SONAR GLASSES INSTRUCTION MANUAL
INTENDED USE FOR SONAR GLASSES
Sonar Glasses improve mobility independence for blind and visually
impaired people by helping them safely navigate around obstacles in their
path of travel. A subtle vibration in the temple of the glasses alerts the user
to potential hazards that are beyond the reach of a white cane. They are
intended to be used in combination with a white cane or guide dog.
BATTERY
You should make sure that the battery is fully charged before using the
glasses for the rst time. To charge the battery, slide it gently into the pro-
vided battery charger from the rear, and press the battery securely in place.
Make sure the battery contacts, which feel like small holes, are aligned with
the prongs in the charger. On the opposite side of the charger, you will feel a
recessed compartment containing a two-pronged electrical plug. Flip the
electrical plug with your nger so that it is in position to be plugged into an
AC power outlet, then plug the charger into the power outlet. Note: DO NOT
remove the plastic lm that is wrapped around the battery.
It takes about 2 hours to fully charge the battery. The LED on the charger will
be red while the battery is charging, and will turn green when the battery is
fully charged. After it is fully charged, remove the battery and unplug the
charger. The battery operates for approximately 8 – 10 hours per charge.
TO INSERT THE BATTERY INTO THE GLASSES:
1. Locate the battery compartment on the left temple of the glasses and
remove the cover by pulling on the attached lanyard.
2. Slide the battery gently into the battery compartment from the rear, and
press the battery securely in place. Make sure the battery contacts, which
feel like small holes, are aligned with the prongs in the battery compart-
ment.
3. Wrap the battery ribbon around the battery, so that it rests on top of the
battery.
4. Slide the cover into the battery compartment from the rear and press it
securely in place.

TO REMOVE THE BATTERY FROM THE GLASSES:
1. Remove the battery compartment cover, which is located on the left
temple of the glasses, by pulling on the attached lanyard.
2. Pull on the ribbon attached to the battery to pop it out of the compart-
ment.
POWER
The power switch is located on the top edge of the left temple of the glasses.
To turn the power ON, slide the switch forward. Make sure you are not block-
ing the sonar sensor, and wait until you hear the beep tone before using the
glasses. To turn the power OFF, slide the switch back. BE SURE TO TURN OFF
THE POWER WHEN THE GLASSES ARE NOT IN USE, SINCE THEY DO NOT AU-
TOMATICALLY TURN THEMSELVES OFF.
DETECTION OF OBSTACLES
Obstacles in the user's path of travel are detected if they are in the direction
the user is facing, above the waist, below the top of the head, and within
shoulder width. If desired, you can turn your head to the left or right to
detect objects outside your path of travel.
Objects are detected by the sonar sensor, which is located in the center of
the frame between the lenses. A low frequency vibration indicator will be
activated in the right temple of the glasses when an object is detected
within 6 or 9 feet of the user. When a detected object is within 3 feet, the
indicator will vibrate more rapidly. G- Technology Group can customize the
object detection range for the user, if desired.
ADJUSTABLE DETECTION RANGE
Sonar Glasses come with an adjustable detection range. You can adjust the
detection range to 6 feet, 9 feet, or 3 feet. The default detection range for
the glasses is 6 feet. The glasses will default to this setting whenever they
are powered o.

TO ADJUST THE DETECTION RANGE
1. Move your nger along the side of the right temple until you feel a button
in front of the slope in the frame.
2. Press the button and you will you hear beep tones indicating that the
detection range has been changed. The detection range changes from the
default setting of 6 feet in the following sequence:
• Ifthedetectionrangeissetto6feet,pressingthebutton changes the range
from 6 feet to 9 feet. You hear 3 beeps.
• Ifthedetectionrangeissetto9feet,pressingthebutton changes the range
from 9 feet to 3 feet. You hear 1 beep.
• Ifthedetectionrangeissetto3feet,pressingthebutton changes the range
from 3 feet to 6 feet. You hear 2 beeps.
MAINTENANCE
Sonar Glasses do not require scheduled maintenance. DO NOT USE WATER
OR CLEANING SOLUTION TO CLEAN THE LENSES, FRAMES, OR SONAR
SENSOR. Clean the lenses by wiping them with a lint free microber cloth.
Clean the frames by wiping them with a damp cloth. Clean the sonar sensor
with a microber cloth or paper towel.
TROUBLESHOOTING
If the glasses do not power on, insert a fully charged battery and make sure
the sonar sensor is not blocked. Then turn the power ON and wait for the
beep tone. You can test the glasses by placing your hand approximately 12
inches in front of the sonar sensor. You should feel a vibration in the right
temple of the glasses. In case of continuous vibration, turn the power o
and on again to reset the sonar sensor. Contact G-Technology Group for
