RECORDING TO INTERNAL MEMORY:

Recording from the Line Inputs
If "Line In" is  not already shown in the display, press MODE then the UP/LINE button The display 
should indicate "LINE IN".  Make sure a blank track is selected. Press REC, and send a signal to the 
MP3 Recorder. The circle next to the track number will blink twice, then recording begins. Keep this 
delay period in mind so you don't lose program material at the beginning of a track. When you are 
fi nished recording, press the STOP button. These fi les are automatically saved as VOC fi les, and are 
in the format indicated on the last page of this guide (there is no recording in MP3 mode).

Recording from the Mic Inputs
If "Line In" is indicated in the display, press MODE then the UP/LINE button to enable the MIC INputs 
on the front panel. Connect your microphone(s). Proceed as indicated above in "Recording from the 
Line Inputs".

RECORDING DIRECTLY TO AN SD CARD:

-To record directly to the SD card the HR73 must be in VOC mode for both recording and playback.- 
After an SD card is inserted the display will indicate the letter "C" to varify that an SD card is present. 
Select VOC mode on the display. Select a track (1-99) to record to. If the track is already fi lled you 
must fi rst delete the track to record. All other functions of recording are as stated above (there is no 
recording to the SD card in MP3 mode).

IMPORTANT NOTE FOR SD CARD RECORDING:

 

The SD card when recorded to directly with the HR73 will split the card into two seperate sections 
MP3's and VOC's both are explained on the last page of this manual. If the SD card had MP3 fi les on 
it they will remain the same after using the HR73 to record directly in VOC mode you will end up with 
both MP3's and the VOC fi les on the SD card. Playback of MP3's can only be done when the HR73 
is set to MP3 mode also VOC fi les can only be played back in VOC mode.
