When viewing 3D images, you can slide the switch 
between 2D and 3D modes. This is useful when several 
people are viewing 3D images on the same TV with 
some people wanting to watch in 3D and some people 
wanting to watch in 2D.

■

When you slide the switch to 2D while viewing 3D 
images, the 3D images switch to 2D images.

■

When you slide the switch to 3D while viewing 2D 
images, the 2D images switch to 3D images.

The 3D Glasses can be used by receiving an infrared 
signal sent from the TV.
The 3D Glasses turn off automatically after 10 minutes if 
no signal is received from the TV.

■

From directly in front of the 3D infrared emitter on 
the TV: approx. 5 m (within approx. 30° horizontally 
and 20° vertically)

When the battery power is low, the LED light blinks one 
time per second. If the 3D glasses battery runs out, you 
can recharge the 3D glasses battery by connecting the 
supplied USB cable to the TV and the power-supply 
terminal on the 3D glasses.

 

Turn off the TV, and then slide the switch on the 
3D glasses to OFF.

 

Connect the cable shown below before turning 
on the TV.
•  The LED light blinks once per two seconds, and 

then starts recharging.

•  When the LED light goes off, the recharge is 

complete. It takes 90 minutes to complete the 
recharge.

•  Insert the USB cable again if the LED light blinks 

on and off once every 0.5 seconds. If it still 
doesn’t respond, inquire with a retail dealer or 
SHARP customer service. 

 

After the recharge has completed, turn off the 
TV, and then remove the USB cable from the 3D 
glasses.

•  Do not recharge while wearing the 3D glasses.

•  Be sure to turn on the TV when you recharge the 3D 

glasses battery. If the TV is turned off, you may not 
recharge it.

•  When you recharge the 3D glasses battery, only 

connect the USB cable (supplied accessory) to the 
USB terminal on the TV.

•  The battery will not recharge during usage with the 

USB cable connected. 

•  Recharge the battery within the operating temperature 

(10°C–40°C). The battery may not be able to recharge 
outside of the operating temperature.

You can use the 3D glasses with an external power 
supply when you slide the switch on the 3D glasses 
to 3D or 2D in step 1 in Recharging the 3D glasses 
battery

 (recharging will not complete).

•  Do not move around while wearing the 3D glasses. 

You may result in getting your feet caught in USB 
cable, the TV falling or other accidents that may cause 
injury.

•  When you use the USB cable connecting the 3D 

glasses, careful not to get your feet caught in the USB 
cable. It may result in falling or other accidents that 
may cause injury.

•  These 3D Glasses are only for use with SHARP LCD TVs supporting 3D.

■

•  Do not apply pressure to the lenses of the 3D Glasses. Also, do not drop or bend the 3D Glasses.
•  Do not scratch the surface of the lenses of the 3D Glasses with a pointed instrument or other object. Doing so may 

damage the 3D Glasses and reduce the quality of the 3D image.

•  Use only the cloth provided with the 3D Glasses to clean the lenses.

■

•  Do not allow the infrared receiver to become dirty, and do not attach stickers to or otherwise cover the infrared 

receiver. Doing so may prevent the receiver from operating normally.

•  If the 3D Glasses are affected by other infrared data communication equipment, the 3D images may not be 

displayed correctly.

■

•  Do not use devices that emit strong electromagnetic waves (such as cellular phones or wireless transceivers) near 

the 3D Glasses. Doing so may cause the 3D Glasses to malfunction.

•  The 3D Glasses cannot operate fully at extreme high or low temperatures. Please use them within the specified 

usage temperature range.

•  If the 3D Glasses are used in a room with fluorescent lighting (50/60 Hz), the light within the room may appear to 

flicker. In this case, either darken or turn off the fluorescent lights when using the 3D Glasses.

•  Wear the 3D Glasses correctly. 3D images will not be correctly visible if the 3D Glasses are worn upside down or 

back-to-front.

•  Other displays (such as computer screens, digital clocks, and calculators) may appear dark and difficult to view while 

wearing the 3D Glasses. Do not wear the 3D Glasses when watching anything other than 3D images.

•  If you lie on your side while watching the TV with 3D Glasses, the picture may look dark or may not be visible.
•  Be sure to stay within the viewing angle and optimum TV viewing distance when watching 3D images. Otherwise, 

you may not be able to enjoy the full 3D effect.

•  The 3D Glasses may not work properly if there is any other 3D product or electronic devices turned on near the 

glasses or TV. If this occurs, turn off the other 3D product or electronic devices or keep the devices as far away as 
possible from the 3D Glasses.

•  Stop using this product in any of the following situations:

 

− When images consistently appear doubled while you are wearing the 3D Glasses

 

− When you have difficultly perceiving the 3D effect

•  If the 3D Glasses are faulty or damaged, stop using them immediately. Continued use of the 3D Glasses may cause 

eye fatigue, headaches and illness.

•  If you have any abnormal skin reaction, stop using the 3D Glasses. In very rare instances, such reactions may be 

due to an allergic reaction to the coating or materials used.

•  If your nose or temples become red or you experience any pain or itchiness, stop using the 3D Glasses. Pressure 

caused by long periods of use may lead to such reactions and may result in skin irritation.

•  Images displayed in 3D mode 

appear doubled while you are 
wearing the 3D Glasses.

•  Is the power of the 3D Glasses turned on?
•  Slide the switch to 3D to turn on the 3D Glasses.

•  Images displayed in 3D mode 

appear 2D while you are wearing 
the 3D Glasses.

•  Are the 3D Glasses set to 2D mode?
•  Slide the switch to 3D while viewing 2D images and the 2D images 

switch to 3D images.
