Buttons on the bar code scanner housing
There are two yellow buttons on the bar code scanner housing in the LED area (see
chapter 4.1.1 Device view, page 24
). You can call up predefined functions via these but-
tons.
After changing to the button operating mode you can select one function each by repeatedly
pressing the lower button. By pressing the upper button, you can start or stop the selected
function. The "TeachIn" function (for matchcode) and "Auto-Setup" stop the bar code scan-
ner automatically. Currently you cannot call up user-defined functions.
The selected function is shown via the corresponding LED below the buttons.
When using both of the buttons the LEDs have different meanings than in normal reading operation:

Meaning of the LEDs during activation of buttons
Important
When using the buttons, the "Laser" LED's function differs from its original function in read-
ing operation, the display of the switched-on laser diode.
Use of the buttons
In order to use one of the possible function with the buttons, do as follows:
1. Press the upper button for approx. 3 seconds.
The bar code scanner stops the current reading operation, switches off the LEDs and
the bargraph display and changes to the button operating mode. With immediate effect
the bar code scanner ignores all the other external reading pulses. No reading results
are displayed via the host interface.
The beeper confirms this process with an ascending melody.
The "Read Diagn" function is pre-selected as first function (LED flashes slowly).
2. Repeatedly press the lower button until the LED of the required function flashes. The
bar code scanner scans all the possible functions successively without starting them
and starts over.
The beeper confirms each step with a sound.
3. Press the upper button once to start the selected function.
The LED flashes faster and the beeper confirms the start with two sounds.
