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 upon powering on or running out of
transmit buffer. Tell the difference by the beeps – for example, it 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.
