The red LED should only illuminate infrequently when you speak loudly or play your instrument loudly.
BLX1
Rotate the audio gain adjustment to increase (+) or decrease (−) the gain until desired level is reached.
For instruments, turn gain to minimum setting. For lavaliers, increase the gain as desired.
BLX2
The BLX2 features two gain level settings, default and attenuated (-10 dB). The default setting is used for most
situations. If the receiver audio LED flickers red often, set the microphone to attenuated. Use the channel button to
change the gain setting.
Hold down the channel button for 5 seconds.
A dot appears on the lower right-hand corner of the LED display, which indicates −10 dB gain setting has
been activated.
To change the gain back to default, hold the channel button again for 5 seconds, or until the dot disappears.
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 remaining battery life.
