Battery Condition and Player Statistics

The player saves usage statistics in its non-volatile memory that can be recovered and saved.
Preconditions:
(for steps 4-7 only)
1. No DTB cartridge is inserted in the player.
2. An USB flash drive is inserted in the USB AT device port.
Methodology:
Battery charge statistics are reported as an audio message using a diagnostic operation.
A diagnostic function is used to transfer accumulated player statistics to a USB flash drive.
The player collects gross statistics on the usage of various systems (e.g., the number of hours that the player has
been used on battery power and on AC power, number of charge cycles, etc.). These data will be used by NLS to
better tailor the next version of the player to the needs of the patron.
No personal information is obtained in this procedure nor is any information obtained that identifies the
books read.
NLS requests that cooperating agencies obtain these data when players are returned from patrons and send them
to NLS engineering (NLSplayerdata@loc.gov). The data exported from the player take the form of a file with the
player's serial number as part of the file name. A library should accumulate many such files and at convenient
intervals (3 to 6 months) send them together as one or more zip compressed files.
