Audible Indicators
When the IS220 is in operation, it provides audible feedback. These sounds indicate the status of the scan
engine.
One Beep
The scan engine will beep once when it first receives power, the red LED will flash and the scanner will
beep once. The red LED will remain on for the duration of the beep. The scan engine is ready to scan.
When the scanner successfully reads a bar code, the red LED will flash and the scanner beeps once (if
configured to do so). If the LED does not flash, then the bar code has not been successfully read.
Razzberry Tone
This is a failure indicator. Refer to Failure Indicators on the next page.
Two Beeps - On Power Up
When a Flash ROM upgrade is needed, the scanner will beep twice followed by alternating flashes of the
red and green LEDs.
Three Beeps - During Operation
When the scan engine enters configuration mode, the red LED will flash and the unit will simultaneously
beep three times. The green and red LEDs will continue to flash while in configuration mode. Upon exiting
configuration mode the scanner will beep three times and the LEDs will stop flashing.
When configured, three beeps can also indicate a communications timeout during normal scanning mode.
When using one-code programming, the scanner will beep three times (in the current selected tone),
followed by a short pause then by a high tone and a low tone. This indicates the single configuration bar
code has successfully configured the scan engine.
