Switch-on characteristics
The Universal Portable CTEL Interface (UPCI) system is activated using the On/Off button on the portable CTEL (A34/6). Automatic activation is possible by means of a wake-up pulse via the Media Oriented System Transport (MOST).
It can be initiated via the status "Circuit 15 ON", the radio (A2), the radio control panel and navigation unit (A2/56) or the COMAND operating, display and controller unit (A40/3).
Before the Universal Portable CTEL Interface (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.
If the number is entered wrongly 3 times, the SIM card is barred and has to be released using the personal 8-digit Personal Unblocking Key (PUK). This allows entry of 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 Universal Portable CTEL Interface (UPCI) system is deactivated using the On/Off button on the portable CTEL (A34/6) or automatically after the after-run time set on the portable CTEL (A34/6).
The portable CTEL (A34/6) is decommissioned by operating the On/Off button on the respective portable CTEL (A34/6) and removing the SIM card.

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