CARE OF THE SCREEN
The screen of your TV can easily accumulate
dust or other residual particles depending on
its location; therefore, we recommend that you
clean it weekly.
1. To prevent fire or shock hazard, be sure
to turn off and disconnect your unit from
the AC power source when cleaning.
2. To clean your TV screen, use only a
completely dry microfiber cloth. Smoothly
wipe the surface of the screen horizontally
to avoid scratching the screen.
3. If the screen is excessively dirty, you can
moisten a cloth minimally with a solution
of mild soap and distilled water.
Do not use paper towels to clean the
screen, as they may damage and scratch
the surface.
4. Never spray any liquid directly on the
screen as it may penetrate the equipment
and cause irreparable damage.
5. Do not use products containing ammonia,
ethyl alcohol, acetone or ethylene chloride.
These components may damage the screen.
CARE OF THE CHASIS
Depending on the location of your TV, dirt may
accumulate very easily, so we recommend that
you clean hard-to-reach areas at least once
a month, such as ventilation slots or speaker
grilles, which are very prone to dust and lint:
1. The frame and back of the TV can be
cleaned using a cloth slightly moistened
with a mild soap and distilled water.
Clean the TV with gentle circular
movements to avoid scratching the outside
of the TV.
2. To remove dirt from the slots, use a
vacuum cleaner with a narrow nozzle
attachment at low power.
A cotton swab lightly moistened with
isopropyl alcohol can be used to
supplement the cleaning.
3. To clean the speakers, use a lint roller.
Dust particles will adhere easily.
CARE OF THE REMOTE CONTROL
The remote control continuously accumulates
dirt, dust or grease from hand contact. That’s
why for a correct functioning during its whole
life we recommend cleaning it at least once a
month.
1. First remove the batteries from their
compartment.
2. Turn the remote control and tap it gently
against the palm of your hand, with
the buttons facing down. This will help
loosen and remove any dirt that may
accumulate on the buttons.
3. Use a slightly moistened cloth with
warm water and a mild soap to clean the
remote control thoroughly.
Use a cotton swab or toothpick in the
narrow gaps and small spaces around
the buttons.
4. Finally, rub the remote control again
with a soft, dry cloth.
TO CLEAN THE TERMINALS
If the terminals get dirty, your TV may not
recognize easily the dierent attached sources.
To take care of the terminals follow the steps
below:
1. Turn off and disconnect your TV from
the AC power source and unplug any
other connected cables and appliances.
2. Use a vacuum cleaner with a narrow hose
attachment to clean the connections.
3. You may need a cleaning liquid in order to
clean the TV terminals and connections.
If that’s the case, we recommend the
use of isopropyl alcohol (99%). Although
alcohol can work too, it’s known to leave
some residue as it evaporates.
You should never use water nor any
water-based cleaning solutions to clean
the terminals.
4. Completely dry the terminals with a dry
cloth once cleaned and reconnect the
wires.
