• Press the POWER button to activate the instrument.

5.1.4 Loading the Tray

• Carefully place the lower tray into the bath.
• Ensure it is positioned properly to avoid imbalance.

5.1.5 Selecting Sonic Mode

• Press the MODE button to select the SONIC function.
• Adjust the sonic strength according to the requirement of the sample.

5.1.6 Setting Time

• Use the MODE button to select TIME.
• Adjust the duration using the UP/DOWN buttons based on process needs.

5.1.7 Setting Temperature

• Select TEMP using the MODE button.
• Set the required temperature using the UP/DOWN controls.

5.1.8 Starting the Process

• After configuring all parameters, press the START/STOP button to begin sonication.
• Monitor the process periodically to ensure proper functioning.

5.1.9 Stopping and Shutdown

• Once the process is complete, remove items carefully.
• Press START/STOP to stop the operation.
• Turn off the instrument using the POWER button.
