The wireless microphone requires a 9V block battery. Open the battery compartment on the microphone handle, insert the 9V battery, ensuring correct polarity, and close the compartment.
3. Attaching the Shoulder Strap
Attach the provided shoulder strap to the designated attachment points on the Vonyx ST010 unit. Ensure the strap is securely fastened before carrying the unit.
4. Powering On/Off
To power on the unit, switch the ON/OFF switch to the 'ON' position. The POWER indicator will light up. To power off, switch it to the 'OFF' position.

- Ensure the Vonyx ST010 unit is powered on.
- Switch on the wireless microphone.
- The RF indicator on the speaker unit should illuminate, indicating a successful connection.
- Adjust the VOLUME knob on the speaker unit to control the microphone's output level.

2. Playing MP3 Files via USB
