While Timer mode is in operation, you can increase or decrease the time
setting as required by pressing the ”1” key (6) and/or the ”10” key (5)
as described above. After you have changed the time setting, the time
begins to elapse again and the LED display (2) shows the remaining time
in minutes as it did before.
Blocking or overloading the motor beyond the permissible motor tem-
perature causes the device to switch off automatically due to the safety
circuit. The LED display (2) displays the corresponding error message. To
eliminate the error, please check the operating conditions. Also allow
the device to cool off.
The device must be turned off and back on again.
Error message MTS 2/4:
Please note! If an error occurs, an audio warning signal is generated and
the Timer display switches to E + error number. First try to turn off the
device and then turn it back on to continue operation. If an error is not
eliminated even after waiting for a considerable amount of time, please
contact our service department.
You should always let us know what error code was displayed.
