request (double beep repeated with no pause).

port:
1. Hook off the phone, you hear the PUK code request tone (double beep with no pause).
2. Enter the PUK code using the phone keypad (using a DTMF phone) and confirm by pressing
the “#” (hash) button, followed by a new PIN code with 4 digits, then press “#” again.

4. If the PUK code is correct you will hear the configuration tone (continuous tone repeated
twice).

ROAMING CALLS
In factory configuration the GSM/PSTN interface detects automatically the GSM operator. If the
device is installed near the State boundaries, it could detects the foreign GSM operator, and the
tariff could be higher during the voice conversations.
To advise the user of this particular situation, if in roaming phase, on the device all the three leds
will blink simultaneously, and the outgoing calls are forbidden: the user will hear in the phone a
single continuous tone for few seconds.
The same situation could be present also far from State boundaries but using a SIM card of Virtual
GSM Operator: in this case the tariff remain the same.
To enable the device for outgoing calls in these situations it is necessary insert a code using the
phone keypad (set DTMF selection) connected to the TEL1 or TEL2 ports.
