To power on the receiver, press the power button. The display will illuminate. To power on the BLX2/SM58 transmitter, press and hold the power button on the transmitter until the LED indicator lights up green.
4.2. Channel Scan and Synchronization
Ensure all transmitters are off before performing a channel scan on the receiver. Press the 'Group' button on the receiver to initiate an automatic scan for the best available group and channel. Once the receiver displays a stable group and channel, turn on your BLX2/SM58 transmitter. Open the battery compartment to access the group and channel buttons.

4.3. Audio Level Adjustment (Gain)
Test the audio by speaking into the microphone at typical performance levels. Observe the audio LED on the receiver. If the LED is consistently red, the audio input is too high (overload). To adjust the gain on the BLX2/SM58 transmitter, open the battery compartment. If the receiver audio LED is consistently red, press and hold the 'channel' button for 5 seconds until a dot appears next to '-10 dB' on the transmitter's display. This activates the -10 dB pad, reducing the input sensitivity. If the LED remains green, the levels are normal.
