NB* To test the PCB on its own without a housing or SIM card the unit must first be put into test mode
and then into Tx or Rx mode using the applicable manual test commands. Ensure that a battery is
present during this, as the battery acts as a SIM card presence detect for the unit. The PCB can then be
taken out of the housing for any analysis.

6.7 Testing IrDA Port

To test the IrDA port the following set up should be followed, the distance between handset and IrDA
port should be less than 30cm and although accurate alignment is not neccesary the two should be lined
up as well as possible.
Note. Software is required for both the P7382i / P7389i IrDA link and also the host IrDA port.
A CD Rom will be shipped with the unit to enable data transfer, the drivers for the host IrDA device
should be supplied with the device. For testing all we are looking for is the discovery frame between
PC and handset.
