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.
