6 Fault diagnosis and elimination
There are different faults that could appear.
Not all incoming components or systems have to be faulty.
The customer could have problems with the operation of the phone or
could have placed it close to a device (PC...) that affects it.
So you won?t identify a fault.
It could also happen, that there is a loose connection in the phone
(due to a cold soldering joint or something else).
So the fault won?t appear each time you test the phone.
There are different possibilities to test a phone depending on the information
you got with the phone.
6.1 Functional Test
There is an incoming and an outgoing test.
The difference between them is that in the outgoing test you make a reset
on the component after testing in case of swap (to deregister, reset PIN and
set to factory defaults). The steps for the mobile unit refer to Gigaset 3000 Classic.
Outgoing test:
1) Displaytest 3000 Classic:
Mobile unit is switched off.
Press 1, 4 and 7 simultaneous and hold down while switching on.
Press any key to alter pattern.
2) Charging-test:
Mobile unit is switched off.
Put mobile unit into charging cradle.
One segment of the battery display has to start blinking automatically
when putting in.
3) Make a fundamental reset on the base station you want to test in case of swap:
Disconnect mains.
Press paging key on base station and hold down.
Plug in AC- adapter.
Hold key pressed for 25 seconds. Release paging key.
The base station is now set to factory defaults.
The system code is set to 0000 and all mobile units are deregistered.
4) Reset mobile unit to factory defaults in case of swap:
1, 8, OK, 0, 0, 0, 0, OK, 0, OK
