Batteries
Expected life for AA batteries is up to 14 hours (total battery life varies depending upon battery
type and manufacturer).
When the LED indicator turns red, it signifies "low battery" with approximately 60 minutes of re-
maining battery life.
For alkaline batteries only. For rechargeable batteries, solid red means the batteries are dead.
To remove batteries from the handheld transmitter, push them out through the opening in the
microphone battery compartment.
Power Off
Press and hold the power button to power off the BLX2 or BLX4R. To
power off the BLX1, slide the power switch to OFF.
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.
Removing and Installing Identification

The BLX2 is equipped with a black identification cap from the factory
(dual vocal systems ship with additional gray cap).

To install: Align the cap and click into place. Replace battery cover.
An Identification Cap Kit containing assorted colored caps is available
