WLAN functional tests

On/Off test
Prerequisites
A flash adapter connected to a PC with Phoenix service software is required.
From the testing toolbar select WLAN Configuration option. This opens the WLAN configuration dialogue
box below. Selecting the Power state option button (as indicated), the WLAN can be turned ON and OFF:
1 With Power State set to OFF, measure the dc power supply current consumption of the flash adaptor.
2 Next return the Power state to ON and re-measure the dc power supply current of the flash adaptor.
The difference between the currents in (1) and (2) should be between 190 to 220mA. When WLAN is ON, the
firmware has been downloaded and the WLAN module is in the receive state. When OFF WLAN is powered
down.
