Model 171.4 with CODE (388) Telephone "Portable CTEL", UPCI system 

Model 171.4 with CODE (494) USA version 

ON/off characteristics 

The Universal Portable CTEL Interface (UPCI [UHI]) system is manually activated using the on/off button on the portable CTEL (A34/6) or the activation takes place automatically when circuit 15 is activated via the Media Oriented System Transport (MOST) by means of a wake-up pulse by one of the following audio sources:

• Radio (A2), with code (523) MB Audio 20 radio
• Radio and navigation unit (A2/56), with code (525) MB Audio 50 APS radio
• COMAND operating, display and control unit (A40/3), with code (527) COMAND APS with single DVD drive (with navigation) or with code (530) COMAND APS USA (with navigation system)

Before the UPCI system can be started up, it must be logged into the respective telephone network (e.g., D-net or E-net). 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. After 3 incorrect entries, the SIM card is blocked and has to be enabled with the aid of the personal 8-digit Personal Unblocking Key (PUK), which makes it possible to enter a new PIN.

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 portable CTEL (A34/6) logs into the respective service provider network and is ready for use.

Switch-off characteristics 

The UPCI system is manually deactivated using the on/off button on the portable CTEL (A34/6), or the deactivation takes place automatically after the run-on time that can be set individually on the portable CTEL (A34/6). The portable CTEL (A34/6) is decommissioned by operating the on/off button on the portable CTEL (A34/6) and removing the SIM card.

The SIM card must only be removed if the portable CTEL (A34/6) has been switched off in order to protect the SIM on the SIM card from destruction. When the portable CTEL (A34/6) is switched on again, the PIN has to be reentered.
