5. SIM CARD ACQUISITION
and INSTALL

1)Obtain your personal SIM card from the mobile
telephone company of your choice.
You will receive a telephone number and a PIN code
with your SIM card.

2)Cancel the SIM card's PIN code.

( No PIN code when use the SIM card )

The procedures to cancel the PIN code,
please use your own mobile to proceed as
the instruction manual.

Note :
To cancel the PIN code is the necessary
procedures, otherwise your GSM system will
be not working properly.

3)To guarantee flawless operation of your GSM
Control System, ensure that adequate signal
strength is permanently to and from your
mobile telephone network. Check this with
your mobile before installation.

4)Open the SIM card cover by loosing the " Screws for
the SIM card cover " ( 4-22, Fig. 3 ). Install the SIM
card properly into the " SIM card holder " ( 4-23, Fig. 3 ).
