Chapter 8 Beeper, Indicator LED

8.1 Beeper

(1) Beeping
The scanner emits a short or long beeps, once or a couple of times as described below.
（Refer to Section 8.3 for details of beeper in various states）
You can disable the beeper using the Bar coded parameter menu or configuration software (ScannerSetting).
In any of the following cases, however, the beeper sounds regardless of that beeper setting:
- when you make settings by reading the Bar coded parameter menu,
- when the scanner receives a beeper-ON command from the host computer,
- when the configuration software (Scanner Setting) starts up or any setting you have made is established,
- when the scanner reads a batch-process QR Code symbol,
- when the parameter values are saved by a PW command (refer to Appendix 2), and
- when the beeper is enabled at power ON.
(2) Adjusting the beeper volume
You can adjust the beeper volume to three levels--high, medium and low--using the Bar coded parameter menu
or configuration software (Scanner Setting). The factory default is High.
Each time the "Beeper volume" Barcode symbol is read, the beeper volume cycles as shown below.
Even if the scanner is turned off, this setting will be retained.
At the shipment, the beeper volume is set at "High".
(3) Adjusting the beeper frequency (tone)
The following three choices are available for beeper frequency (tone) using the barcode menu or configuration
software (Scanner Setting).
