SPDR Power
Battery Installation
The audio recorder is powered by two AA Quantum (recommended) or Lithium
batteries.
Push outward on the battery compartment door and lift it to open.
Insert the batteries according to the markings on the backside of the housing.
Power Input Connector
The SPDR is designed to be used with the CH12 external (or equivalent)
power source. The nominal voltage to operate the unit is 12 VDC, although it
will operate at voltages as low as 6 VDC and as high as 17 VDC. External power
sources must be able to supply 200 mA continuously.
NOTE: There is an automatic switch over to internal batteries if power is
interrupted.
microSDHC memory card
Insert the card with the contacts facing the control panel side of the recorder.
Formatting the 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 PDR “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 PDR to prepare it again for recording. The PDR never low-level formats a card and we strongly advise against doing so with the computer.
To format the card with the PDR, select Format Card in the menu and press MENU/SEL on the keypad.
NOTE: An error message will appear if samples are lost due to a poor- performing “slow” card.
WARNING: Do not perform a low-level format (complete format) with a computer. Doing so may render the memory card unusable with the PDR 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) if the card is 32 GB or smaller, exFAT if the card is 64 GB or larger.
IMPORTANT
The formatting of the PDR SD card sets up contiguous sectors 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 PDR, 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 Windows or OS formatted media FIRST. Repeat __ – COPY THE FILES FIR_STI
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 computer (such as the take log, note files, etc) – it is formatted for PDR use only.
Do not open the files on the SD card with any third-party program such as Wave Agent or Audac
