5.5 Switching the sonication on and off
Requirements
• The oscillating tank is filled.
• The mains plug is plugged into a power outlet with an earthed socket.
Procedure
1. Place the lid (if present) on the device.
2. Rotate the rotary knob for the ultrasound duration to the desired sonication time or
to the ∞ symbol for continuous operation.
» The ultrasound is switched on. You will hear the ultrasound noise.
» The green indicator lamp lights up
» If the rotary knob is not set to ∞, it will slowly move counter-clockwise, indicating
the remaining sonication time. As soon as it is set to “0”, the ultrasound switches off.
3. To switch off the sonication, rotate the rotary knob to “0” for the ultrasound duration.
» The green indicator light goes out.
Information
- You can turn the knob in both directions.
- You can extend, shorten or switch off the sonication at any time.
- The timer only works if mains voltage is present. Without mains voltage, the locking of
the rotary knob can hardly be felt.
