Cale CWT Compact: Troubleshooting Voice Prompt... | terminalfaults.org

Technical Background:

The CWT Compact utilizes a text-to-speech (TTS) engine controlled via software parameters. The audio output is generated by a dedicated sound card with a 24V DC amplifier. Configuration settings controlling voice prompts are typically stored in non-volatile memory and are accessed through the system's configuration interface. Improper configuration or corruption of configuration files can lead to the persistence of voice prompts. External factors, such as fluctuating power levels, can disrupt the configuration process.

Symptoms:

Voice prompts are active on the Cale CWT Compact and need to be temporarily disabled for accessibility testing purposes.

Possible Causes:

Incorrect configuration settings within the CWT Compact's software.
Corrupted configuration file due to power interruption during configuration.
Firmware malfunction causing the system to default to voice prompts.
Accessibility settings were unintentionally enabled or re-enabled after a software update.
Hardware failure of the sound card or amplifier (unlikely, but possible if prompts are distorted or absent altogether after attempts to disable).
Software bug that forces voice prompts on

Solution:

1

Access the CWT Compact's configuration menu. This usually involves a specific key sequence or administrator login.
2

Navigate to the 'Accessibility' or 'Audio' settings within the configuration menu.
3

Locate the option to disable voice prompts or text-to-speech functionality.
4

If a specific 'Voice Volume' control exists, reduce it to zero.
5

Save the changes to the configuration. The CWT Compact may require a reboot for the changes to take effect.
6

Verify that the voice prompts are no longer active after the system restarts.
7

If prompts persist, consult the Cale CWT Compact's technical manual for specific instructions on disabling voice prompts, or contact Cale support.

Safety Warning:

This device operates on 24V DC. While this voltage level is generally considered safe, ensure that all connections are secure and that the power supply is properly grounded. When performing any maintenance or configuration changes, disconnect the power supply. This device is located in a public area, which may expose the operator to risk of vandalism or environmental hazards. Always be aware of your surroundings and take necessary precautions.

Prevention:

To prevent accidental re-enabling of voice prompts, document the steps required to disable them. Perform regular backups of the CWT Compact's configuration to facilitate quick restoration in case of corruption. Ensure a stable power supply to the kiosk to prevent data corruption during configuration changes. Implement user access controls to limit modifications to accessibility settings.

Expert Tip:

If the standard configuration menu does not offer an option to disable voice prompts, attempt accessing the 'engineering mode' or 'service menu'. This mode often contains more granular control over system settings. Consult the Cale CWT Compact's service manual for instructions on accessing this mode. If the unit supports remote access via a network, verify if the voice prompt settings can be managed remotely via the Cale central management system.
