Installing / Removing the Reader 4–2

On initial power-up, the Reader performs a series of self-diagnostic

tests and LED tests (all LEDs flash). When the Module LED flashes

and turns a steady green the power-up sequence is complete. The

complete power-up sequence takes a few seconds.

The Reader is shipped from the factory with these defaults:

• All symbologies enabled (except Pharma Code).

• Laser Light set to Always On in Scanner dialog.

If the initial Reader configuration has been changed, you must

enable the Code 39 symbology and the other parameters above.

(Refer to the AdaptaScan Software user manual.)

To quickly check the operation of a Reader with factory defaults:

1. Apply power to the Reader.

2. Position the above Code 39 test symbol approximately 12 inches

(.3 meter) from the Reader. Skew the page slightly.

slightly skewed.

3. The scan beam should be scanning continuously.

4. Observe the Symbol LED. The Symbol LED illuminates when

the Reader is scanning the bar code symbol.
