This parameter allows you to select how audio feedback from the scanner is projected. There are two options
Internal speaker – In-built speaker provides audio output that can be configured up to 3 different levels (Refer to Beeper Volume). Barcode “Internal speaker 1” can be used to reset to this default setting.
External speaker – Enables an auxiliary speaker, if one is needed and connected. Barcode “External speaker 0” will activate this functionality.
Auxiliary cables and speakers are to be user supplied. This parameter can only be used to alternate between internal and external speakers, both will not function simultaneously.
