Digital Hybrid Wireless Belt-Pack Transmitters

IR (infrared) Sync
The IR port is for quick setup using a receiver with this
function available. IR Sync will transfer the settings for
frequency, step size and compatibility mode from the
receiver to the transmitter. This process is initiated by
the receiver. When the sync function is chosen on the
receiver, hold the IR port of the transmitter near the IR
port of the receiver. (There is no menu item available on
the transmitter to initiate the sync.)
NOTE: If a mismatch exists between the receiver and
transmitter, an error message will appear on the transmitter LCD
stating what the problem is.
Battery Installation
The transmitter is powered by AA batteries. We recom-
mend using lithium for longest life.
Because some batteries run down quite abruptly, us-
ing the Power LED to verify battery status will not be
reliable. However, it is possible to track battery status
using the battery timer function available in Lectroson-
ics 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 22.
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
your dealer or 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.
Connecting the Signal
Source
Microphones, line level audio sources, and instruments
can be used with the transmitter. Refer to the section
entitled Input Jack Wiring for Different Sources for
details on the correct wiring for line level sources and
microphones to take full advantage of the Servo Bias
circuitry.
Formatting SD Card
New microSDHC memory cards come pre-formatted
with a FAT32 file system which is optimized for good
performance. The unit relies on this performance and
will never disturb the underlying low level formatting of
the SD card. When the DBSM/DBSMD “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 DBSM/DBSMD to prepare it again for record-
ing. The DBSM/DBSMD never low level formats a
card and we strongly advise against doing so with the
computer.
To format the card with the DBSM/DBSMD, 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 DBSM/DBSMD record-
er. 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 DBSM/DBSMD 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 DBSM 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 DBSM/DBSMD 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.
