*For alkaline batteries only. For rechargeable batteries, solid red means the batteries are dead. Single System Setup 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. 1. Press and release the group button on the receiver. The receiver scans for the clearest group and proceeds to channel scan. Note: If you want to stop the scan, push the group or channel button. 2. Turn on transmitter and change the group and channel to match the receiver (See Manually Setting Group and Channel). Once the receiver is set up, perform an audio check on the microphone.

While the display is flashing, press the the display begins to flash. group button again to advance to the next group. Note: Only the group setting will be dis-

played during the manual setup. 3. Once the desired group is reached, release the group button. Then the receiver will au-

While the display is flashing, press the group button again to advance to the desired group setting. Channel (number) If channel needs to be changed, follow the same procedure using the channel button instead of the group button. Note: When the group and channel correctly match the receiver, the ready LED on receiver illuminates. display flashes. Multiple System Setup 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 is 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:

1. Perform a group scan. This finds the group with the most clear channels. Note: For the BLX88, the group scan sets up both receivers at the same time. 2. Turn on the first transmitter and change the group and channel to match receiver. 3. Leave the transmitter on and continue with the additional systems. For each additional receiver:

1. Use manual setup to change the receiver to match the group setting of the first receiver. Recall that each time the group setting is changed, a channel scan is automatically done. 2. Turn on the transmitter and change the group and channel to match the receiver. 3. Leave the transmitter on and continue to the next system. 4. Once all receivers are set up, perform an audio check on all microphones. Locking and Unlocking Controls Lock system controls to prevent accidental setting changes or power off. Transmitter Turn the transmitter on. Hold the group button, then press the channel button for approximately 2 seconds. The LED indicator rapidly flashes amber when locked and green when unlocked. Receiver Turn the receiver on. Simultaneously press the group and channel button to lock or unlock. The display flashes rapidly. When locked, the LED display flashes rapidly if any key is pressed. The BLX88 can be locked from either side for both sides. 4 Wireless Tips to Improve System Performance If you encounter wireless interference or dropouts, try the following suggestions:

Replace the transmitter batteries Choose a different frequency channel Reposition the antennas so there is nothing obstructing a line of sight to the transmitter (including the audience) Avoid placing transmitter and receiver where metal or other dense materials may be present Move the receiver to the top of the equipment rack Remove nearby sources of wireless interference, such as cell phones, two-way radios, computers, media players, and digital signal processors Keep transmitters more than two meters (6 feet) apart Keep the transmitter and receiver more than 5 meters (16 feet) apart Keep them away from large metal objects During sound check, mark trouble spots and ask presenters or performers to avoid those areas Getting Good Sound Correct Microphone Placement Hold the microphone within 12 inches from the sound source. For a warmer sound with increased bass presence, move the microphone closer. Do not cover grille with hand. Wearing the Headworn Microphone Position the headworn microhpone 13 mm (1/2 in.) from the corner of your mouth. Position lavalier and headworn microphones so that clothing, jewelry, or other items do not bump or rub against the microphone. 13 mm

(.5 in.) Adjusting Gain Monitor the audio LED indicator on the receiver front panel when setting the transmitter gain. Green: normal levels Red: excessive sound levels (overload). BLX1 Use the thumb wheel on the inside of the bodypack bat-

tery door to adjust the gain up (+) or down () until desired level is reached. For instruments, turn gain to minimum setting. For lavaliers, increase the gain as desired. The audio LEDs on the receiver should illuminate when you speak into the microphone or play your instrument. The red LED should only illuminate infrequently when you speak loudly or play your instrument loudly. 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. 1. 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. 2. To change the gain back to default, hold the channel button again for 5 seconds, or until the dot disappears. group channel

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: Danger of explosion if battery incorrectly replaced. Operate only with Shure compatible batteries. WARNING: Battery packs shall not be exposed to excessive heat such as sunshine, fire, or the like. 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. Power Off 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. Removing and Installing Identification Caps The BLX2 is equipped with a black identification cap from the factory (dual vocal systems comes with a black and gray cap). To remove: Remove battery cover. Squeeze sides and pull off cap. To install: Make sure the tab matches the slot on the bot-

tom of the handheld and click into place. Replace battery cover. An optional Identification Cap Kit containing 9 colored caps is available (see Optional Accessories). 6 Troubleshooting Issue No sound or faint sound Indicator Status Receiver ready LED on Receiver ready LED off Solution Verify all sound system connections or adjust gain as needed (see Adjusting Gain) Verify that the receiver is connected to mixer/

amplifier Turn on transmitter Make sure the batteries are installed correctly Perform transmitter setup (see Single System Setup) Insert fresh batteries Receiver LED screen off Make sure AC adapter is securely plugged into electrical outlet. Make sure receiver is powered on. Audio artifacts or dropouts Transmitter indicator LED flash-

ing red Ready LED flickering or off Replace transmitter batteries (see Changing Batteries). Change receiver and transmitter to a different group and/or channel. Identify nearby sources of RF interference, and shutdown or remove source. Replace transmitter batteries. Ensure that receiver and transmitter are positioned within system parameters System must be set up within recommended range and receiver kept away from metallic surfaces. Transmitter must be used in line of sight from receiver for optimal sound Distortion Sound level variations when switching to different sources Receiver/transmitter won't turn off Audio LED on receiver indi-

cates overload (red) N/A Reduce transmitter gain (see Adjusting Gain). Adjust transmitter gain as necessary (see Adjusting Gain). LED/display flashing rapidly See Locking and Unlocking Controls.
