to newspapers which are structured by folders. These structures are usually generated
electronically and an “AUTONEXT.YES” file may as well be generated automatically for each
folder.

Navigation
Navigation within a hierarchical level is achieved with the “FF” and “Rew” buttons. The
“Rec” and “Mode” buttons are used to navigate from one hierarchical level to another
hierarchical level.
6.3.1.
Navigation within a hierarchical level
“FF”/”Rew” are used to select the next/previous file or the next/previous folder. With the
“Rew” button you jump to the start of the current message. If you press the “Rew” button
before the message has already played for more than three second then the push of the
button will take you to the start of the previous message.
To reach the first recorded message in a folder or to reach the first subfolder within a folder,
press and hold down the left arrow button while simultaneously and quickly pressing the
“Play” button. The last recorded message/last subfolder is reached in a similar manner by
pressing and holding down the right arrow button and briefly pressing the “Play” button.
To quickly navigate within a long message, keep the left or right arrow button pressed
constantly. Scrolling as known from CD players will start after approximately one second.
The scrolling speed will increase over time from about triple speed to a maximum speed
which is about twenty-fold. Letting go of the arrow button will resume playback at regular
speed.
6.3.2.
Navigation from one hierarchical level to another hierarchical level
To enter a folder you need to press the “Mode” button while being positioned on the folder.
You will know that you are positioned on a folder because the message “Folder…” will play
as you navigate onto the folder. Pressing the “Mode” button while not being positioned on a
folder will trigger a beep. Pressing of the “Play” button will either enter a folder or replay the
next available MP3 file.
Pressing of “Rec” will always take the user up one hierarchical level if such a level exists. If
the user is already on the highest level another beep will sound.
Change of a hierarchical level is announced with the sound sequence “high pitched-low
pitched” when descending and “low pitched-high pitched” when ascending.
Folder names are announced with „Folder...“. If the folder has been voice labelled then the
recorded folder name will be played. If no voice labelling exists the folder will be announced
with the number that corresponds to position of the folder within the current folder. Example:
the fourth folder will be announced with “Folder 4”. Numbering continues only up to folder
10. If additional folders exist then they will only be announced with “Folder”. File names are
not announced acoustically.
