Communication problems may occur if infrared communication equipment (e.g.,
infrared cordless headphones) is used near the TV. Please use headphones other
than infrared cordless headphones. Also, if you use infrared communication
equipment other than infrared cordless headphones, move the infrared transceiver
away from the TV until the noise is eliminated, or move the transmitter and
receiver of the infrared communication equipment closer together.

The TV's audio might be set to Auto SAP or Mono, when it might be better set to
Stereo. In the Audio menu (see page 63), set the MTS setting to Stereo. If
already set to Stereo, switch to Mono (which may reduce background noise
during weak stereo broadcasts).
❏
If the Speaker option is set to Off and the Audio Out option is set to Fixed (in
order to output the sound to your audio system) use your audio receiver to adjust
the sound (see page 63). Or, to use the TV remote control, set the Audio Out
option to Variable.
