Vox Operation And Privacy Mode; External Audio Pass-Through - Sensear SM1 Manual Del Usuario

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".
