Visual Indicators

There are a red LED and a green LED on the scanner. When the scanner is on, the flashing or stationary activity of the LEDs indicates the status of the scan and scan-ner.

No Red or Green LED

There are two reasons why the LEDs will not be illuminated:

1.) If the scanner is receiving power and the LEDs are not on, then the scanner has been dormant for a specified time and the laser has turned off. To reactivate the unit, pass an object through the scan field.

2.) If the scanner is not receiving power from the host or trans- former, then the LEDs will not be on.

Steady Red

When the laser is on, the red LED is also on. The red LED will remain on until the scanning period has expired.

Steady Red and Single Green Flash

When the scanner successfully reads a bar code, the green LED will flash then beep once. If the green LED does not flash or the scanner does not beep once, then the bar code has not been suc- cessfully read.

Steady Red and Steady Green

After a successful scan, the scanner transmits the data to the host device. If the host is not ready to accept the information, the scan- ner’s green LED will remain on until the data can be transmitted. The red LED will turn off when the scanning period expires.

Steady Red and Flashing Green

This indicates the scanner is in program mode. A razzberry tone indicates that an invalid bar code has been scanned in this mode.

Steady Green

This indicates the scanner may be waiting for communication from the host.

Flashing Green

This indicates the scanner is waking up from a dormant state in response to an IR sensor activation. Refer to page 18.
