Cause
When you reset the R-05 to its factory settings, all settings made using the "Menu" screen
or the like will return to their original values. Please make the desired settings again.
If the R-05's power is turned off without using its power switch (e.g., by a battery failure
or disconnected AC adaptor), the settings you made will return to their original values.
Please make the desired settings again.
The R-05 will not be recognized by your computer if you connect it when the "Menu"
screen is displayed, or during playback or recording. Please disconnect the USB cable,
and try again.
Even if the file name extension is .MP3 or .WAV, the display when selecting a file will be
slower if the file is damaged, if the file is an invalid file or an unsupported type of MP3,
or if the file is of a large size. This occurs because the R-05 needs to determine whether
it is able to play the file.
If you're monitoring the recording through open-air type headphones, acoustic
feedback might occur if the R-05's mics pick up the sound from your headphones. The
R-05's built-in mics are able to detect even faint sound, so keep your headphones away
from the built-in mics.
If the AC adaptor is connected or if batteries are installed, the internal clock will obtain
its power from those sources. If several days pass with the batteries removed and the
AC adaptor disconnected, the internal clock will return to its default setting. When you
turn on the power in this state, the message "Clock Initialized" will appear. If this
message appears, please reset the date and time.
The SD card must have twice as much free space as occupied by the corresponding
file(s). It is not possible to join files that would exceed 2 GB in size.
