1.3 LED INDICATOR
The dual-color LED on top of the scanner is used to provide user feedback. For example,
the LED becomes solid red and goes off quickly (= Standby mode) upon powering on or
running out of transmit buffer. You may tell the difference by the beeps – for example,
you will hear a long beep of high tone when powering on the scanner, and a long beep of
low tone when the transmit buffer becomes full.
