Connections

Connect various external devices to the TV and switch input modes to 
select an external device. For more information of external device’s 
connection, refer to the manual provided with each device.

Antenna/Cable

Connect the TV to a wall antenna socket with an RF cable (75 Ω).

 • Use a signal splitter to use more than 2 TVs.
 • If the image quality is poor, install a signal amplifier properly to 

improve the image quality.

 • If the image quality is poor with an antenna connected, try to realign 

the antenna in the correct direction.

 • An antenna cable and converter are not supplied.
 • For a location that is not supported with ULTRA HD broadcasting, 

this TV cannot receive ULTRA HD broadcasts directly. (Depending on 
model)

Satellite dish

Connect the TV to a satellite dish to a satellite socket with a satellite RF 
cable (75 Ω). (Depending on model)

CI module

View the encrypted (pay) services in digital TV mode. (Depending on 
model)

 • Check if the CI module is inserted into the PCMCIA card slot in the 

right direction. If the module is not inserted properly, this can cause 
damage to the TV and the PCMCIA card slot.

 • If the TV does not display any video and audio when CI+ CAM is 

connected, please contact to the Terrestrial/Cable/Satellite Service 
Operator.

Other connections

Connect your TV to external devices. For the best picture and audio 
quality, connect the external device and the TV with the HDMI cable. 
Some separate cable is not provided.

(Depending on model)
DTS (44.1 kHz / 48 kHz / 88.2 kHz / 96 kHz),

 - Off: Support 4K @ 50/60 Hz 8 bit (4:2:0)

If the device connected to Input Port also supports ULTRA HD Deep 
Colour, your picture may be clearer. However, if the device doesn’t 
support it, it may not work properly. In that case, change the TV’s 
[HDMI ULTRA HD Deep Colour] setting to Off.

USB

Some USB Hubs may not work. If a USB device connected through a USB 
Hub is not detected, connect it directly to the USB port on the TV.

 • Use USB 1 port when connecting a webcam. USB 2 port may not 

support some webcam. (Depending on model)

 • It is recommended that you use a USB hub or USB HDD with a power 

supply. (If the power supplied is not sufficient, the USB storage device 
may not be detected properly.)

 • It is recommended that you use an external USB HDD with a rated 

voltage of 5 V of less and a rated current of 500 mA or less.
