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.
