10 Data Communication Problems
•
Make a general visual inspection for corrosion or oxidation due to liquid damage. No
further action should be taken for a liquid damaged phone. Handle the unit on according
to the local company directives.
NOTE!
•
Sending data calls must be initiated from the appropriate computer program. To send data
calls you need to connect the phone to a computer via a cable and then start the computer
program.
•
To receiving data calls the phone must be connected to the computer via a cable and then
start the computer program and you must answer the call from within the computer
program (if it is not answered automatically).
If the SIM card does not support separate voice and data numbers, the phone does not
recognise the type of incoming call.
To make possible receiving data calls choose 3. Call info / 5. Next call / 1. Next
incoming /Data.
•
If no communication is accomplished with system connector, check it for dirt/mechanical
damage (Fig. 1). If necessary clean or replace the system connector.
•
Try to upgrade the phone with the latest software.
•
If the fault still remains handle the unit on according to the local company directives.
