2 Procedures
Hidden service procedures for the handset and base stations.
Note: The service procedures are confidential.
2.1 Service procedures for Gigaset E45 handset
Read out IPUI of the handset (for identification purposes): menu-key, *, #, 0, 6, #
Press 1, 4 and 7 simultaneously and keep keys pressed
Switch on and keep key pressed until "SERVICE" is visible, then release
all keys
Press 4685463 (HOTLINE
This code performs a fundamental reset on
the handset. All settings are reset to factory
defaults. Handset is still registered to base.
Service-menu is displayed with following items:
SW-version, QS-data, Speechpath test, Battery
mode, DSP-parameters, Metering mode,
Measure time, Working time, SAR.
Red items are only for Development Department
or Quality Assurance and not explained here!
SW-version:
Read out SW-version and IPUI (international portabl e user identity) of
handset. IPUI is a unique number (like IMEI) that could be used for identification.
Speechpath-test:
Switches a direct loop between microphone and loudspeaker.
This enables a check of the speechpath by blowing in the microphone.
Metering mode:
Press o.k. to activate an information line during normal operation
mode and leave the service menu afterwards.
Example: 100 - 0 - 02 - 016 - 100
RX-level - Frequency - Time slot - Base code - Bit error rate (100 = 100% o.k.)
Measure time:
Changes the measure time of the metering mode (change is not
necessary).
Working time:
Read out the time for which the handset has been switched on.
Example: 100h means handset has been switched on for 100 hours.
It can only be reset at WSC.

(dependant on country)
Time for end of call identification
(to distinguish between 2 ringing pulses of
one call with long pauses between pulses
and 2 separat e calls)
Hook-flash-prevention (cradle switch
identification) (short press on cradle switchkey is extended by SW to prevent that it is
interpreted as a press on the flash-key)
Pause after line seizure
Music on hold
Suppress first call if SMS is activated
Switch SMS functionality
System PIN reset
Programming data on an address
Read out SW-version
(decimal figures)

** Working time
Read out the time for which the base station has been switched on.
Example: 100h means the base station has been switched on for 100 hours.
It can only be reset at WSC.
Service Settings:
Read out service settings of the base station via handset during an external call
(Hotline feature).
Preconditions:
Line seized, number dialled and connection is established for at least 8 seconds.
Press softkey “options”, select “service info” and confirm with “o.k.”.

Fundamental reset:
Disconnect mains. Press paging key on base station and hold down.
Plug in AC- adapter. Hold key pressed for more than 3 seconds.
Release paging key. The base station is now set to factory defaults.
The system-PIN is reset to 0000 and all mobile units are deregistered.
If a handset was registered only to this base station before the reset, it can be
registered automatically after a location update with the base station (after appr.
30 seconds or after picking up the handset (off hook key).

4 Test setup recommendation
- Gigaset 4170 or 4175 to be used as a PBX
- Gigaset handset (with charger) which is registered on Gigaset 4175
- Gigaset E450 base station to test customer‘s handset
- Gigaset E45 handset to test customer‘s base station
- 2 multimeters:
- 1 voltmeter to measure the PSTN line voltage of the customer‘s base
- 1 amperemeter to measure the AC-current of the AC-adaptor connected
to the customers base station
- 2 modified cables:
- 1 AC adaptor where the cable is opened (cut off) for the amperemeter
- 1 Mini-Western PSTN cable with a parallel cable for the voltmeter
See next page for the setup.

4.1 Test steps handset
- Try to verify the customer‘s fault description. If necessary perform a
long term test (sporadic problems (e.g. RF) or charging problems).
- Complete test (e.g. if no customer‘s fault description available)
- Switch the customer‘s handset on.
- Check function of display.
- Register handset on golden device base station.
- Set up an external call to the test handset that is registered to the G4175.
- Do an audio test in transmit and receive direction (speech).
- Check if the handset switches on hook when putting it in the charger.
- Control the charging current with the help of the customer‘s base station or
use the appropriate golden device base station / charger.
Current consumption in charger is appr. 160-170 mA. If a base is used for test:
Add the normal current consumption of the base station to the charge current.
- Do a ringer test on customer‘s handset by receiving an incoming call.
- Test the RF-range of the customer‘s handset by walking to a marked line.
4.2 Test steps base station
- Try to verify the customer‘s fault description. If necessary perform a
long term test (sporadic problems (e.g. RF) or charging problems).
- Complete test (e.g. if no customer‘s fault description available)
- Check the current consumption of the customer‘s base station.
- Control the PSTN voltage.
- Register golden device handset on customer‘s base station.
- Pick up the handset and check the PSTN voltage.
- Set up an external call to the test handset that is registered to the G4175.
- Do an audio test in transmit and receive direction (speech).
- Control the charging current with the help of a golden device handset.
Charge current consumption appr. 160-170 mA.
Add the normal current consumption of the base station to the charge current.
- Do a ringer test on customer‘s base station by receiving an incoming call.
- AM base stations: Test the function of the answering machine by leaving
a message on the AM. Check the quality of the message afterwards.
- Test the RF-range of the customer‘s handset by walking to a marked line.
Do a fundamental reset on the handset / base station in case of swap.
