1.5.2 Activating Test Operating Mode
To launch the Test Mode by the external key, proceed as follows:
1. From any operating mode, press the Test key: the TX Data/ACT LED turns on.
2. Keep the Test key pressed for minimum one second while the Ext Trig/RDY LED
turns on. Both LEDs hold this status if the key is not released.
3. Release the Test key. Both LEDs turn off, the Test Mode starts and the Bar
Graph is active.
If the Test key is released before Ext Trig/RDY LED turns on, the test mode is not
executed. The device holds the previous operating mode.
During the Test Mode, the Bar Graph repeatedly indicates the Good Read Rate
(GRR) every 100 scans (about 1 second). At the end of each sampling all the LEDs
turn OFF.
The test mode data are transmitted on the serial interfaces according to the current
configuration.

To exit the Test Mode, repeat the above procedure: when the TX Data/ACT and the
Ext Trig/RDY LEDs turn off the Test Mode has been disabled.
The previous operating mode will be restored.
NOTE
If the scanner has been configured in Test Mode via software, a first
Test key press will produce no effect. A second Test key press will
exit the Test Mode and enable the Default On Line mode.
