Aim the remote control directly at the infrared sensor window on the front of the unit.
•
Reduce the distance to the unit.

Re-insert the batteries with their polarities (+/– signs) as indicated.
•
When there is an infrared-equipped device such as PC near this unit, it may interrupt the remote
control signal of this unit.
•
Move the infrared-equipped device away from this unit, change the angle of the infrared sensor or
turn off the infrared communication function.
•
Connect the RF coaxial cable to the unit directly and run the initial setup.
•
Make sure to complete the channel scan before the unit goes into standby mode.

When using the Component Video Connection check that the Green (Y), Blue (Pb/Cb) and Red (Pr/
Cr) connectors are connected to their corresponding colored jacks on the unit.

•
Captions that are delayed a few seconds behind the actual dialog are common for live broadcasts.
Most captioning production companies can display a dialog to maximum of 220 words per minute. If
a dialog exceeds that rate, selective editing is used to insure that the captions remain up-to date with
the current TV screen dialog.
