What do the additional signs on the pocket memo digital dictation recorder (DPM) INFO3 screen stand for?

To signify the status of various features on the pocket memo digital dictation recorder (DPM), the device employs specific indicators displayed on the INFO3 screen. These indicators help users quickly understand which functionalities are currently activated or deactivated, ensuring a seamless user experience.

One such indicator is labeled "App," which signifies that the append mode is currently enabled. When this mode is active, users can add new recordings to the end of existing files, rather than creating entirely new files. This is particularly useful for those who wish to maintain a continuous flow of audio without the interruptions that come from starting new recordings.

Another important indicator is "Lock x," where 'x' represents a specific number of minutes. This feature indicates that a PIN or PUK code has been set. After a designated period of inactivity, the DPM will prompt the user for this code to ensure that unauthorized individuals cannot access the recordings. This is a valuable security measure, especially for sensitive or confidential audio files.

The letter "A" on the screen denotes that the device is set to display the author keyword instead of the file name. This feature can be particularly beneficial in environments where multiple users are recording, as it allows for easy identification of who created each file without needing to delve into the file details.

When the letter "M" appears, it indicates that Acoustic Feedback, often referred to as "Monkey mode," is enabled. This feature provides users with auditory feedback during recording, which can assist in ensuring that the device is capturing audio as intended. It can be especially helpful for those who may not be able to visually monitor the recording process.

The letter "a" signifies that the DPM will not identify itself as a USB audio device when connected to a PC. This feature is primarily relevant for users utilizing the Software Development Kit (SDK), allowing for a more controlled interaction with the device when it is connected to a computer.

Lastly, the indicator "c" informs users that the DPM will not charge its batteries through the USB connection. Instead, charging can only occur via an AC adapter. This limitation is also applicable to SDK users and is essential for managing power effectively while ensuring the device remains functional during use.
