SD Card Lock
The LOCK switch on the SD card can be used to protect an announcement from
accidental erasure. When the LOCK switch is in the ON position, the DL4 will not allow
the user to record a new announcement. The unit will play back normally with the LOCK
switch ON.
Life of SD Card
All SD memory cards have a maximum number of times that you can write to them. In
general most cards have approximately a 100,000 write cycle life. There is no limit on the
number of times that you read the data. The DL-4 will display a message indicating that
the card is bad when it is worn out.
Audio WAV File
The DL-4 uses a specific WAV file format that is compatible with Windows based
computers. This makes it possible for the end user to produce and/or store audio files
directly on their computer. The specifications for the WAV file format is as follows:
