Quick Start for Single Receiver

To reduce set-up time, the transmitter and receiver automatically link to form an audio channel the first time they are powered on and never have to be linked again.

Step

Step

Step

Connect power supply to the receiver and plug cord into an AC power source. Connect the

audio output to an amplifier or mixer.

Install charged transmitter batteries.

Turn on the transmitter and receiver. The blue rf LED will flash while the transmitter and re­ ceiver form a link. The rf LED turns solid blue when the link has successfully formed.

7/37

Shure Incorporated

Note: The transmitter and receiver will remain linked for future usage. At power-up, the blue rf LED and transmitter

LED will illuminate, skipping the linking step.

Check the audio and adjust the gain if necessary.
