Step 3: Install Batteries into Transmitter
①Accessing the Battery Compartment
Press the side tabs on the bodypack or unscrew the cover on the handheld as shown to access the battery compartment.
②Installing Batteries
AA Batteries: Place batteries (note polarity markings) and AA Adaptor as shown
Shure SB900 Battery: Place battery as shown (note polarity markings), remove AA Adaptor from bodypack transmitter,
stow AA Adaptor in door for handheld transmitter
Note: If using AA batteries, select a battery type from the transmitter menu to ensure accurate battery metering.
Step 4: IR Sync to Create an Audio Channel
Turn on the transmitter.
Press the sync button on the receiver. The red ir LED will blink indicating that sync mode is active.
Align the IR sync windows of the transmitter and receiver at a distance of <15 cm (6 in.). When the transmitter and re
ceiver are aligned, the red ir LED remains on and the sync will automatically occur.
sync good appears on the display when IR sync is complete. The blue rf LED will illuminate indicating that the transmit
ter is within range of the receiver.

Note: If the IR sync fails, repeat the IR sync procedure, carefully maintaining alignment between the IR windows of the transmitter and receiver.
Step 5: Sound Check and Gain Adjustment
Test the transmitter at performance levels while monitoring the audio meter and the audio LED. The audio meter should
display at least 3 bars and the audio LED should be green. Reduce the gain if there is audible distortion of the audio.
Increase or decrease the gain if necessary by pressing the arrow buttons on the receiver front panel.
Wearing the Bodypack Transmitter
Clip the transmitter to a belt or slide a guitar strap through the transmitter clip as shown.
For best results, the belt should be pressed against the base of the clip.
