CAUTION:

When the AUDIO INPUT LINE/MIC switch on the rear section is set to MIC, be sure to check that the microphone is connected to the AUDIO IN FRONT or AUDIO INPUT REAR connector. If the microphone is not connected, increasing the audio input level could cause noise from the input connector to be recorded on the tape. When the microphone is not connected to the front AUDIO INPUT or rear AUDIO INPUT connector, set the LINE/MIC switch to LINE or turn down the audio input level control.
