate solid blue

and an audible message will be played. The user can now use a cell phone to ﬁ nd the Sensear SM1x(SR) and commence the pairing process.

Step 2. Find the SM1x(SR) 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(SR) 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(SR). If so, Step 4 is not required.

Following pairing, the Sensear SM1x(SR) 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(SR).

Step 4. Connect the SM1x(SR) 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(SR) is attempting to connect to the cell phone. When connection is completed successfully, the SM1x(SR) plays the message “Connection Completed” and the Blue LED ﬂ ashes at the normal rate. On some cell phones the user may have to “authorise” the SM1x(SR) to complete the connection.

IMPORTANT NOTES: The SM1x(SR) 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(SR). Any cell phone that is not registered in the memory of the SM1x(SR), regardless if it has previously been paired, will require pairing with the SM1x(SR) 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(SR) 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.

NOTE: The SM1x SR can only enter the “Pairing Mode” if Short Range Communication is NOT operational. Short Range Communication may be enabled in the User Menu, but must be ‘OFF’ (simultaneous press on “Volume-Up” and “Volume-Down”) before attempting to enter “Pairing Mode”.

Using Bluetooth Functions

The user must ﬁ rst have connected the SM1x(SR) to the cell phone to use Bluetooth functions on the SM1x(SR).

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(SR). In addition, the Blue LED will ﬂ ash at the faster rate.

• After accepting the call, a brief “Call Accepted” sound will be heard and the Blue LED will continue

to ﬂ ash 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 ﬂ ash 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 ﬂ ash 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(SR)

• Using the cell phone, navigate through the “Active Bluetooth Devices” menu, select the SM1x

and select “Disconnect”. The Blue LED will turn off.

SHORT RANGE FM COMMUNICATIONS (SM1XSR MODEL)

The SM1xSR provides short range, half duplex, wireless communications with a range of up to 50 meters.

Before Short Range Communication can begin, Short Range FM must be enabled in the System Setup. Navigate through the menu to Communication Option and Enable Short Range FM.

After it has been “Enabled”, SHORT RANGE COMMUNICATIONS MUST BE TURNED ON. Turn ON Short Range FM by simultaneously pressing “Volume up” and “Volume down”. The user will then receive a message advising that Short Range FM has been turned on.

Frequency The Short Range Communication Frequency can be selected in the System Setup. The default frequency is 101.3MHz (Region1), 107.9 MHz (Region 2) or 97.0 MHz (Region 3).

All SM1xSR units must be setup on the same frequency if they are to communicate with each other.

NOTE: A Frequency must be found that is entirely free from interference (eg radio stations) to ensure best performance.

Region The Short Range Communication Region can be selected in the system Setup. The region selection determines the appropriate RF Power Level settings for the SM1x SR required to satisfy regulatory requirements.

Region 1 Australia and New Zealand Region 2 Western Europe (CE Countries) Region 3 USA and Canada (FCC Countries)

WARNING: Selecting the incorrect regional setting may violate regulatory requirements. The default regional setting will be set to the region where the product was purchased.

Volume To adjust the Short Range FM volume the SM1x SR should ﬁ rst be placed in QUIET Mode. Press and release the “Power” button until QUIET Mode is selected. Press the “Volume Up” or “Volume Down” buttons to adjust the Short Range FM volume.

Note that SENS volume can only be adjusted when the SM1x SR is in SENS Mode.

FM Radio Operation

SM1xSR units with FM hardware allows the user to tune into broadcast FM in the 88-108MHz frequency range.

Prior to operation, the FM Radio option must ﬁ rst be enabled in the System Settings. Once this has been done, FM Radio can be turned on or off by simultaneously pressing the “Multifunction” and “Power” buttons.

Adjusting FM Radio Volume To adjust the FM Radio volume the SM1x SR should ﬁ rst be placed in QUIET Mode. Press and release the “Power” button until QUIET Mode is selected. Press the “Volume Up” or “Volume Down” buttons to adjust the FM Radio volume.

Note that SENS volume can only be adjusted when the SM1x SR is in SENS Mode.

Selecting FM Radio Stations The FM radio is set to a default station of 94.5 MHz. To select a different station the SM1x SR must ﬁ rst be placed in QUIET mode. Press and release the “Power” button until QUIET mode is selected.

PRESS AND HOLD THE “VOLUME UP” BUTTON TO SCAN UP IN FREQUENCY TO THE NEXT FM RADIO STATION. PRESS AND HOLD THE “VOLUME DOWN” BUTTON TO SCAN DOWN IN FREQUENCY TO THE PREVIOUS FM RADIO STATION.

TWO-WAY RADIO AND WIRED COMMUNICATION INTERFACE

The 6 pin connector at the bottom of the right earcup is used for connecting to two-way radios, mobile phones and other wired communications devices.

Two-way Radio Before a two-way radio can be used on this interface “two-way radio” must be “enabled” in “communications options” in the system setup. See section on system set-up.

Connecting a two-way radio unit to the SM1/SM1x(SR) 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(SR). 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(SR) will deliver the incoming two-way radio transmission. Note that the incoming two-way 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(SR)

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(SR) as a two-way radio accessory to communicate on two-way channels. Note that the factory setting for the communications options is “Two-Way radio Enabled” for the SM1 and SM1x models and “Short RangeFM Enabled” for the SM1xSR models.

WIRED COMMUNICATIONS

Before a device other than a two-way radio can be used on this interface “wired communications” must be “enabled” in “communications options” in the system setup. See section on system set-up. For compatible cables to use with devices see your Sensear stockist.

Note: Wired communication can be turned on and off by pressing the “multifunction button”. In this mode, the SM1/SM1x(SR) will deliver the incoming audio to the wearer’s ears. Note that the

incoming audio is mixed with the SENS processed sound. The wearer’s speech is continuously transmitted over the cable.

Different devices that could interface to this connector may require different audio levels. Use the “Wired Communications Levels” in the System Setup to adjust the outgoing audio volume.

BOOM MICROPHONE POSITIONING AND USE

The SM1 Ultra and SM1x(SR) Ultra are ﬁ tted with ﬂ exible boom microphones that allow 2-way radio and mobile phone call operation in extreme noise situations. The standard SM1, SM1x and SM1xSR may be upgraded by purchasing 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.

VOX OPERATION AND PRIVACY MODE

The SM1, SM1x and SM1x SR support Voice Operated Switch (VOX) functionality, allowing hands free operation of 2-way radios and Short Range FM (SM1xSR model). 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.

If VOX has been enabled then speech may trigger the VOX, transmitting to all listeners on the same frequency. In some situations this may not be desirable, if for example the speaker wishes to have a private conversation with someone nearby.

In this situation the SM1/SM1x(SR) can be placed in “PRIVACY Mode”. PRIVACY Mode inhibits transmission of the user’s speech over the Short Range FM communication channel.

By pressing and releasing the “Power” button the SM1/SM1x(SR) will cycle between, SENS, PRIVACY and QUIET modes. Note that the PRIVACY Mode option is only available when VOX is enabled.

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(SR) 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(SR) requires an optional audio cable, available from your Sensear stockist. Insert the 3.5mm end of the cable into the Audio socket on the SM1/ SM1x(SR). 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(SR) 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

• Press and release the “Volume Up” button to conﬁ rm.

• The user will then receive a message advising that external audio pass-through has

been permanently disabled. The SM1/SM1x(SR) will then shut down automatically. When powered up again, all functions relating to external audio pass-through, including System Set-up options, will have disappeared.

IMPORTANT NOTES: Once permanently disabled, the external audio pass-through cannot be restored. The volume of external audio cannot be changed using the SM1/SM1x(SR) volume controls.

The volume must be controlled on the user’s external audio device. External audio pass-through can be temporarily enabled/disabled, as described in “SYSTEM

SET-UP”. Note that the factory setting of the external audio pass-through is “Disabled”.

TROUBLE-SHOOTING

If the Sensear SM1, SM1x or SM1x(SR) is not functioning correctly, ﬁ rst 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(SR) does not power up.

Ensure that the battery is sufﬁ ciently 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(SR) discoverable).

The SM1x(SR) 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(SR) 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(SR) to connect to the phone.

The SM1x(SR) does not connect, either automatically or manually, to a previously paired cell phone after another cell phone has paired with the SM1x(SR).

The SM1x(SR) 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(SR) connects, either automatically or manually, to another cell phone.

The SM1x(SR) contains pairing information for the other cell phone. Press and hold the “MultiFunction” button for ﬁ ve seconds to enter “Pairing Mode”.

This will clear the current pairing memory, which will ensure that the SM1x(SR) does not connect to another cell phone.

The SM1x(SR) 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(SR) 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(SR) is powered back up during these 20 seconds, the automatic connection at the power-up 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(SR)) 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(SR) to accept incoming calls.

Short Range FM does not work.

Ensure ﬁ rstly that “Communications Options” in the System Setup has been set to “Short Range FM Enabled”. Secondly Short Range FM has to be turned ON by simultaneously pressing “Volume Up” and “Volume Down”.

Short Range FM is turned ON but will not transmit or receive.

If two SM1xSR units are to communicate, they must be tuned to the same frequency. See section on Short Range FM Communications Frequency.

If all SM1xSR units are tuned to the same frequency but still do not communicate, try changing the frequency on all SM1xSR units to ensure that there is no FM Broadcast Radio station on the operating frequency.

VOX Does not work properly.

VOX is designed to operate in environments with up to 105dBA of noise. The trigger level of the VOX has been set at the factory to ensure that it does not trigger in these noise levels. In order for your voice to trigger the VOX –

Move the boom close to your mouth and ﬁ nd a position where it picks up the greatest 1. amount of your voice.

Speak Firmly.2.

There is a short processing delay after you start to speak before VOX enables the transmitter. Continuous speech is required to ensure that the transmitter remains enabled.

OVERSIGT

Sensear SM1, SM1x og SM1x SR høreværn modeller er de allernyeste indenfor beskyttelse af hørelsen. Systemerne har avancerede elektronikker og algoritmer der forbedrer tale i støjende omgivelser. Det betyder at med Sensear SM1, SM1x og SM1x SR kan brugerne beholde deres høreværn på når de skal høre tale i støjende omgivelser.

Derudover tilbyder SM1x SR indbygget FM kort rækkevidde radio, Bluetooth teknologi, ekstern lydgennemgang og to-vejs radio kommunikation. Dette sætter brugerne i stand til at kunne kommunikere trådløst med andre SM1x SR brugere, besvare en telefonopringning, lytte til en MP3 afspiller eller bruge en to-vejs radio mens de har høreværnet på.

SM1x apparatet har præcist de samme funktioner som SM1x SR med undtagelse af FM kort rækkevidde radioen. SM1x kommunikationsfunktionerne omfatter Bluetooth teknologi, ekstern lydgennemgang, direkte ansigt til ansigt og to-vejs radio kommunikation.

SM1 apparatet har præcist de samme funktioner som SM1x med undtagelse af Bluetooth tilslutningsfunktionen. SM1 kommunikationsfunktioner omfatter ansigt til ansigt og to-vejs radio kommunikation.

SM1 Ultra og SM1x (SR) Ultra modellerne har desuden en støjreducerende mikrofon på en mikrofonarm til meget støjende omgivelser. Standardmodellerne kan opgraderes ved at købe en mikrofon på mikrofonarm som ekstratilbehør.

SM1, SM1x og SM1x SR modellerne er tilgængelige som hovedtelefon eller til påmontering på en hjelm. Tilpasningsstykker til hjelme ﬁ ndes til en lang række forskellige hjelme. Se afsnittet hjelm beslag.

Grundlaget for SM1, SM1x og SM1x SR apparaterne består af avancerede signal bearbejdnings algoritmer som behandler lyd. Effekten af disse algoritmer omtales som SENS bearbejdet lyd. SENS bearbejdet lyd forstærker tale fra personer i nærheden samtidigt med at støj fra omgivelserne bliver undertrykt. SENS bearbejdet lyd er lyden der leveres til brugerne af SM1, SM1x og SM1x SR.

Støjreduceringen vil blive betydeligt forringet af alt der forhindrer hovedtelefonerne i at sidde tæt mod hovedet som f.eks et kraftigt brillestel, en balaklavahue osv. Puderne på hovedtelefonerne bliver slidte og bør jævnligt udskiftes.

KOM GODT I GANG

For at kunne gøre brug af funktionerne der er tilgængelige sammen med SM1, SM1x og SM1x SR modellerne skal du sørge for at Sensear SM1, SM1x og SM1x SR sidder rigtigt. På ﬁ gur 1 kan man se en tegning der illustrerer hvordan SM1/SM1x(SR) skal sidde.

Det anbefales at SM1/SM1x(SR) bliver justeret, tilpasset og vedligeholdt i overensstemmelse med Sensears vejledninger og at hovedtelefonerne altid bliver anvendt i støjende omgivelser samt at puderne bliver kontrolleret regelmæssigt. Hvis disse anbefalinger ikke bliver efterlevet vil beskyttelsen som hovedtelefonerne yder blive forringet.

De basale trin til at komme godt i gang med Sensear SM1, SM1x og SM1x SR er beskrevet nedendor.

• Tryk på “Sænk lydstyrke” knappen og giv slip for at sænke lydstyrken.

BEMÆRK: SM1/SM1x(SR) modellerne har en indbygget begrænsende lydstyrke funktion, der sikrer at den maksimale støjeksponering bliver begrænset ifølge EN352-4. I meget støjende omgivelser, bliver lydstyrken automatisk nedsat for at sikre at støjeksponeringen ikke overstiger et sikkert niveau. Se venligst afsnittet “Niveau kriterier” for yderligere

oplysninger.

Advarsel. Effekten af det niveauafhængige kredsløb i dette høreværn kan overstige det udefrakommende lydniveau.

Dæmpning af den SENS bearbejdede lyd

• Tryk på “Tænd” knappen og giv slip for at få adgang til “Stille tilstand”.

• Brugeren vil stadigvæk kunne bruge den to-vejs radio kommunikation og besvare telefonopkald

men vil ikke høre den SENS bearbejdede lyd.

• Når apparatet beﬁ nder sig i ”Stille tilstand” vil den grønne LED indikator blinke hurtigere. Se venligst afsnittet ”LED INDIKATORER” hvis du ønsker yderligere oplysninger.

Genopret den SENS bearbejdede lyd

• Tryk på “Tænd” knappen og giv slip igen.

• Når man forlader ”Stille tilstand” vil den grønne LED indikator blinke med normal hastighed igen.

VIGTIG BEMÆRKNING: SM1/SM1x(SR) apparatet kan ikke slukkes mens det bliver opladet. Mens brugeren beﬁ nder sig i “System indstillinger” eller under en telefonsamtale, kan lydstyrken af den SENS bearbejdede lyd ikke ændres.

Se venligst afsnittene ”Bluetooth” og ”System indstillinger” for yderligere oplysninger.

BLUETOOTH

Konﬁ gurationen af SM1x(SR) til brug sammen med en mobiltelefon er en to-trins process. Først skal SM1x(SR) sammenkobles med mobiltelefonen. Dernæst skal SM1x(SR) forbindes med

mobiltelefonen. Sammenkobling skal kun udføres en enkelt gang. Når det er udført, vil SM1x(SR) automatisk blive forbundet med den mobiltelefon den sidst var sammenkoblet med hver gang den tændes.

Sammenkobling og forbindelse med en mobiltelefon

Sammenkobling indbefatter udveksling af en sikkerhedsnøgle der gør sikker kommunikation mellem SM1x(SR) og mobiltelefonen mulig. For at udføre sammenkoblingen skal følgende trin følges:

1. trin. Aktiver “Sammenkoblings tilstand” hvilken gør Bluetooth modulet på SM1x(SR)

synligt:

• Tryk på “Multi funktion” knappen og hold den nede i fem sekunder. Den blå LED indikator vil lyse

klar blå og en hørbar meddelelse vil blive afspillet. Brugeren kan derefter bruge en mobiltelefon til at søge efter Sensear SM1x(SR) og påbegynde sammenkoblingsprocessen.

2. trin. Søg efter SM1x(SR) på en mobiltelefon:

• Sørg for at Bluetooth er aktiveret på mobiltelefonen. Udfør en søgning efter Bluetooth apparater på mobiltelefonen og vælg Sensear SM1x(SR) fra listen over fundne apparater.

3. trin. Indtast PIN koden på mobiltelefonen:

• PIN koden er “0000” (ﬁ re nuller). Sammenkoblingen vil blive udført. Her bør det bemærkes, at visse mobiltelefoner vil automatisk blive forbundet til SM1x(SR). Hvis dette er tilfældet kan 4. trin springes over.

Efter sammenkoblingen vil Sensear SM1x(SR) blive gemt på listen over sammenkoblede apparater i din mobiltelefon. Din mobiltelefon bliver ligeledes gemt i hukommelsen på SM1x(SR).

4. trin. Forbind SM1x(SR) til mobiltelefonen:

• Tryk og hold “Sænk lydstyrke” knappen nede i et sekund. Der afspilles en hørbar meddelelse som informerer brugeren om, at SM1x(SR) forsøger at forbinde til mobiltelefonen. Når forbindelsen er succesfuldt udført, afspiller SM1x(SR) meddelelsen “Forbindelse udført” og den blå LED indikator blinker ved normal hastighed. På nogle mobiltelefoner skal brugeren først autorisere SM1x(SR) for at kunne udføre forbindelsen.

VIGTIGE BEMÆRKNINGER: SM1x(SR) gemmer kun sammenkoblingsoplysninger for én mobiltelefon ad gangen.

Hver mobiltelefon der sammenkobles overskriver den forrige sammenkoblede telefon i hukommelsen på SM1x(SR). Enhver mobiltelefon der ikke er registreret i hukommelsen på SM1x(SR), uanset om den tidligere har været sammenkoblet, vil kræve at den bliver sammenkoblet med SM1x(SR) igen.

Hvis sammenkoblingen ikke ﬁ nder sted indenfor to minutter efter “Sammenkoblings tilstand” åbnes, vil systemet forlade ”Sammenkoblings tilstand” og informere brugeren med en meddelelse.

BEMÆRK: SM1x(SR) kan kun åbne “Sammenkoblings tilstand” hvis det to-vejs radio kommunikations interface IKKE er i brug. Sørg for at den to-vejs radio kommunikation er afbrudt inden du begynder at åben ”Sammenkoblings tilstand”. Du kan evt. lade den to-vejs radio kommunikation være forbundet men du skal sørge for at radioen er slukket.

Brug af Bluetooth funktioner

Brugeren skal først have forbundet SM1x(SR) apparatet til mobiltelefonen for at anvende Bluetooth funktionerne på SM1x(SR).

Funktionerne beskrives nedenfor:

Besvar et opkald

• Når telefonen ringer skal du trykke på “Multi funktion” knappen. Bemærk at når telefonen ringer, vil

der samtidigt lyde en ringetone fra SM1x(SR) apparatet. Og derudover vil den blå LED indikator blinke med en højrere hastighed.

• Efter du har besvaret opringningen, vil en kortvarig ”Opkald besvaret” lyd kunne høres og den

blå LED indikator vil fortsætte med at blinke med høj hastighed.

Afvis et opkald

• Når telefonen ringer skal du trykke på “Multi funktion” knappen og holde denne nede i et sekund.

En “Opkald afvist” lyd høres og den blå LED indikator vil begynde at blinke med normal hastighed. Hvis ”Viderestilling” er aktiveret på mobiltelefonen, vil vedkommende der har ringet op blive viderestillet til telefonsvarer.

Afslut en samtale

• Når brugeren taler i telefon, skal du trykke på “Multi funktion” knappen og holde denne nede i et sekund.

En “Opkald afsluttet” lyd høres og den blå LED indikator vil begynde at blinke med normal hastighed.

Justering af Bluetooth lydstyrken

• Under telefonsamtalen tryk på “Forhøj lydstyrke” knappen og giv slip.

• Under telefonsamtalen tryk på “Sænk lydstyrke” knappen og giv slip.

Afbryd mobiltelefonen fra SM1x(SR) apparatet

• Ved hjælp af mobiltelefonen navigeres gennem “Aktiv Bluetooth apparater” menuen og “Afbryd”

SM1x(SR) vælges. Den blå LED indikator vil slukke.

KORT RÆKKEVIDDE FM KOMMUNIKATIONER (SM1XSR MODEL)

SM1xSR apparatet tilbyder kort rækkevidde, halv-dupleks, trådløse kommunikationer med en rækkevidde på op til 50 m.

Inden kort rækkevidde kommunikation kan begynde, skal kort rækkevidde FM aktiveres i system indstillinger. Gå gennem menuen til Kommunikation valgmuligheder og Aktiver kort rækkevidde

FM.

Efter den er blevet “Aktiveret”, skal KORT RÆKKEVIDDE KOMMUNIKATIONER TÆNDES. TÆND for kort rækkevidde FM ved at trykke på “Forhøj lydstyrke” og ”Sænk lydstyrke” samtidigt. Brugeren vil derefter modtage en meddelelse at kort rækkevidde FM er blevet tændt.

Frekvens Kort rækkevidde kommunikationsfrekvensen kan vælges i system indstillinger. Standardfrekvensen er 101,3MHz (Region 1), 107,9 MHz (Region 2) eller 97,0 MHz (Region 3). Alle SM1xSR apparater skal indstilles på den samme frekvens hvis de skal kunne kommunikere med hinanden.

BEMÆRK: Man skal ﬁ nde en frekvens helt uden forstyrrelser (f.eks fra radiostationer) for at sikre det bedste resultat.

Region Kort rækkevidde kommunikationsfrekvense regionen kan vælges i system indstillinger. Valget af region er afgørende for den passende RF strømniveau indstilling til SM1xSR der kræves for at overholde gældende regler.

Region 1 Australien og New Zealand Region 2 Vesteuropa (Central europæiske lande) Region 3 USA og Canada (FCC lande)

ADVARSEL: Valg af den forkerte regionale indstilling kan være et brud på gældende regler. Standard regionindstillingen vil være den samme som hvor apparatet er blevet fremstillet.

Lydstyrke For at tilpasse kort rækkevidde FM lydstyrken bør SM1xSR apparatet først anvendes i STILLE tilstand. Tryk på “Tænd” knappen indtil STILLE tilstand fremkommer og giv slip. Tryk på “Forhøj lydstyrke” eller “Sænk lydstyrke” knapperne for at justere kort rækkevidde FM lydstyrken.

Bemærk at SENS lydstyrken kun kan justeres når SM1xSR beﬁ nder sig i SENS tilstand.

FM radio anvendelse

SM1xSR apparater med FM hardware sætter brugeren i stand til at lytte til udsendelser på FM

88-108 MHz båndet. Inden anvendelse skal FM radioen først aktiveres i system indstillinger. Når det er sket, kan FM

radioen blive tændt og slukket ved at trykke ”Multi funktion” og ”Tænd” knapperne ned samtidigt. Justering af FM radio lydstyrken For at tilpasse FM radio lydstyrken bør SM1xSR apparatet først

indstilles i STILLE tilstand. Tryk på “Tænd” knappen indtil STILLE tilstand fremkommer og giv slip. Tryk på “Forhøj lydstyrke” eller “Sænk lydstyrke” knapperne for at justere FM radio lydstyrken.

Bemærk at SENS lydstyrken kun kan justeres når SM1xSR beﬁ nder sig i SENS tilstand. Valg af FM radiostationer FM radioen er indstillet som standard på en station på 94,5 MHz. For

at vælge en anden station skal SM1xSR først indstilles i STILLE tilstand. Tryk på “Tænd” knappen indtil STILLE tilstand fremkommer og giv slip.

TRYK PÅ “FORHØJ LYDSTYRKE” KNAPPEN FOR AT SCANNE FREKVENSERNE OPAD TIL DEN NÆSTE RADIOSTATION. TRYK PÅ “SÆNK LYDSTYRKE” KNAPPEN FOR AT SCANNE FREKVENSERNE NEDAD TIL DEN FORRIGE RADIOSTATION.

TO-VEJS RADIO OG KABELFORBUNDEN KOMMUNIKATIONSINTERFACE

Den seks-benede stikforbindelse i bunden af den højre hovedtelefon bruges til at tilslutte to-vejs radioer, mobiltelefoner og andet kabelforbundet kommunikationsudstyr.

To-vejs radio

Inden en to-vejs radio kan bruges på dette interface, skal to-vejs radio kommunikation ”aktiveres” under kommunikations valgmuligheder i system indstillinger. Se afsnittet om system indstilling.

For at tilslutte en to-vejs radio enhed til SM1x(SR) kræves der et to-vejs radio lydadapter kabel som kan købes hos Sensear. Der ﬁ ndes adskillige forskellige tilgængelige kabler der passer til de ﬂ este Motorola, Icom og Kenwood radioer. Isæt den seks-benede stikforbindelse i to-vejs radio interface kontakten på SM1/SM1x(SR) apparatet. Forbind radioadapteren til den to-vejs radioenhed. Henvend dig hos din nærmeste Sensear forhandler for at anskaffe de nødvendige adaptere til tovejs radio kommunikation.

SM1/SM1x(SR) leverer den indkommende to-vejs radio transmission. Bemærk at den indkommende to-vejs lyd er blandet med den SENS bearbejdede lyd.

For at tale henover to-vejs radioen, skal du bruge følgende funktion:

Tryk for at tale (ptt)

• Tryk og hold “Multi funktionsknappen” nede, hvilket har samme virkning, som når du trykker

på ”PTT” knappen på to-vejs radioen. Tal ganske almindeligt og brugerens stemme vil blive transmitteret gennem Sensear systemet til den to-vejs radio.

VIGTIGE BEMÆRKNINGER: Brug altid “Multi funktions” knappen og ikke “PTT” knappen på to-vejs radioen til at aktivere PTT. Lydstyrken i to-vejs radioen kan ikke ændres ved hjælp af SM1/SM1x(SR) lydstyrke

indstillingen. Lydstyrken kan kun justeres med den to-vejs radioenhed. PTT funktionaliteten bliver deaktiveret hvis der kommer et Bluetooth telefonopkald eller hvis

brugeren taler i telefon via Bluetooth. Det to-vejs radio interface kan blive aktiveret/deaktiveret som beskrevet i “SYSTEM

INDSTILLINGER”. Hvis interfacet er aktiveret, vil brugeren kunne bruge SM1/SM1x(SR) som en to-vejs radioenhed til at kommunikere med på to-vejs kanaler. Bemærk at fabriksindstillingen for kommunikations valgmulighederne er ”To-vejs radio aktiveret” for SM1 og SM1x modellerne og ”Kort rækkevidde FM aktiveret” for SM1xSR modellen.

KABELFORBUNDNE KOMMUNIKATIONER

Inden en enhed, bortset fra en to-vejs radio, kan bruges på dette interface, skal kabelforbundet kommunikation ”aktiveres” under kommunikations valgmuligheder i system indstillinger. Se afsnittet under system indstillinger. Hvis du ønsker at se en liste over kompatible kabler der kan bruges med enheder kontakt sensear.

Bemærk: kabelforbundne kommunikationer kan tændes og slukkes ved at trykke på “multifunktions knappen”.

I denne tilstand vil sm1/sm1x(sr) apparatet levere den indkommende lyd til brugerens øre. Bemærk at den indkommende lyd er blandet med den sens bearbejdede lyd. Brugerens tale bliver uophørligt transmitteret via kablet.

Forskellige apparater der passer til denne stikforbindelse kræver muligvis forskellige lydniveauer. Brug ”kabelforbundne kommunikationsniveauer” i system indstillinger til at justere den udgående lydstyrke.

PLACERING AF MIKROFON PÅ MIKROFONARM OG BRUG

SM1 Ultra og SM1x(SR) Ultra er udstyrede med ﬂ eksible mikrofoner på mikrofonarme som tillader to-vejs radio kommunikation og mobiltelefonsamtaler i meget støjende omgivelser. Standard SM1, SM1x og SM1xSR kan opgraderes ved at købe Ultra Boom Microphone Upgrade – se TILBEHØR OG RESERVEDELE. Opgraderingssættet indeholder en skruenøgle, M5 møtrik og en mikrofon spændbøjle.

Fjern gummidækslet til mikrofonen og fastgør mikrofonarmen og spændbøjlen som vist på ﬁ gur 3. Stram M5 møtrikken forsigtigt således at mikrofonarmens placering kan justeres med hånden. Anbring hovedtelefonerne på hovedet og tilpas mikrofonarmen således at mikrofonen beﬁ nder sig lige ud for munden. Fjern hovedtelefonerne og stram M5 møtrikken med den medfølgende skruenøgle. Isæt 2,5 mm lyd stikforbindelsen i jack stikket.

Til optimal ydelse anbefales det at mikrofonen placeres indenfor 5 mm afstand fra munden.

VOX ANVENDELSE OG UFORSTYRRETHEDSTILSTAND

SM1, SM1x og SM1x SR understøtter Voice Operated Switch (VOX) funktionalitet og tillader håndfri betjening af to-vejs radioer og kort rækkevidde FM (SM1xSR model). Bemærk at denne mulighed kun er tilgængelig hvis en mikrofonarm er monteret.

Som standard er VOX indstillingen deaktiveret. Følg trinene i SYSTEM INDSTILLINGER for at aktivere VOX. Når den først er aktiveret, vil VOX funktionen registrere tale gennem mikrofonen og automatisk aktivere radiotransmitteren.

Hvis VOX er blevet aktiveret så kan tale foranledige at VOX transmitteres til alle lyttere på samme frekvens. Dette kan i visse tilfælde vise sig at være uhensigtsmæssigt hvis brugeren f.eks ønsker at føre en privat samtale med en person i nærheden.

I dette tilfælde kan SM1/SM1x(SR) indstilles i “PRIVAT tilstand”. PRIVAT tilstand hindrer transmission af brugerens stemme over kanalen til kort rækkevidde FM kommunikation.

Ved at trykke på “Tænd” knappen og give slip igen, vil SM1/SM1x(SR) skifte mellem SENS, PRIVAT og STILLE tilstande. Bemærk at PRIVAT tilstand muligheden kun er tilgængelig når VOX er aktiveret.

VOX anvendelse kan ikke anbefales i omgivelser med kraftig vind.

UDVENDIG LYD GENNEMGANG

Hvis den eksterne lydgennemgang er blevet aktiveret (fabriksindstillingen er “Deaktiveret” – se efterfølgende vigtige bemærkninger), så kan SM1/SM1x(SR) bruges som stereo hovedtelefoner til at høre musik fra eksterne afspillere. Eksterne afspillere der kan benyttes omfatter iPods og andre bærbare MP3 afspillere, PC’ere, laptops, bærbare CD afspillere, walkman, FM/AM radioer og enhver anden afspiller med en ”line-out” lydudgang.

Hvis du ønsker at tilslutte en ekstern afspiller til SM1/SM1x(SR) apparatet kræves der et ekstra lydkabel som kan købes hos Sensear. Isæt den 3,5 mm lange ende af kablet i lydkontakten på SM1/ SM1x(SR) apparatet. Isæt den modsatte ende af kablet i den eksterne afspiller.

Bemærk at lyden der kommer fra eksterne afspillere bliver blandet med den SENS bearbejdede lyd der sendes til brugeren. Ekstern lydgennemgang kan permanent deaktiveres. For at gøre dette skal du udføre følgende:

1. trin • Mens SM1/SM1x(SR) er slukket, skal du trykke og holde ”Multi funktionsknappen”

nede samtidig med at du trykker på ”Sænk lydstyrke” knappen og trykker og holder ”Tænd” knappen nede.

2. trin

• Tryk på “Forhøj lydstyrke” knappen og giv slip for at bekræfte handlingen.

• Brugeren vil derefter modtage en meddelelse der fortæller, at den eksterne

lydgennemgang er blevet permanent deaktiveret. SM1/SM1x(SR) vil automatisk slukke. Når du tænder for apparatet igen, vil alle funktioner med relation til lydgennemgang inklusive System indstillings valgmuligheder være forsvundet.

VIGTIGE BEMÆRKNINGER: Når du først har permanent deaktiveret den eksterne lydgennemgang kan den ikke

genoprettes. Lydstyrken på eksterne afspillere kan ikke ændres med SM1/SM1x(SR) lydstyrke reguleringen.

Lydstyrken skal justeres på brugerens eksterne afspiller. Ekstern lydgennemgang kan blive aktiveret/deaktiveret som beskrevet i “SYSTEM

INDSTILLINGER”. Bemærk at fabriksindstillingen for den eksterne lydgennemgang er ”Deaktiveret”.
