view’ on page 55

A two-tone signal is output if any error occurs. The red LED on the

device also lights.

In the case of an error, switch off the device at the mains power

switch. If the error occurs again after restarting the device, note the

error code and contact LAUDA Service Constant Temperature

Equipment. Contact details can be found in

Chapter 12.3
