SERIAL NUMBER

Nothing plays on the HR73 and The display reads "F
no F" or "C no F" what does this mean?

It means that you have no MP3 fi les in memory to play. "F no F "
means the internal memory has no fi les to play and "C no F" means
the SD card has no fi les to play. If you get this message you are in
the MP3 mode play format. Try changing to VOC mode format on
the HR73. If there are VOC fi les on the card previously recorded
you must play them back in the VOC mode of the HR73. The fi les
recorded on VOC can only be played back in VOC mode. This ap­plies to internal and external memory.

I get no sound from the STEREO OUTPUTS?

Make sure the VOL level is turned up if the level is at 0 you will hear
no sound out of the Stereo Outputs.

IN VOC MODE I cannot get the repeat all function to
light.

The HR73 does not REPEAT ALL in voc mode.

When I plug the HR73 into my computer the display
does not light as bright as when the power adapter is
used?

When using the USB jack from your computer to power the HR73
the display might be much dimmer this is normal. This is the proper
way to exchange fi les to and from your computer. Plugging in the
power adapter to the HR78 while using the USB from your com­puter is not recommended, as it may damage the HR78 or you
computer.

FAQ:

What is VOC?

The VOC is a mp3 fi le with a unique fi le name. When you record on
the internal memory or SD card the HR73 has to keep the tracks in
order it does this by giving the MP3 a fi le name like M_INT_XX.mp3
for the internal memory or M_EXT_XX. mp3 for the SD card. If
these fi le names were not used the HR73 would have no way of
knowing what track order they were recorded to or how to play
them back. The last page of the manual explains this in better de­tail.

Why can I not record onto my computer from the
HR73?

When you plug the HR73 into your USB on your computer you can
only access the internal memory of the HR73. It will not access the
SD card nor can you record onto your computer in real time. You
must record your fi les on to the internal memory then transfer them
via USB to your computer.

Mic inputs (no LINE IN indication), or the rear panel Line In inputs (shows LINE IN status).

• Flash or Card Memory Indicator: An "F" before the Track Time indicates the program material is
stored in the MP3 Recorder's internal Flash memory. A "C" in that place indicates the material is
stored onto the SD Card.

RECORDING TO INTERNAL MEMORY:

Recording from the Line Inputs

When I plug the HR73 into my computer I cannot ac­cess the SD card plugged into the HR73?

The USB from the HR73 will not access the SD card. The only
function of the USB output of the HR73 has is to access the internal
memory of the HR73. Once the HR73 is plugged into a computer
USB port all buttons on the front of the HR73 become inoperable.

How much play time does the internal memory have
for recording?

You can record for 116 minutes with the internal memory. Sample
rate 44.1 Khz, 128K bps.

Can I record onto a thumb drive?

No, The only record options for the HR73 are the internal memory
or on to an SD card.

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).

While recording you can monitor the signal with the EAR 1/8" jack by plugging stereo headphones
into the HR78. Note there is no volume control for the EAR level nor is there a volume control for the
line in signal being recorded by the HR73. The EAR monitoring is only active when the RECORD is
depressed all other times you will not hear anything out the EAR for monitoring except on playback.

The HR73 has 99 tracks that can be used in any order.

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".

Note: You can only use mono (tip-sleve)1/4" mic jack for plugging into the HR78.

You cannot plug condenser mic's into the HR78.
The EAR monitoring is only active when the RECORD is active.
The left mic input jack will send a signal to the left and right. If you plug a single mic into the
Right mic input you will only get a right output. Using the left and right together will give you
a separate left and right output.

RECORDING DIRECTLY TO AN SD CARD:

USB OPERATION / FILE MANAGEMENT

-To record directly to the SD card the HR73 must be in VOC mode.- After an SD card is inserted
the display will indicate the letter "C" to verify 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 separate 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.

PLAYBACK

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.

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 120M, 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.

Make sure all proper connections are made; Line Outs are connected to a mixer or amplifi er, the EAR
out is connected to stereo earphones or headphones. Please note that there is no level control on the
HR73 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.

Select the track you wish to listen to, press the PLAY button to begin playback. If you wish to change
the Equalizer settings, press the STOP button to stop playback. Press the MODE button, then press
the A-B/EQ button repeatedly until you reach the desired EQ setting. Press MODE to exit and return
to normal mode.
If you wish to hear a certain portion of the program material repeated; begin playing the track, when
the material reaches the beginning of the part you want repeated, press the A-B button. When the
material reaches the ending of the part you want repeated, press the A-B button again. This portion
of the material will then playback repeated continuously until either the A-B button is pressed again,
or the STOP button is pressed.

Remember; only fi les in the VOC format may be played back in VOC mode, all other mp3 fi les will be
played back in MP3 mode.
