USB OPERATION / FILE MANAGEMENT

Please be aware that if you are connecting this unit to a computer with an operating system of
Windows 98 or below - you must visit our website at www.rolls.com to download and install the
USB driver.
Windows XP recognizes, and automatically installs the driver, and will recognize the MP3 Re­corder. Once the USB cable is connected, the MP3 Recorder internal memory is displayed as
one drive. If an SD card is installed - it comes up as a separate drive. For example; the internal
memory might be drive D, and the SD card assigned drive E.

NOTE: The front panel buttons (except the POWER switch) of the MP3 Recorder do not function
when the unit is connected via USB to a computer.

VOC Mode files
In order for files to be accessed in VOC mode, they MUST be stored in the following format:
M_INT_XX.mp3 for internal memory
M_EXT_XX.mp3 for external or SD card storage.
XX stands for the track number - these must be .mp3 files for playback.

MP3 Mode files
.mp3 files may be stored in either memory (internal or SD card) without renaming them, but they
may only be accessed in MP3 Mode.

Maximum memory for the internal drive is 64M, maximum memory for the SD drive is 512M.

To DELETE files - select the file you wish to delete, press the MODE button and press the ">>
DEL" button. The display will read, "dEL". To delete the file, press the ">>/DEL button again.

is a one to two second delay while the unit switches memory.

the EAR out is connected to stereo earphones or headphones. Please note that there is no level
control on the HR73/RMS273 and that program material may be loud.

To switch from internal memory, to SD card memory press MODE, then the STOP button. There
is a one to two second delay while the unit switches memory.

again. This portion of the material will then playback repeated continuously until either the A-B

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.

A NOTE ON RECORDING LEVELS: The HR73/RMS273, like all digital recording devices, performs
at its best with a maximum input signal without clipping. This means that a weak, low-level recorded
signal will likely have artifacts or noticeable noise on it.
