NOTICE
Configured PIN and PIN on the SIM card must match.
If you enter the PIN of the SIM card of the CP 1242-7 incorrectly during STEP 7
configuration and download the station, the CP stores the wrong PIN. An incorrectly
entered PIN is transferred by the CP only once so that the SIM card is not locked.
If you change the PIN of the SIM card externally to the incorrectly configured PIN (new
PIN of the SIM card = incorrectly entered PIN in STEP 7), the CP rejects this PIN again
without checking it.
Solution after entering an incorrect PIN:
To avoid the PIN being rejected by the CP again, use a PIN that is different from the
incorrectly entered PIN. Procedure:
 If the PIN of the SIM card was not changed:
– Configure the PIN in STEP 7 with the PIN of the SIM card.
– Reload the station.
 If the original PIN of the SIM card was changed externally to the PIN that was
previously incorrectly entered in STEP 7:
– Change the PIN of the SIM card externally to a new PIN that has not yet been
incorrectly configured in STEP 7.
– Change the configured PIN in STEP 7 to the newly assigned PIN of the SIM card.
– Reload the station.
