Connector

NOTE: See Connecting the Player, on page 10, for detailed information
about making connections.

Main Power Switch: This mechanical switch turns the BDT 2/BDT 20’s power

supply on or off. After you have made and verified all connections (see Connecting
the Player, on page 10), set this switch to the “On” position. If you will not be using

the player for an extended period of time, you can set this switch to the “Off” position
to save energy.

Power-Cord Connector: After you have made and verified all other connections,
plug the supplied AC power cord into this input and into an unswitched AC outlet.

Network Connector: To be able to use the BD-Live feature, connect this port to
your local area network (LAN) using a Cat. 5/Cat. 5e/RJ45 network cable. See
BD-Live Interactivity, on page 15, for more information.

HDMI Output (HDMI ver. 1.3a): Connect the BDT player’s HDMI output to the HDMI
input on your TV, audio/video receiver or surround-sound processor. The HDMI cable
transmits both video and audio, so if you’re connecting it directly to the TV and are
connecting the BDT 2/BDT 20’s coaxial digital audio output to a home theater audio
system, we recommend that you disable the BDT 2/BDT 20’s HDMI Audio Out to take
full advantage of the home theater audio system’s superior audio performance. See
Audio Settings: Audio Output, on page 13, for more information.

IMPORTANT: Your BDT 2/BDT 20 is in compliance with HDCP (High-Definition Copy
Protection). Your TV must also be HDCP-compliant to be used with the player’s HDMI
output. For the best results, we do not recommend HDMI connections in excess
of ten feet without a repeater. If your TV has a DVI input, you may use an optional
HDMI-to-DVI cable or adapter for the video connection to the TV. (The DVI connection
is video-only.)

Coaxial Digital Audio Output: Connect this output to the coaxial digital audio input
of your audio/video receiver or surround-sound decoder.

Fan Vents: The BDT 2/BDT 20 has a built-in fan to provide cooling air. To insure
proper operation, make sure that these vents are not blocked.
