Note: Your system comes with a combination of the following components.
If setting up additional systems, leave the first transmitter and receiver on. For each additional receiver, manually set the group to match the first receiver. Note: The receiver will automatically perform a channel scan to find an available frequency after the group has been selected. Set the transmitter frequency to match the receiver.

| LED Indicator | Status |
|---|---|
| Green | Ready |
| Rapidly Flashing Red | Controls locked |
| Solid Red | Battery power low (less than 1 hour remaining*) |
| Flashing Red and shuts off | Batteries dead (change batteries to power on transmitter) |
*For alkaline batteries only. For rechargeable batteries, solid red means the batteries are dead.
Before you begin, turn off all transmitters and turn on any equipment (other microphones or personal monitoring systems) that could cause interference during the performance.
The receiver scans for the clearest group and channel.
Note: If you want to stop the scan, push the group button again.
Once the system is set up, perform an audio check and adjust the gain if necessary.
Transmitter group and channel must be manually set to match the receiver.
If channel needs to be changed, follow the same procedure using the channel button instead of the group button.
Note:
Up to 12 systems can operate simultaneously (band and RF environment dependent).
Important: Set up each system one-at-a-time. Once a receiver and transmitter are tuned to the same group and channel, leave the transmitter powered on. Otherwise, scans from the other receivers will not detect that channel as occupied. For the BLX88, be sure to setup both transmitters before progressing to the next receiver.
Turn on any other equipment that could cause interference during the performance so it will be detected during the group and channel scans in the following steps.
Before you begin system set up, turn all receivers ON and all transmitters OFF.
For the first receiver:
This finds the group with the most clear channels.
Note: For the BLX88, the group scan sets up both receivers at the same time.
Note: If the selected group does not contain enough open channels, manually select group "d" when setting up larger systems.
For each additional receiver:
The receiver group may need to be changed as part of a multiple system setup.
Note: Only the group setting will be displayed during the manual setup.
Always use a channel selected by the channel scan. However, if necessary, the channel can be set manually. Follow the same steps above using the channel button instead of the group button.
Lock system controls to prevent accidental setting changes or power off.
Turn the transmitter on. Hold the group button, then press the channel button for approximately 2 seconds. The LED indicator rapidly flashes red when locked.
Turn the receiver on. Simultaneously hold the group and channel button. The display flashes rapidly.
If you encounter interference or dropouts, try the following suggestions:
Monitor the audio LED indicator on the receiver front panel when setting the transmitter gain.
The red LED should only illuminate infrequently when you speak loudly or play your instrument loudly.
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.
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.
A dot appears on the lower right-hand corner of the LED display, which indicates −10 dB gain setting has been activated.
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.
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.
WARNING: Battery packs shall not be exposed to excessive heat such as sunshine, fire, or the like.
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.
Hold down the power button to power off the BLX2 or BLX4/88. To power off the BLX1, slide the power toggle switch to OFF.
The BLX2 is equipped with a black identification cap from the factory (dual vocal systems ship with additional gray cap).
To remove: Remove battery cover. Squeeze sides and pull off cap.
To install: Align the cap and click into place. Replace battery cover.
An Identification Cap Kit containing assorted colored caps is available as an optional accessory.
