Illumination
The EM27 has four white LEDs for supplementary lighting, making it possible to scan barcodes even in complete darkness.
The illumination can be programmed On or Off.
Buzzer
The EM27 provides a buzzer to indicate power-on and good read statuses. The Power On Beep and Good Read Beep can
be programmed On or Off, and the Good Read Beep Volume, Duration and Frequency are also programmable by the user.
To learn how to program these parameters, please see the EM27 user guide.
Note:
It is recommended to use an external beeper to indicate good read statuses in a noisy environment.
