Warnings for security
• Do not soak the device
• Do not expose to humidity or steam
• The charger provided with the device is similar to normal domestic charger, therefore it
does not have any lifesaving function and cannot guarantee electric isolation. The following
instructions are thus recommended to avoid any accident:
* Do not use the device while charging
* Do not use the device while connected to the electricity.
* Charge the device only in safe, domestic environments, far from heat sources, water,
steam and other sources of danger.
* Avoid to charge the device in environments that are overly humid, hot or exposed to
the elements.
• Danger of strangulation:
* Do not tighten the charging cable around the neck.
* Keep the charging cable away from children.
• Choking hazard:
* the magnetic charging cable is composed of detachable parts that could be accidentally
swallowed.
The charging cable and the µUSB magnetic adapter should be stored out the reach of
children and animals.

• When the device is in-use, the light source can reach high temperatures: avoid the contact
between the light and the skin and do not touch the LED (located in the middle of the frame).
• When the device is in-use, the part between the temples and the lenses can reach moderately
high temperatures. Avoid the contact between this part and the skin. Whenever an excessive
heat is perceived, turn the device off and get it immediately away from the body and form
people.

Use of the device
Where can you use this device?
This device can be used in everyday life by the visually impaired, wherever it is useful to see
things up close and well-lit, both at home and at work. For example, its use may improve visual
performance in activities such as reading, manipulating objects, and housework.
Using the device does not have contraindications for people who are not visually impaired.
Do not use this device while walking or while driving vehicles.
Use for periods lasting longer than an hour may cause fatigue to the eyes.
Do not look at the light source directly, and do not point it at people, animals,
or approaching vehicles.
Turning the LED light source on and off
The device is equipped with an LED light source designed to generate optimal light and contrast
conditions for near sight. The light source is powered by a couple of rechargeable batteries. If
the LEDs don’t turn on, proceed as indicated in the section entitled “Charging the battery” in this
manual.

13
To turn the light source on, move the switch towards the front of the glasses - the part containing
the lenses.
To turn the light source off, move the switch towards the terminals.
Optimal performance of the device can be reached only with the light source
turned on.
Turning the light source off reduces the performance level of the device, while maintaining
the magnifying power of the lenses.
Operating the device
Remove the Leddles from the case and put them on.
Turn the LED lighting on by moving the on/off switch on the right shaft as described above.
When you wear the Leddles, the optimal distance of the face from the object to be viewed
varies, depending on the lens correction.The optimal range is between 10 cm and 40 cm.
To wear the Leddles in the most comfortable way, you can model the nose pads and the termi-
nals.This adaptation should preferably be carried out by an optician.

14
IftheLEDsash,itmeansthatthebatteriesarealmostat.Rechargethembyfollowingthe
instructions in the section entitled “Charging the battery” in this manual.
Turning the device off
OnceyouhavenishedusingtheLeddles,turntheLEDlightingoffbymovingtheon/offswitch
towards the terminals.
In order to maintain the integrity of your Leddles, device always store it carefully in the provided
case and never leave it unattended.

15
Charging the battery
The device is equipped with a chargeable battery, just like a normal cellular phone.
The following notions will help you to guarantee optimal duration of the batteries, in addition to
adequate charge.

Preliminary operations – Inserting the magnetic adaptor into the
glasses frame
Thefollowingproceduremustbeperformedonlyontherstchargeoperationandintheeventthatthe
magnetic adapter (1) detaches from the glasses.
1) Make sure the magnetic adapter (1) and the magnetic connector (2) are connected as in Fig.1(b)
2) Fully insert the magnetic adapter and the magnetic connector into the glasses, respecting the correct
direction for insertion (wider part of the adapter (1) towards the outside of the temple) Fig. 2 (a).
If you experience excessive resistance during insertion, stop the operation and check whether you have
respected the correct direction of the connector.
3) Disconnect the magnetic connector (2) from the magnetic adapter (1) without pulling it out.
Perform this operation by holding the cable by the body of the magnetic connector (2), slightly bending
the magnetic connector (2) towards the outer or inner part of the frame - Fig. 2 (b).
When the operation is completed, the magnetic adapter (1) must remain incorporated in the
glasses as in Fig. 2 (c).
In case the magnetic adapter too is extracted (1) repeat the preliminary operations from point 1.

Use of the cable with magnetic adapter for charging
the Leddles device
The following procedure must be performed whenever the device needs to be charged.
1) Make sure the magnetic adapter (1) is inserted into the glasses as in Fig. 2 (c). If not, follow the
instructions in the “Preliminary operations - Inserting the magnetic adapter into the glasses
frame” section.
2)Placetheglassesonaatsurface,neartoapoweroutlet,withthetemplesopenandthemagnetic
adapter (1) facing upwards; bring the magnetic connector close to the magnetic adapter - Fig.3 (a) -
untiltheyperfectlyt-Fig.3(b).
If the other end of the cable is not connected to the charger, insert the USB-A connector (3) in the
appropriate slot on the charger. Link the charger to the power outlet. Make sure all the parts are
connected - Fig.3 (c).
3) Make sure that the glasses light source is turned off during the recharging operations.
It takes at least 3 hours for a full recharge of the batteries. If the batteries have been completely
discharged for long time, the full recharge can take over 4 hours.
With fully charged batteries, the LED lighting has an autonomy of about 2 hours and a half.

4) At the end of the charging operations, remove the charger from the power outlet and disconnect
the magnetic connector (2) from the magnetic adapter (1) without pulling it out.
Perform this operation by holding the cable by the body of the magnetic connector (2), slightly bending
the magnetic connector (2) towards the outer or inner part of the frame - Fig. 4 (a) and Fig. 4 (b).
When the operation ends, the magnetic adaptor (1) must remain incorporated in the glasses as in
Fig. 4 (c).
In case the magnetic adapter (1) too is extracted follow the instructions in the “Preliminary
operations - Inserting the magnetic adapter into the glasses frame” section to reposition it
correctly.
