Installation

For a correct installation, turn the device OFF and read the following instructions.

3) To cancel a wrong PIN code, hang up before sending the “#” (hash) button.
4) If the PIN code is correct you will hear the configuration tone (continuous tone, repeated twice).
5) Hook on the phone and wait for detection of the NETWORK network.
6) If the PIN code is wrong you will hear the ‘wrong configuration’ tone (single long tone).

ATTENTION: PIN and PUK codes are present on PIN-PUK card provided by NETWORK Operator when
you buy the SIM card.
Please note that, as on a cell phone, you have 3 tries to enter the right PIN code. After 3 wrong PIN codes, you must insert the PUK code and a new PIN code.
If you insert a wrong PUK code 10 times, the SIM card will be blocked.

The PIN code is automatically stored into Amigo GSM 2G/4G and it will be used when necessary. If the SIM card is removed or stolen then you must newly insert the PIN code manually.
To delete the PIN code from device memory, enter #*99# code using the phone keypad connected to TEL1 or TEL2 connector.

Check the good level of Network signal and if necessary try to improve it by placing the antenna in a different position.

Insert the PUK code

The request for PUK code is signalled with a different special tone with respect to the PIN tone request (double beep repeated with no pause).
Insert the PUK code using the phone keypad connected to the TEL1 or TEL2 port:

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

3) To cancel a wrong PUK code, hang up before sending the first “#” (hash).
4) If the PUK code is correct you will hear the configuration tone (continuous tone repeated twice).
5) Hook on the phone and wait for detection of the Mobile network.
6) If the PUK code is wrong you will hear the ‘wrong configuration’ tone (single long tone).

Roaming calls

By factory configuration the Amigo GSM 2G/4G detects automatically the Network operator. If the device is installed close to national borders, it could detect the foreign Network operator, and the billing could be higher during the voice calls.
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 national borders by using a Virtual Network Operator SIM card:
in this case the billing remains the same.
To enable the device for outgoing calls in these situations it is necessary to insert a code using the phone keypad
connected to the TEL1 or TEL2 ports.

Code: ##1111#1#1# – to confirm the automatic mode of Network detection, so, in this case, the roaming mode.
(Use this code with Virtual Network Operator SIM card whenthe device is installed close to the national borders and the manual selection of the Network operator fails.)

Code: ##1111#1#2#operator code# – to select the manual mode of Network detection, to a specific Network operator.
(Use this code in installations close to national borders, to manually select a specific Network operator)

In this last case the operator code is made of 5 digits, which is the operator code number worldwide assigned to each operator: for example in Italy:

Amigo GSM 2G/4G can also accept codes different from Italian ones.

If the device can detect the specific manually selected Mobile operator, the device will work in correct mode.
If the device cannot detect the specific Network operator, Amigo GSM 2G/4G will switch backto automatic mode and the roaming condition will be repeated.

If, after inserting previous code, the Amigo GSM 2G/4G works in roaming mode, the Status led is OFF.

The configuration will be automatically saved so after a device ON/OFF it is not necessary to repeat the above sequences.
The two codes above described could be accepted anytime.
To restore the factory configuration, it is enough dial the following DTMF code: #*99#

Redirection of calls

It is possible to configure the Gateway to detect up to 3 phone numbers dialed from the emergency phone, and redirect them to other phone numbers.

In the next configuration examples , whenever the Gateway detects the phone number 0331702611, it will call the phone number 0331263733.

Setup via DTMF with local phone
If the configuration is correct you will hear 2 long tones, if wrong only 1 long tone.

Setup via SMS
