Resolution / Answer
This setting controls the device's sound, lighting, aiming, or image-related feedback. It is usually used when you need to reduce the beep sound, confirm the scanning status, improve lighting positioning, or adjust the image reading effect.
Due to differences in keyboard layouts, some characters contained in barcode data may not be available on the selected keyboard. Therefore, the scanner cannot transmit unknown characters. Scan the appropriate barcode below to enable or disable beeping when unknown characters are detected.
**[Close]
Scan the following barcode to configure **[Close].
[Open]
Scan the following barcode to [Open].
Assume that the corresponding language of the current scanner virtual keyboard format is French (numbered 7), and use this scanner to read the barcode with the content "AÐF". Since one character "Ð" (0xD0) in the barcode data is not among all available keys of the French keyboard, the scanner will skip this unknown character and continue processing the next character during transmission.
From the perspective of actual use, if the unknown character prompt sound is set to "off", the scanner will not have any sound prompt when transmitting, and the data transmitted to the data receiving host will be "AF";
If the unknown character beep is set to "On", the scanner will emit an error beep when processing this character, and the data transmitted to the data receiving host will still be "AF".
If the "Keyboard Simulation Input Characters" function is turned on, this function is invalid.
