Operating Instructions

Channel Selection

To ensure optimal performance and avoid interference, it is crucial to select the best available channel for your wireless system. The BLX system features a one-touch QuickScan frequency selection function that quickly locates the best open frequency.

1. Turn on the receiver. Ensure the transmitter is OFF at this time.
2. Press the "Group" button on the receiver to scan for the best group and channel. The receiver will automatically perform a channel scan and select the best available channel.
3. Turn on the transmitter. Open the battery compartment to access the group and channel buttons.
4. Set the transmitter to the same group and channel as displayed on the receiver.
5. The "Ready" LED on the receiver should illuminate green, indicating a successful connection.

Adding Multiple Receivers (BLX88)

If you are using a BLX88 dual-channel receiver or adding multiple BLX4 receivers, the group scan function on the BLX88 will set up both channels simultaneously. For individual BLX4 receivers, ensure each is set to the same group but a different channel to prevent interference.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the microphone and receiver. Avoid using harsh chemicals or abrasive materials.
• Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure uninterrupted performance. Always use fresh AA alkaline batteries or fully charged rechargeable batteries.
• Storage: Store the system in a cool, dry place away from extreme temperatures and humidity when not in use.
