Recovery Process

In the event of a battery failure while the unit is re-
cording, a recovery process is available to restore 
the recording in proper format. When a new battery is 
installed and the unit is turned back on, the recorder 
will detect the missing data and prompt you to run the 
recovery process. 

The file must be recovered or the 

card will not be usable in the SMWB.

First it will read:

Interrupted Recording 

Found

The LCD message will ask:

Recover? 

for safe use 

see manual

You will have the choice of 

No

 or 

Yes

 (No is selected 

as the default). If you wish to recover the file, use the 
DOWN arrow button to select 

Yes

, then press MENU/

SEL.  

The next window will give you the option to recover all 
or part of the file. The default times shown are the best 
guess by the processor where the file stopped record-
ing. The hours will be highlighted and you can either 
accept the value shown or select a longer or shorter 
time. If you are unsure, simply accept the value shown 
as the default.  

Press MENU/SEL and the minutes are then highlighted. 
You can increase or decrease the time to be recovered. 
In most cases you can simply accept the values shown 
and the file will be recovered. After you have made your 
time choices, press MENU/SEL again.  A small 

GO!

 

symbol will appear next to the DOWN arrow button. 
Pressing the button will initiate the file recovery. The 
recovery will happen quickly and you will see:

Recovery 

Successful

Special Note:

Files under 4 minutes long may recover with additional 
data “tacked on” to the end of the file (from previous 
recordings or data if the card had been used previ-
ously). This can be effectively eliminated in post with a 
simple delete of the unwanted extra “noise” at the end 
of the clip. The minimum recovered length will be one 
minute. For example, if the recording is only 20 seconds 
long, and you have selected one minute there will be 
the desired 20 recorded seconds with an additional 40 
seconds of other data and or artifacts in the file. If you 
are uncertain about the length of the recording you can 
save a longer file - there will simply be more “junk” at 
the end of the clip. This “junk” may include audio data 
recorded in earlier sessions that were discarded.   This 
“extra” information can be easily deleted in post produc-
tion editing software at a later time.
