1. Introduction
Congratulations with the purchase of your Looky4! In this manual
you will nd a detailed description of all the functions of the
Looky4. Read this manual carefully before you start using the
Looky4. If you still have any questions after reading this manual,
please contact your supplier.

manual also apply to the Looky4+.

English
3. Intended use
This device is solely used for displaying enlarged representations
of text, photographic material and objects. When the Looky4
is used for any purpose other than the intended use, the CE
regulation will not apply.
Caution: do not, under any circumstances, perform main-
tenance or repairs on the device; always ask a manufacturer
approved technician to do this. Warranty will be voided if
the Looky4 is attempted to be repaired by anyone other
than a technician approved by the manufacturer.
4. Safety and maintenance
Before use, be sure to comply to with the following safety and
maintenance instructions:
• Protect the device and its batteries from moisture, rain, sand
or extreme temperatures like radiators or direct sunlight.
• Do not use cleaning products that contain alcohol, methylated
spirits, ammonia or abrasives. These can damage the device
or its touch screen.
• Only use accessories that the manufacturer supplies you with, or
approves of.
• Never throw batteries into a re. Batteries and chargers that
are defect are considered chemical waste. They therefore need
to be disposed of at a refuse/recycling centre of your choice.
• Note that the use of a screen protector might inuence the
functioning of the touch screen.

5. Installing the battery
Remove the battery lid to place the battery inside the handle of
the Looky4. Replace the battery lid.
Charge the battery completely before using the Looky4.
Please read the charging instructions carefully.
6. Instructions for charging

the adaptor into the wall socket. Connect the narrow end of the
USB cable to the Looky4 to start the charging process.
Note: the dot on the small connector marks the topside.
LED burning constantly batteries are being charged
LED off batteries are fully charged
LED blinking error / batteries are defect
Charge the batteries in a well ventilated environment. Remove
the Looky4 from its carrying case when charging. Don’t place it

7. Battery maintenance
• Remove the battery from the Looky4 if you do not intend
to use it for an extended period of time. This will improve the
longevity of the battery handle.
• Batteries are sensitive to overcharging. It is recommended to
only charge the battery when it is completely drained.
• Chargeable Lithium-Ion batteries have an auto discharge that
strongly depends on the temperature of the environment
(e.g. never leave the battery in a car that is parked in direct
sunlight).
• New Lithium-Ion batteries must be charged several times
before reaching their nominal capacity.
• Charge Lithium-Ion batteries at least once every 6 months.
• The average lifespan of the battery is usually 300 charging
cycles, but this depends on the use. Total capacity will
slowly decrease after multiple charging cycles.
8. Folding handle
When the handle is extended, you can use the Looky4 as a
magnier. The closer you get to the object, the bigger the
magnication will be.
It is also possible to use the Looky4 with the handle folded in. You
can easily set the device on the table and it will automatically
stand at an angle. The magnication will then be about 8x. This is
easier when you want some stability during the reading of texts.
