Recovery Process
Recordings can be reliably recovered even if the card is
accidentally removed or the battery dies while a record-
ing is in progress. If a recording is interrupted, all of the
audio is present on the card and can be easily recov-
ered by the MTCR. The MTCR keeps track of the length
of the most recent recording so it can supply a good
suggestion for the length to recover. If the length is ever
unknown or the MTCR’s suggestion seems incorrect, it
is always possible to override the suggested length. If
in doubt, specify the maximum length possible, in which
case the entire remainder of the card is recovered. All
of the interrupted recording will be present, followed by
extra contents which might be random noise or audio
from previously deleted recordings.
NOTE: A good battery is required to begin the
recovery process. If recovery is attempted with a
weak battery, a message appears saying that a
fresh battery will be required.
Once a fresh battery has been installed, power on the
MTCR and insert the card with the interrupted record-
ing. The MTCR will detect the interrupted recording and
display.

See manual
If “No” is chosen, nothing is done to the card and
the MTCR will not use the card. If “Yes” is chosen”, a
prompt appears asking for the length of the recording
to recover, specified as a number of hours and minutes.
The default suggestion will be the approximate length
of the most recent recording. It is always safe to re-
cover a longer recording than was made. To specify the
recovery time, use the MENU/SEL button to navigate
and specify the hours and minutes fields. Once set as
desired, use MENU/SEL to navigate to the “GO!” soft
button and press the DOWN arrow button to begin the
recovery process.
Recovery is nearly instantaneous. When completed, the
display will show

3) The recorder will boot up into the firmware update
mode with the following options on the LCD:
•
Run
- Exits the update mode and starts up the
recorder in the normal operating mode.
•
Update
- Displays a scrollable list of the .ldr files
on the card.
•
Power Off
- Exits the update mode and turns the
power off.
NOTE: If the unit powers on normally instead of
offering the options in Step 3 (above), power the
unit off and try again, making sure that both arrow
buttons are firmly depressed while powering the
unti back on.
4) Select
Update
. Use the UP and DOWN arrow
buttons to select the desired file and press MENU/
SEL to begin the update process. The LCD will
display status messages while the firmware is being
updated.
NOTE: The Update process takes about
20 seconds.
5) When the update is complete, the LCD will display
this message:
UPDATE SUCCESSFUL REMOVE
CARD.
After the card is removed, the LCD will
return to the three options shown in step 3 above.
6) Select
Power Off
and press MENU/SEL to finish
the update.
7) If you re-insert the same card and turn the power
back on for normal use, the LCD will display a mes-
sage prompting you to format the card:
Format Card?
(files lost)
• No
• Yes
If you wish to record audio on the card, you must
re-format it. Select
Yes
and press MENU/SEL to
format the card. When the process is complete, the
LCD will return to the Main Window and be ready
for normal operation.
If you choose to keep the card as is, you may re-
move the card at this time.
The firmware update process is managed by a boot-
loader program - on very rare occasions, you might
need to update the bootloader.
•
MTCRboot vX_xx.ldr
is the bootloader file
Follow the same process as with a firmware update and
select the MTCRboot file. Be forewarned, this can cor-
rupt your unit if interrupted. Don’t update the bootloader
unless advised to do so by the factory.
