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 first time. To charge the battery, slide it gently into
the provided 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 finger 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 film 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 compartment.
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
compartment.
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 blocking 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 AUTOMATICALLY
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. GTechnology 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 off.

TO ADJUST THE DETECTION RANGE
1. Move your finger 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:
• If the detection range is set to 6 feet, pressing the button
changes the range from 6 feet to 9 feet. You hear 3 beeps.
• If the detection range is set to 9 feet, pressing the button
changes the range from 9 feet to 3 feet. You hear 1 beep.
• If the detection range is set to 3 feet, pressing the button
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
microfiber cloth. Clean the frames by wiping them with a damp cloth.
Clean the sonar sensor with a microfiber 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 off and on again to reset the
sonar sensor. Contact G-Technology Group for technical support.
