GF82.70-D-2007H Switch Telephone On/Off Characteristics, Function

- with CODE (EH3) Universal preinstallation for networked portable CTEL

Switch-on characteristics
The Universal Portable CTEL Interface (UPCI) system is activated after one of the following actions:
- By pressing the On/Off button of the respective portable CTEL.
- Automatically by a wake-up pulse via the Media Oriented System Transport (MOST), which is initiated by the radio/radio with navigation (N87/1) with code (EF9) Sound 20 radio, the radio/radio with navigation with code (EN4) COMAND with TMC interface or the radio/radio with navigation with code (EN8) Sound 50 APS radio.
- Activation of "circuit 15R ON" status.

Before the Universal Portable CTEL Interface system can be started up, it must be logged into the respective telephone network. The Subscriber Identification Module (SIM) on the SIM card is needed to do this. After inserting and activating the SIM card the user must enter the 4 to 8-digit Personal Identification Number (PIN) when requested to do so.
This PIN prevents unauthorized use of the SIM card and therefore protects against misuse.
The SIM card is locked after 3 incorrect entries. The Personal Unblocking Key (PUK), an 8-digit number code, can be used to deactivate the access prevention. This allows entry of a new PIN number. If the PUK is entered wrongly 10 times in succession, the SIM card can no longer be used and a new SIM card must be applied for from the service provider. If the PIN is entered correctly, the corresponding portable CTEL logs into the respective service provider network and is ready for use.

Switch-off characteristics
The UPCI system is deactivated by one of the following actions:
- By pressing the On/Off button of the respective portable CTEL
- Automatically after the individually adjustable run-on time of the respective portable CTEL
- After removing the transmitter key (A8/1) and following expiry of the individually adjustable run-on time of the respective portable CTEL

Switching off system
The respective portable CTEL is decommissioned by pressing the On/Off button on the respective portable CTEL and then removing the SIM card.

The SIM card may only be removed once the respective portable CTEL has been switched off in order to protect the SIM on the SIM card from destruction. When the respective portable CTEL is switched on again, the PIN has to be reentered.
