A difference to G3000 systems is that the handset has to be registered to the base station by the customer. Therefore the customer has to insert the handset in the base station and wait until the handset is regsitered. A handset that has been registered on another base station has to be registered manually (similar to G3000). Therefore a paging key is existing under the base station.

3 Procedures

This chapter shows the hidden service procedures for Gigaset 4000 Classic, 4000 Comfort and 4010 base stations.
Note: The service procedures are confidential.

3.1 Service procedures for Gigaset 4000 Classic

Reset to factory defaults (customer procedure):
This procedure resets the handset to factory defaults. Press softkey "menu", 9 3 and confirm with o.k. (see user guide).
Displaytest:
Press 1, 4 and 7 simultaneously and hold down while you switch on. Press any key to toggle between the displayed signs. Afterwards switch handset off.
To get into the service procedures you need to press 1,4 and 7 simultaneous and hold down while you switch on, afterwards press 76200.
1. SW-Version and IPUI:
On the left upper corner the number of the menu is shown (here menu 1). At first the SW-version is displayed. The digits above the 2. arrow show the version (e.g. 16). When scrolling down with the "arrow down key" the IPUI number is displayed. The I on the left side indicates that this is the IPUI.
2. QS data:
This data is only important for the production, not for service purposes.
3. Speechpath-test:
You can select this item when you want to check the speechpath by blowing into the microphone and checking this noise on the earphone (without beeing registered to a base station).

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 received 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).
Outgoing test (system):
1) Displaytest 4000 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) There are 2 possibilities of testing the fundamental functions of the telephone:
1) Test with PBX (private branch exchange): a) Ringer test (not for Comfort base stations) b) Dialling test c) Audible test of telephone in transmit and receive direction (speech)
with the help of a second phone 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)
- Audible test of telephone in transmit direction (SLR)
- Audible test of telephone in receive direction (RLR)
4) Make a fundamental reset on the base station you want to test in case of swap: Disconnect mains. Press paging key under the 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.
5) Reset handset to factory defaults in case of swap:
Incoming test: only step 1 to 3

6.2 Recognition of typical customer problems

This chapter shows the incoming department which fault code refers to which problem and which component is faulty. Some problems concerning the mobile unit (not possible to switch on; not possible to register; acoustic problems; charging problems ...) could be caused by humidity. So you will have to open the mobile unit (opening tool) and look for tracks of a humidity damage. Many problems concerning the base station could be caused by lightning stroke. So you will have to open the base station and look for tracks of a lightning stroke.
Problem 1: The customer can‘t hear the other subscriber during a call (or hears his speach at a low volume). When he blows into the microphone he can‘t hear his noises on the earpiece. Fault code: D 20 (RLR) Faulty component: Mobile unit
When he blows into the microphone he can hear his noises on the earpiece. Fault code: D 20 (RLR) Faulty component: Base station
Problem 2: Other subscribers can‘t hear the customer during a call (or hear his speach at a low volume).
When he blows into the microphone he can‘t hear his noises on the earpiece. Fault code: D 19 (SLR) Faulty component: Mobile unit
When he blows into the microphone he can hear his noises on the earpiece. Fault code: D 19 (SLR) Faulty component: Base station
Problem 3: The customer can‘t switch on his mobile unit. Check the batteries and insert new ones for testing.
Fault code: D 26 (no function)
Faulty component: Mobile unit
