30Chapter 8 Beeper, Indicator LED, Vibrator and Marker Beam8.1 Beeper(1) BeepingThe scanner emits a short or long beep as described below.The beeper emits a short beep when:- the scanner has read a code successfully,- code data read matches the master data in the Data Verification mode,- the scanner has read a split QR code,- data transfer is started by the data retransfer function or specific character transfer function,- readable codes are switched by the readable code switching function, or- the "Start setting" or "End setting" code is read (3 beeps) or the parameter setting QR codes are read (1 beep) from theQR-coded parameter menu (given in Chapter 12).The beeper emits a long beep when:- a scanning error has occurred at the scanner,- code data read does not match the master data in the Data Verification mode,- the scanner has read split QR codes in the Edit mode to the point that the accumulated data exceeds 8 kilobytes,- a master code has the wrong number of digits during registration of master data,- a code other than a parameter setting code is read during parameter setting by the QR-coded parameter menu,- a transmission error or timeout occurred when the scanner was communicating with the configuration software,- a communications error has occurred,- an invalid control command is received, or- the previously sent data is not available at the time of data retransfer (using the magic key).You can disable the beeper using the QR-coded parameter menu or configuration software. In any of the following cases,however, the beeper sounds regardless of that beeper setting:- when you make settings by scanning the QR-coded parameter menu,- when the scanner receives a beeper-ON command from the host PC,- when the configuration software starts up or any setting you have made is established,- when the scanner reads a batch-process QR code, and- when the parameter values are saved by a PW command (refer to Appendix 2).(2) Adjusting the beeper volumeYou can adjust the beeper volume to three levels--high, medium and low--using the QR-coded parameter menu orconfiguration software. The factory default is High.Each time the beeper volume adjustment QR code is read, the beeper volume cycles as shown below.Even if the scanner is turned off, this setting will be preserved.High Medium Low
