Troubleshooting

The remote control does 

not work

• Have you locked the remote control function? Unlock the 

function and try again.

• Check for incorrect battery orientation.
• Check for dead batteries.
• Check your distance and angle from the display.
• Check whether remote control is properly being pointed 

at the display’s remote control sensor window.

• Check for any obstacle between the remote control and 

the remote control sensor window. 

• Check that the remote control sensor window is not 

under strong fluorescent lighting, or in direct sunlight.

• Check for any devices (computer or personal digital 

assistant, PDA) nearby that transmit infrared signals which 

may cause interference to signal transmission between the 

remote control and the display. Turn off the infrared 

function of these devices.
