Functional Test - Siemens gigaset C350 Repair Manual

4.5 Functional Test

There is an incoming and an outgoing test.
The difference between them is that in the outgoing test you do a reset
on the component after testing in case of swap (to deregister, reset PIN and set to
factory defaults). For personalized repair outgoing test is the same as incoming test.
Outgoing test (system):
1) Displaytest:
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/ base station.
One segment of the battery display has to start blinking automatically
when putting in.
3) There are 2 possibilities of testing the fundamental functions of the telephone:
1) Test with PBX (private branch exchange):
a) Ringer test handset and base station
b) Dialling test
c) Audio test in transmit and receive direction (speech)
with the help of a second phone (corded) connected to the PBX.
2) Test with telephone tester, if existing (e.g. WPG 1000):
- Ringer test (not for Comfort base stations)
- DC resistance and isolation resistance (only for base station test)
- Testing the dial information (only for base station test)
- Testing the flash hookswitch (signal key) (only for base station test)
- Audio test of telephone in transmit direction (SLR)
- Audio test of telephone in receive direction (RLR)
4) Do a fundamental reset on the base station you want to test in case of swap:
Disconnect mains.
Press paging key and hold down.
Plug in AC- adapter.
Hold key pressed for appr. 3 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.
5) Reset handset to factory defaults in case of swap:
Switch off the handset, press 1, 4 and 7 simultaneously and keep pressed while
switching on. Press 4685463 (HOTLINE).
This resets the handset completely. It is still registered to the base station.
