1. THE INDEPENDENT
Independent is a small and lightweight device which is equipped with an ultrasonic
and laser sensor. It can be attached to clothes with its clip or with the enclosed
magnet holder. In this way, the device detects obstacles in the area of the head and
the upper body. Information is given via acoustic signals. It is recommended to
always use the enclosed lanyard so that you cannot lose the Independent.
Scope of supply:
Independent device, micro USB cable with power plug adaptor, lanyard, small pouch,
magnet holder, two holders (11 and 14 mm diameter to attach the device to a cane)
user manual in black-print and an USB flash drive including the manual.
How to turn on the device:
By pressing and holding both operating buttons, you can turn on Independent. The
power on sequence is signalled with a Start-Up sound. If the distance is not changing
(remains constant) 30 min the device switches off automatically after 30 minutes of
inactivity in order to save energy. In case there is an obstacle in the surroundings, the
30-minutes countdown starts from the beginning until the switch-off. The power off
sequence is signalled with a Switch-Off Signal. By pressing and holding both
operating buttons, you can turn off the Independent manually.
If the measured distance is constant for 5 seconds, the device is going into Stand-By
mode, which is signaled with the Stand-By sound. As soon as the distance to
obstacles has changed by 0,3 m, the Independent is reactivated and it outputs
corresponding signals. The device goes also intostandby mode when the userstands
in front of obstacles without moving (forexample if the user stands still facing a person
while talking with that person).
In the default setting, the volume level is set to level 3 and the ultrasonic and laser
sensors are active.

Place the Independent in front of you so that the front side of the device (with its
operating buttons) is on the top and the USB port is pointed to the left.
FRONT SIDE REVERSE SIDE
Front side
On the front side of the device, you will find two operating buttons with tactile
markings. The upper right button is button 1, which is marked with one tactile
point. The upper left button is button 2, which is marked with two tactile points.
At the lower side below the operating buttons, you can feel centrally located a
small hole, which is the speaker. Below directly under the speaker, there is also
centred the laser sensor. Below the laser sensor, you can feel two round
covers: this is the ultrasonic sensor.
Reverse side
On the reverse side of the device, you will find a clip, which is respectively grooved
on the top and bottom. (3 horizontal lines on the top and 2 horizontal lines on the
bottom). In the top corner on the left, behind the clip, there is a small palpable hole
of about one millimetre deep –this is the Reset button.

1.1. BUTTON COMBINATION
To operate Independent different key combinations and either a short or a long press
of one or two buttons are used.
Buttons 1+2
- Short button press: to adjust gradually the volume level
- Long button press: to switch on the device; you will hear the “Start-up sound”
To switch off the device keep the buttons 1+2 long pressed. You will hear the
“Switch-off sound”.
Button 1
- Short button press: sets the range
- Long button press: activates the wireless connection
Button 2
- Short button press: informs the user which sensor mode is active; a second
short press within the next 5 seconds changes the operation mode
- Long button press: checks the battery level
1.2. ACOUSTIC SIGNAL –VOLUME LEVEL
Independent offers three volume levels. The default setting is level 3; it is the
highest volume level.
To change the volume, press the buttons 1+2 briefly.
Starting from the default setting level 3, the device goes through all the 3 levels:
A single, short press of both buttons sets the volume to level 1 (very low).
Output:
1 short signal = volume level 1
2 short signals = volume level 2
3 short signals = volume level 3

6
1.3. RANGE
You have the possibility of setting on the Independent the range up to 1 or up to
2 m. The default setting is up to 2 m.
To change the range, press the button 1 briefly.
Output:
1 short signal = range up to 1 m
2 short signals = range up to 2 m
1.4. SENSOR MEASUREMENT
By using the Independent, you can select between three sensor modes. The active
measurement can be ultrasonic- or laser sensor only, or both sensors combined. The
factory setting is the combination of ultrasonic and laser sensor.
To change the sensor measurement, press the button briefly.
A first press informs you about the actual mode that is operating.
A second short press within the next 5 seconds changes the sensor mode.
The mode setting is stored, which means that the device will use the same selected
settings after it has been powered off and turned on again the next time.
Please note that if the battery is completely discharged, the user settings (sensor
mode, distance range and audio volume) will be reset to the factory values.
Output:
1 short signal = the ultrasonic sensor is active
2 short signals = the laser sensor is active
3 short signals = the ultrasonic- and laser sensors are active
Notice:
The laser sensor is in laser class 1. The laser is completely safe and not
dangerous for the user!
Extract from the brochure „Information about laser safety“(AUVA):
Safe laser devices. These are either safe because their output is very low, or
because in normal operation they have a protecting casing which shields the laser radiation
outward.
The laser products in laser class 1 are not dangerous for the users.

1.5. CHARGING THE BATTERY –CHECKING THE BATTERY LEVEL
To charge the battery, connect the device via Micro-USB cable with a power socket.
Alternatively, you can recharge your battery by connecting it to your PC. By doing so,
you will hear the signal sequence „Battery Charging Started“. At the end of this
operation, you will hear the signal sequence „Battery Charging Completed“. When the
battery is fully discharged, the recharging process can take up to 2 hours.
To check the load status, press and hold button 2.
Battery status:
1 short signal = battery almost empty
2 short signals = battery half full
3 short signals = battery fully charged
To find out if Independent is already fully loaded, press and hold button 2 during the
charging process. If the battery is still being recharged, you will get the „Battery
Charging Started“-signal sequence. If the battery has been fully charged, you will get
the „Battery Charging Completed“-signal sequence.
Notice:
To prolong the life span of the USB connection and USB port, we
recommend good maintenance. Plug in the USB connector
properly, thus ensuring that the USB plug fits correctly into the
port. If the battery is completely discharged, the user settings
(sensor mode ultrasonic and lidar, distance range and audio
volume) will be reset to the factory values.
2. TROUBLESHOOTING
If the device does not function properly, connect your device to the included USB
charger for at least one hour. Try switching on the device as usual.
Resetting the device to the factory settings
If Independent, despite fully charged battery, does not output any signal in case of
obstacles or it does not react to button presses, it is advisable to reset the device to
its factory settings. Take a suitable pointed object (e.g. a paper clip or wire).
Insert the wire into the small (1 mm) Reset hole in the top left corner on the reverse
side of the device and press briefly. If you hear the start-up sound, your device is
ready for operation again. If this reset procedure does not function, the device must
be repaired. Therefore, please contact the manufacturer.
