Step7. Both TEK 51T-HD and TEK TPHD402PR have IR IN and OUT. When one model
is used for IR signal receiver, the IR signal must be sent out by the other model.
For example
: When “IR IN” of TEK 51T-HD connects with an IR receiver, the IR
transmitter must connect to IR OUT of TPHD402PR.
The IR signal can be transmitted bi-directionally between TEK 51T-HD and
TEK TPHD402PR.
Step8. Select MIC level and connect right microphone to MIC input port. MIC audio will
be transmitted to AUDIO OUTPUT port and mixed with source audio.
Step9. Connect DC12V power adaptor to the power port (TEK TPHD402PR is able to
get power from TEK 51T-HD).
