Digital Hybrid Wireless Belt-Pack Transmitters
Rio Rancho, NM

Battery Installation
The transmitter is powered by AA batteries. (The SMWB
requires one AA battery and the SMDWB requires two.)
We recommend using lithium for longest life.
Because some batteries run down quite abruptly, using
the Power LED to verify battery status will not be reli-
able. However, it is possible to track battery status using
the battery timer function available in Lectrosonics
Digital Hybrid Wireless receivers.
The battery door opens by simply unscrewing the
knurled knob part way until the door will rotate. The
door is also easily removed by unscrewing the knob
completely, which is helpful when cleaning the battery
contacts. The battery contacts can be cleaned with
alcohol and a cotton swab, or a clean pencil eraser. Be
sure not to leave any remnants of the cotton swab or
eraser crumbs inside the compartment.
A small pinpoint dab of silver conductive grease* on the
thumbscrew threads can improve battery performance
and operation.
See page 20.
Do this if you experience a
drop in battery life or an increase in operating tempera-
ture.
If you are unable to locate a supplier of this type of
grease - a local electronics shop for example - contact
the factory for a small maintenance vial.
Insert the batteries according to the markings on the
back of the housing. If the batteries are inserted incor-
rectly, the door may close but the unit will not operate.
Formatting SD Card
New microSDHC memory cards come pre-formatted
with a FAT32 file system which is optimized for good
performance. The PDR relies on this performance and
will never disturb the underlying low level formatting
of the SD card. When the SMWB/SMDWB “formats”
a card, it performs a function similar to the Windows
“Quick Format” which deletes all files and prepares
the card for recording. The card can be read by any
standard computer but if any write, edit or deletions
are made to the card by the computer, the card must
be re-formatted with the SMWB/SMDWB to prepare it
again for recording. The SMWB/SMDWB never low level
formats a card and we strongly advise against doing so
with the computer.
To format the card with the SMWB/SMDWB, select
Format Card in the menu and press MENU/SEL on the
keypad.
WARNING: Do not perform a low level format (com-
plete format) with a computer. Doing so may render
the memory card unusable with the SMWB/SMDWB
recorder.
With a windows based computer, be sure to check the
quick format box before formatting the card.
With a Mac, choose MS-DOS (FAT).
IMPORTANT
The formatting of the SD card sets up contiguous sec-
tors for maximum efficiency in the recording process.
The file format utilizes the BEXT (Broadcast Extension)
wave format which has sufficient data space in the
header for the file information and the time code imprint.
The SD card, as formatted by the SMWB/SMDWB re-
corder, can be corrupted by any attempt to directly edit,
change, format or view the files on a computer.
The simplest way to prevent data corruption is to copy
the .wav files from the card to a computer or other Win-
dows or OS formatted media
FIRST.
Repeat – COPY
THE FILES FIRST!
Do not
rename files directly on the SD card.
Do not
attempt to edit the files directly on the SD card.
Do not
save
ANYTHING
to the SD card with a comput-
er (such as the take log, note files etc) - it is formatted
for SMWB/SMDWB recorder use only.
Do not
open the files on the SD card with any third
party program such as Wave Agent or Audacity and
permit a save. In Wave Agent, do not IMPORT - you
can OPEN and play it but do not save or Import - Wave
Agent will corrupt the file.
In short - there should be NO manipulation of the data
on the card or addition of data to the card with anything
other than an SMWB/SMDWB recorder. Copy the files
to a computer, thumb drive, hard drive, etc. that has
been formatted as a regular OS device FIRST - then
you can edit freely.
iXML HEADER SUPPORT
Recordings contain industry standard iXML chunks in
the file headers, with the most commonly used fields
filled in.
