Notes
- Once registered, audio data files can no longer be erased, so overwrite them with new ones.
- Audio data files out of the specifications cannot be registered.
(2) Playing back an audio data file
Using the configuration software (ScannerSetting_2D) or control commands (IS and VOLSND in Appendix 2) to be
sent from the host plays back audio data files previously registered.
Notes
- During playback of an audio data file, no code can be read.
- If the playback time of an audio data file is long, take it into consideration in system operation.
- Playback specified by a control command has priority over that by the configuration software (ScannerSetting_2D).
If the scanner receives two or more playback commands, the last one takes effect.
(3) Adjusting the playback volume
You can adjust the playback volume to ten levels for each audio data file, using the QR-coded parameter menu,
configuration software (ScannerSetting_2D), or control commands.
Notes
Depending upon the playback volume selected, the speaker may make crackling or stuttering sounds due to the
installation environment.
